Description

[Technical field]

[0001] The present invention relates to a survey support device, a survey support method, and a survey support program. [Background technology]

[0002] Generally, for example, at construction sites, surveying is carried out to determine the position of stakes at the construction site, confirm the centering position of foundation piles, trace the terrain, manage height, etc. For such surveying, a Global Navigation Satellite System (GNSS), which receives signals from satellites to determine position, such as the Global Positioning System (GPS), may be used.

[0003] When a survey using GNSS is carried out, an operator sets up a surveying instrument at a surveying point, which is configured by attaching a receiving device for receiving signals from satellites and a processing device to a pole. When the receiving device receives a signal from a satellite, the processing device calculates the position coordinates of the current position of the surveying instrument based on the received signal.

[0004] [Patent Document 1] JP 2005-43088 A [Patent Document 2] JP 2006-3104 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when a survey is carried out using the above-mentioned surveying instrument, there is a problem in that it is difficult to use the position coordinate data obtained by the survey in real time. That is, while the position coordinate data obtained by the survey is usually used and viewed at a work site or the like that is far from the surveying site, the position coordinate data calculated by the arithmetic processing device attached to the surveying instrument cannot be used until the surveying instrument is brought back to the work site or the like.

[0006] Furthermore, even if a communication terminal device is attached to the surveying instrument and position coordinate data can be transmitted using the communication terminal device, the position coordinate data cannot be used externally until the transmission operation is performed by an operator at the surveying site, and real-time performance cannot be guaranteed.

[0007] The present invention has been made in consideration of the above, and aims to provide a survey support device, a survey support method, and a survey support program that can utilize data obtained by surveying using GNSS in real time. [Means for solving the problem]

[0008] A surveying support device according to one embodiment of the present invention has an acquisition unit that acquires satellite data from a surveying instrument that receives satellite data from a satellite during positioning, a calculation unit that calculates position coordinates of the surveying instrument based on the satellite data acquired by the acquisition unit, a determination unit that determines a status during positioning by the surveying instrument, and a generation unit that generates display screen information that displays the position coordinates calculated by the calculation unit in a display mode corresponding to the status determined by the determination unit.

[0009] This device calculates the position coordinates of the surveying instrument, determines the status during positioning, and generates display screen information that displays the position coordinates in a display format according to the status, so that by displaying the display screen information on a terminal device, for example, it becomes possible to easily check the accuracy of the position coordinates in real time. In other words, data obtained by surveying using GNSS can be used in real time.

[0010] In a surveying support device according to one embodiment of the present invention, in the above configuration, the determination unit determines the accuracy of the position coordinates calculated by the calculation unit based on information relating to the positioning accuracy, and the generation unit generates display screen information in which a marker of a display mode corresponding to the accuracy of the position coordinates is superimposed on the center of a map image.

[0011] According to this device, a marker whose display mode corresponds to the accuracy of the position coordinates can be displayed in the center of the map image, thereby improving visibility when checking the accuracy of the position coordinates.

[0012] In one aspect of the surveying support device of the present invention, in the above configuration, the judgment unit judges the quality of the communication status between the surveying instrument and the device itself, and the generation unit generates display screen information that displays an indicator indicating the quality of the communication status.

[0013] According to this device, the accuracy of the position coordinates displayed on the display screen information can be determined based on the quality of the communication state between the surveying instrument and the survey support device.

[0014] A surveying support device according to one embodiment of the present invention, in the above configuration, further has a measurement processing unit that measures distance, area or volume related to position coordinates calculated by the calculation unit, and the generation unit generates display screen information that displays the measurement results by the measurement processing unit.

[0015] This device can calculate the distance, area or volume for multiple points indicated by the position coordinates of the surveying instrument, and can instantly use the measurement results.

[0016] A surveying support device according to one embodiment of the present invention, in the above configuration, further has a drawing processing unit that acquires a drawing specified by a user and assigns specified coordinates specified by the user to the acquired drawing, and the generation unit generates display screen information that superimposes and displays the drawing at a position corresponding to the specified coordinates on a map image.

[0017] According to this device, for example, drawings such as design drawings can be displayed in the correct position on a map, making it possible to improve the efficiency of work at a survey site.

[0018] A surveying support device according to one embodiment of the present invention, in the above configuration, further includes a receiving unit that receives a recording instruction to record the position coordinates calculated by the calculation unit, and a memory unit that stores the position coordinates calculated by the calculation unit when the recording instruction is received by the receiving unit.

[0019] According to this device, the position coordinates of the surveying instrument are recorded in real time according to an external instruction, and for example, measurement processing and drawing processing using the history of the position coordinates are possible immediately. In addition, the recording of the position coordinates of the surveying instrument can be instructed from an external terminal device, and for example, a user in a location other than the surveying site can use the terminal device to assist in the surveying work.

[0020] In one aspect of the surveying support device of the present invention, in the above-mentioned configuration, the receiving unit receives a recording instruction to record position coordinates for every set time or set distance, and the memory unit stores the position coordinates calculated by the calculation unit continuously for every set time or set distance.

[0021] According to this device, the position coordinates of the surveying instrument are automatically recorded at set times or distances, so that changes in the position of the surveying instrument over time can be recorded and utilized.

[0022] A surveying support method according to one embodiment of the present invention acquires satellite data from a surveying instrument that receives satellite data from a satellite during positioning, calculates position coordinates of the surveying instrument based on the acquired satellite data, determines a status during positioning by the surveying instrument, and generates display screen information that displays the calculated position coordinates in a display mode corresponding to the determined status.

[0023] According to this method, the position coordinates of the surveying instrument are calculated, the status during positioning is determined, and display screen information is generated that displays the position coordinates in a display mode according to the status, so that the accuracy of the position coordinates can be easily confirmed in real time by displaying the display screen information on, for example, a terminal device. In other words, data obtained by surveying using GNSS can be used in real time.

[0024] A surveying support program according to one embodiment of the present invention causes a computer to execute a process of acquiring satellite data from a surveying instrument that receives satellite data from a satellite during positioning, calculating position coordinates of the surveying instrument based on the acquired satellite data, determining a status during positioning by the surveying instrument, and generating display screen information that displays the calculated position coordinates in a display mode corresponding to the determined status.

[0025] This program calculates the position coordinates of the surveying instrument, determines the status during positioning, and generates display screen information that displays the position coordinates in a display format according to the status, so that by displaying the display screen information on a terminal device, for example, it becomes possible to easily check the accuracy of the position coordinates in real time. In other words, data obtained by surveying using GNSS can be used in real time. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The embodiment described below is merely an example, and should not be construed as being limited by this description.

[0029] Fig. 1 is a diagram showing the configuration of a survey support system according to an embodiment of the present invention. The survey support system shown in Fig. 1 is configured by connecting a survey instrument 10, a terminal device 100, and a server device 200 via a network.

[0030] The surveying instrument 10 is a device carried by an operator to a surveying site, and has a structure in which a receiver for receiving signals from satellites and a communication terminal for transmitting and receiving data are attached to a rod-shaped pole. When an operator sets up the surveying instrument 10 at a surveying point, the receiver receives signals from the satellites and performs positioning. Then, the communication terminal transmits the positioning data obtained by the positioning to the server device 200. This positioning data includes information used for positioning, such as the satellite orbit and time, and information on the accuracy of positioning, such as the strength of the received signal and the number of satellites from which signals were received.

[0031] The terminal device 100 is a personal computer, a smartphone, a tablet terminal, or the like that can be connected to a network, and may be carried by an operator to a surveying site together with the surveying instrument 10, or may be installed in a work site different from the surveying site. The terminal device 100 communicates with the server device 200 via a network. Specifically, the terminal device 100 transmits a recording instruction to the server device 200 to instruct the server device 200 to record the position coordinates of the surveying instrument 10, and receives display screen information from the server device 200 that displays various processing results using the surveying results.

[0032] The server device 200 is a surveying support device capable of communicating with the surveying instrument 10 and the terminal device 100, and calculates the position coordinates of the surveying instrument 10 based on data received from the surveying instrument 10. The server device 200 also records the calculated position coordinates of the surveying instrument 10 in accordance with a recording instruction received from the terminal device 100. Furthermore, the server device 200 executes various processes using the position coordinates of the surveying instrument 10, and generates display screen information that displays the process results. The configuration and operation of the server device 200 will be described in detail later.

[0033] 2 is a block diagram showing the configuration of the terminal device 100. The terminal device 100 shown in FIG.

[0034] The input unit 110 accepts a user's input, and transmits an instruction or request corresponding to the input from the wireless communication unit 120 to the server device 200. Specifically, the input unit 110 transmits to the server device 200 a recording instruction to instruct the server device 200 to record the position coordinates of the surveying instrument 10 calculated in the server device 200, and a processing request to request processing such as measurement using the position coordinates.

[0035] The user of the terminal device 100 may be a worker who carries the surveying instrument 10 to the surveying site, or may be another user at a work site different from the surveying site. In other words, a worker who operates the surveying instrument 10 at the surveying site may send a recording instruction from the terminal device 100, or another user at a work site may send a recording instruction from the terminal device 100.

[0036] The wireless communication unit 120 is an interface that performs wireless communication via, for example, a mobile communication line, and transmits and receives signals to and from the server device 200. Specifically, the wireless communication unit 120 transmits recording instructions and processing requests output from the input unit 110 to the server device 200, and receives display screen information indicating processing results and the like from the server device 200.

[0037] The display unit 130 displays the display screen information received by the wireless communication unit 120. Specifically, the display unit 130 displays a screen showing the current position of the surveying instrument 10 in real time, a screen showing the processing results of measurements using position coordinates, and the like.

[0038] 3 is a block diagram showing the configuration of the server device 200. The server device 200 shown in FIG.

[0039] The communication unit 210 is connected to a network, and transmits and receives signals between the surveying instrument 10 and the terminal device 100. Specifically, the communication unit 210 receives positioning data from the surveying instrument 10. In addition, the communication unit 210 receives recording instructions and processing requests from the terminal device 100, and transmits display screen information to the terminal device 100.

[0040] The positioning data acquisition unit 220 acquires positioning data received from the surveying instrument 10. That is, the positioning data acquisition unit 220 acquires positioning data that is constantly transmitted from the surveying instrument 10 and includes information used for positioning and information related to the accuracy of positioning.

[0041] The position coordinate calculation unit 230 calculates the position coordinates of the surveying instrument 10 based on the positioning data acquired by the positioning data acquisition unit 220. That is, the position coordinate calculation unit 230 calculates the position coordinates of the surveying instrument 10 from the raw data that the surveying instrument 10 receives from a satellite. At this time, if the surveying instrument 10 is performing RTK positioning in which correction data is received from a predetermined reference station, the position coordinate calculation unit 230 may use the correction data to more accurately calculate the position coordinates of the surveying instrument 10. When RTK positioning is performed, the position coordinate calculation unit 230 can calculate position coordinates that include an error of, for example, about several centimeters.

[0042] The position coordinate calculation unit 230 notifies the display information generation unit 250 of the calculated position coordinates. When a recording instruction from the terminal device 100 is received by the communication unit 210, the position coordinate calculation unit 230 stores in the storage unit 240 the positioning information in which the calculated position coordinates are associated with the positioning time and the like.

[0043] The storage unit 240 stores various information including the position coordinates of the surveying instrument 10. Specifically, the storage unit 240 stores positioning information 241 that associates the position coordinates of the surveying instrument 10 calculated by the position coordinate calculation unit 230, the identification information of the surveying instrument 10, and the positioning time. The storage unit 240 also stores in advance map information 242 that includes the surveying site where the surveying by the surveying instrument 10 is performed.

[0044] The display information generating unit 250 generates display screen information to be displayed on the terminal device 100. Specifically, the display information generating unit 250 includes a status processing unit 251, a measurement processing unit 252, a drawing processing unit 253, and a screen generating unit 254.

[0045] The status processing unit 251 acquires information on the accuracy of positioning from the positioning data received from the surveying instrument 10, and judges the status at the time of positioning. Then, the status processing unit 251 determines the display mode of the position coordinates calculated by the position coordinate calculation unit 230 according to the status at the time of positioning. Specifically, the status processing unit 251 judges the accuracy of the position coordinates calculated by the position coordinate calculation unit 230 based on the reception state of the signal from the satellite in the surveying instrument 10. Then, the status processing unit 251 determines the display mode of the displayed numerical value of the position coordinates and the color or shape of the marker of the surveying instrument 10 according to the accuracy of the position coordinates. Furthermore, the status processing unit 251 determines the display mode of an indicator indicating the quality of the communication state based on the communication state between the surveying instrument 10 and the server device 200. That is, the status processing unit 251 generates an indicator with a different display mode such as a color or shape according to the state of the communication line between the surveying instrument 10 and the server device 200.

[0046] When the status processor 251 reads out the positioning information 241 from the storage unit 240 in response to a processing request from the terminal device 100, the status processor 251 also determines the display mode of the position coordinates based on the accuracy of the stored position coordinates.

[0047] The measurement processing unit 252 executes a measurement process of distance, area or volume from the position coordinates calculated by the position coordinate calculation unit 230 or the position coordinates stored by the storage unit 240 in response to a processing request from the terminal device 100. Specifically, when the design coordinates specified by the user are acquired from the processing request, the measurement processing unit 252 calculates the distance between the position coordinates of the current position of the surveying instrument 10 and the design coordinates, and notifies the screen generation unit 254 of the calculation result. In addition, when the designation of multiple points by the user is acquired from the processing request, the measurement processing unit 252 calculates the distance between the designated points and the area or volume of a polygon or solid having the designated points as vertices, and notifies the screen generation unit 254 of the calculation result.

[0048] The drawing processing unit 253 sets coordinates on a drawing designated by a user in response to a processing request from the terminal device 100, and sets the display position of the drawing. Specifically, the drawing processing unit 253 acquires a drawing, such as a floor plan designated by a user, from the processing request, and further acquires designated coordinates designated for at least two points in the drawing. Then, the drawing processing unit 253 outputs the drawing to which the designated coordinates have been assigned to the screen generating unit 254.

[0049] In response to a processing request from the terminal device 100, the screen generating unit 254 acquires the map information 242 from the storage unit 240 and generates a screen showing the processing result by the status processing unit 251, the measurement processing unit 252, or the drawing processing unit 253. Specifically, the screen generating unit 254 superimposes a marker in a display mode reflecting the status at the time of positioning on the map information 242, and generates a current position screen showing the current position of the surveying instrument 10. The screen generating unit 254 also generates a result screen showing the calculation result of the distance, area, or volume together with the map information 242. Furthermore, the screen generating unit 254 superimposes a drawing to which a specified coordinate has been assigned on the map information 242, and generates a superimposed screen showing the drawing specified by the user superimposed at an appropriate position on the map. The screen generating unit 254 transmits the generated screen from the communication unit 210 to the terminal device 100 which is the source of the processing request.

[0050] Next, a survey support method using the server device 200 configured as above will be described with reference to a flow chart shown in FIG.

[0051] The surveying instrument 10 constantly transmits positioning data from the surveying site to the server device 200. The positioning data is received by the communication unit 210 of the server device 200 and acquired by the positioning data acquisition unit 220 (step S101). Then, based on the positioning data from the surveying instrument 10, the position coordinates of the current position of the surveying instrument 10 are calculated by the position coordinate calculation unit 230 (step S102). Thereafter, the calculation of the position coordinates of the current position of the surveying instrument 10 continues while the positioning data from the surveying instrument 10 is being received.

[0052] On the other hand, when a connection request is received from the terminal device 100 via the network, the server device 200 executes a predetermined authentication process to authenticate the connection by the terminal device 100 (step S103). After that, the server device 200 becomes able to communicate information related to the surveying instrument 10 with the terminal device 100.

[0053] When the position coordinates of the current position of the surveying instrument 10 are calculated by the position coordinate calculation unit 230, the status processing unit 251 acquires information about the accuracy of the positioning and determines the status at the time of positioning (step S104). That is, the accuracy of the calculated position coordinates is determined from the strength of the received signal from the satellite at the time of positioning and the number of satellites from which the signal was received. Then, the status processing unit 251 determines the display mode of the position coordinates according to the accuracy. That is, the display mode of the numerical value of the position coordinates and the color or shape of the marker of the surveying instrument 10, etc., is determined to correspond to the status at the time of positioning. Furthermore, the status processing unit 251 determines the display mode of an indicator showing whether the communication state is good or bad based on the communication state between the surveying instrument 10 and the server device 200.

[0054] The display mode of the determined position coordinates is notified to the screen generation unit 254, and the screen generation unit 254 generates a current position screen showing the current position of the surveying instrument 10 (step S105). That is, a current position screen is generated in which the numerical values ​​of the position coordinates of the current position are displayed in a display mode reflecting the status at the time of positioning, and a marker in a display mode reflecting the status at the time of positioning is displayed in the center of the map image. The current position screen also includes an indicator showing the quality of the communication state between the surveying instrument 10 and the server device 200. The generated current position screen is transmitted from the communication unit 210 to the terminal device 100, and is displayed by the display unit 130 of the terminal device 100.

[0055] Fig. 5 is a diagram showing an example of a current position screen displayed on the terminal device 100. As shown in Fig. 5, a map image 301 is displayed on the current position screen, and a marker 311 indicating the current position of the surveying instrument 10 is superimposed on the center of the map image 301. The display mode of the marker 311, such as the color or shape, corresponds to the status at the time of positioning.

[0056] The current position screen also displays an indicator 312 that indicates whether the communication state between the surveying instrument 10 and the server device 200 is good or bad. The current position screen also displays position coordinates 313 of the current position of the surveying instrument 10, which correspond to the marker 311. The position coordinates 313 include position coordinates based on latitude, longitude, and altitude directly obtained from the positioning data, position coordinates in a plane rectangular coordinate system having a specified origin, and position coordinates in a local coordinate system having an origin set by the user.

[0057] In this way, the current position of the surveying instrument 10 is displayed in a manner that corresponds to the status at the time of positioning, so that the accuracy of the position coordinates can be easily confirmed in real time. Then, based on the confirmed accuracy, it can be determined whether or not to record the position coordinates of the current position of the surveying instrument 10.

[0058] The current position screen displays record instruction buttons 314, 315 for recording position coordinates 313 of the current position of the surveying instrument 10. The record instruction button 314 is a button for issuing an instruction to record the position coordinates 313 of the current position of the surveying instrument 10, and the record instruction button 315 is a button for issuing an instruction to continuously record the position coordinates 313 of the surveying instrument 10 at set time intervals or set distance intervals, respectively. By pressing the record instruction buttons 314, 315, the user of the terminal device 100 can transmit an instruction to record the position coordinates of the surveying instrument 10 to the server device 200.

[0059] After the current position screen is transmitted to the terminal device 100, the server device 200 waits for a recording instruction from the terminal device 100 (step S106). Then, when the user of the terminal device 100 viewing the current position screen presses the recording instruction button 314 or the recording instruction button 315, the recording instruction is received by the server device 200 (step S106 Yes). Upon receiving the recording instruction, the positioning information 241 including the position coordinates calculated by the position coordinate calculation unit 230 is stored in the storage unit 240 (step S107). If the recording instruction is not received (step S106 No), the currently calculated position coordinates are not recorded, and the acquisition of positioning data from the surveying instrument 10 and the calculation of position coordinates are continued.

[0060] In this way, the server device 200 calculates the position coordinates of the surveying instrument 10 from the positioning data constantly transmitted from the surveying instrument 10 to the server device 200, and records the position coordinates of the surveying instrument 10 in response to a recording instruction from the terminal device 100. Therefore, the position coordinates of the surveying instrument 10 are recorded in real time in the server device 200, and, for example, measurement processing and drawing processing using the history of the position coordinates become possible immediately. Also, the terminal device 100 can instruct the recording of the position coordinates of the surveying instrument 10, and, for example, a user in a location different from the surveying site can use the terminal device 100 to assist in surveying work.

[0061] Next, a specific method of using the position coordinates calculated and recorded as described above will be described. Fig. 6 is a flow diagram showing an example of a measurement process. The measurement process shown in Fig. 6 is mainly executed by the measurement processing unit 252 of the server device 200.

[0062] When a user of the terminal device 100 inputs predetermined design coordinates to the input unit 110, a processing request including the design coordinates is transmitted from the wireless communication unit 120 to the server device 200. This processing request is received by the communication unit 210 of the server device 200, and the design coordinates are acquired by the measurement processing unit 252 (step S201).

[0063] Then, the measurement processing unit 252 acquires the position coordinates of the current position of the surveying instrument 10 from the position coordinate calculation unit 230, and calculates the distance between the position coordinates of the current position of the surveying instrument 10 and the design coordinates (step S202). The calculated distance is notified from the measurement processing unit 252 to the screen generation unit 254, and the screen generation unit 254 generates a confirmation screen for confirming the distance from the current position of the surveying instrument 10 to the design coordinates (step S203). The generated confirmation screen is transmitted from the communication unit 210 to the terminal device 100, and is displayed by the display unit 130 of the terminal device 100.

[0064] Fig. 7 is a diagram showing an example of a confirmation screen displayed on the terminal device 100. As shown in Fig. 7, the confirmation screen displays a map image 301, and a marker 311 indicating the current position of the survey instrument 10 is superimposed on the map image 301. The display mode of the marker 311, such as the color or shape, corresponds to the status at the time of positioning. Furthermore, a marker 321 corresponding to the design coordinates is superimposed on the map image 301, and the distance between the current position of the survey instrument 10 and the design coordinates is displayed. Also, an indicator 312, position coordinates 313, and a record instruction button 314 are displayed on the confirmation screen, similar to the current position screen described above.

[0065] In this way, the distance between the current position of the surveying instrument 10 and the design coordinates is displayed in real time, so that an operator carrying the surveying instrument 10 can easily reach the design coordinates by visually checking the confirmation screen at the surveying site.

[0066] 8 is a flow diagram showing another example of the measurement process. The measurement process shown in FIG.

[0067] When the user of the terminal device 100 requests the area of ​​a polygon having a vertex that is a selected point, a processing request for calculating the area is transmitted from the wireless communication unit 120 to the server device 200. This processing request is received by the communication unit 210 of the server device 200 and acquired by the measurement processing unit 252.

[0068] Then, the measurement processing unit 252 acquires position coordinates of a plurality of selection points selected by the user (step S301). Specifically, the position coordinates recorded by the user pressing the record instruction button or the position coordinates selected by the user from the positioning information 241 in the storage unit 240 are acquired as the position coordinates of the selection points. When the position coordinates of the plurality of selection points are acquired, the area of ​​a polygon having these selection points as vertices is calculated (step S302). The calculated area is notified from the measurement processing unit 252 to the screen generation unit 254, and the screen generation unit 254 generates a result screen showing the calculation result of the area (step S303). The generated result screen is transmitted from the communication unit 210 to the terminal device 100 and displayed by the display unit 130 of the terminal device 100.

[0069] Fig. 9 is a diagram showing an example of a result screen displayed on the terminal device 100. As shown in Fig. 9, the result screen displays a map image 301, a marker 311, an indicator 312, and a record instruction button 314, similar to the current position screen described above. The result screen also displays a calculation button 331 for requesting the next measurement process, and an area calculation result 332. The calculation result 332 may include the area calculation result of the current measurement process, as well as the area calculation results of the previous measurement processes together with the calculation date and time.

[0070] 9, a marker 311 indicating the current position of the surveying instrument 10 is displayed on the map image 301 of the result screen, but markers indicating the positions of the vertices of a polygon for which the area is to be calculated may be displayed on the map image 301. Also, while the measurement process for calculating the area of ​​a polygon having multiple selected points as vertices has been described here, it is also possible to realize a measurement process for calculating the distance between multiple selected points and a measurement process for calculating the volume of a solid having multiple selected points as vertices.

[0071] In this way, the distance, area or volume for a plurality of selected points is displayed, so that the position coordinates of the surveying instrument 10 can be recorded as the selected points, and the measurement processing results such as distance, area or volume can be used immediately.

[0072] 10 is a flow diagram showing an example of the drawing processing. The drawing processing shown in FIG.

[0073] When a user of the terminal device 100 requests that a desired drawing be placed on a map, a processing request including data of the desired drawing and requesting the placement of the drawing is transmitted from the wireless communication unit 120 to the server device 200. This processing request is received by the communication unit 210 of the server device 200, and the drawing data is acquired by the drawing processing unit 253 (step S401).

[0074] Then, the drawing processing unit 253 accepts the user's designation of position coordinates for at least two points on the drawing. That is, for example, a screen that displays the drawing and prompts the user to input points on the drawing and the position coordinates of these points is displayed on the display unit 130 of the terminal device 100. When the user designates position coordinates for at least two points on the drawing, information on the designated position coordinates is transmitted from the terminal device 100 to the server device 200, and the designated coordinates are acquired by the drawing processing unit 253 (step S402).

[0075] Then, the drawing processing unit 253 assigns the designated coordinates to the drawing, and the drawing having the position information is output to the screen generating unit 254. In the screen generating unit 254, the map information 242 is read from the storage unit 240, and the drawing to which the designated coordinates have been assigned is superimposed on the map information 242 to generate a superimposed screen (step S403). That is, the screen generating unit 254 generates a superimposed screen in which the drawing is superimposed at a position on the map corresponding to the designated coordinates. The generated superimposed screen is transmitted from the communication unit 210 to the terminal device 100, and is displayed by the display unit 130 of the terminal device 100.

[0076] Fig. 11 is a diagram showing an example of a superimposed screen displayed on the terminal device 100. As shown in Fig. 11, the superimposed screen displays a map image 301, a marker 311, an indicator 312, position coordinates 313, and a record instruction button 314, similar to the current position screen described above. A drawing 341 designated by the user is displayed superimposed on the map image 301 on the superimposed screen. This drawing 341 is displayed at an appropriate position on the map according to the designated coordinates.

[0077] In this way, since the drawing is displayed at the appropriate position on the map, for example, design drawings can be displayed on the map to improve the efficiency of work at the survey site. Specifically, for example, a drawing showing the altitude limit by contour lines can be displayed at the appropriate position on the map of the construction site, and the height of construction equipment such as cranes installed at the construction site can be efficiently set.

[0078] As described above, according to this embodiment, the surveying instrument receiving the GNSS signal constantly transmits positioning data to the server device, and the server device calculates the position coordinates of the surveying instrument from the positioning data, determines the status during positioning, and causes the terminal device to display the position coordinates in a display mode according to the accuracy. Then, the server device records the position coordinates of the surveying instrument according to a recording instruction based on the accuracy of the position coordinates. Therefore, the position coordinates of the surveying instrument are recorded in the server device in real time, and measurement processing and drawing processing using the history of the position coordinates, for example, become possible immediately. In other words, data obtained by surveying using GNSS can be used in real time.

[0079] In the above embodiment, the communication terminal of the surveying instrument 10 and the terminal device 100 are provided separately, but it is also possible to integrate the communication terminal of the surveying instrument 10 and the terminal device 100. In this case, the integrated terminal device may be attached to the surveying instrument 10, or may be carried by an operator who carries the surveying instrument 10 to the surveying site.

[0080] The processing by the server device 200 described in the above embodiment can also be written as a computer-executable program. In this case, the program can be stored in a computer-readable and non-transitory recording medium and installed in the computer. Examples of such recording media include portable recording media such as CD-ROMs, DVD disks, and USB memories, and semiconductor memories such as flash memories. [Explanation of symbols]
