Description

[Technical field]

[0001] The present invention relates to a work management method, a work management system, and a work management program. [Background technology]

[0002] In recent years, there has been much research into using information on field operations to analyze agricultural management.

[0003] Patent Document 1 discloses a technique for receiving operation information from an implement used in work in a farm field, and estimating the type of work performed in the farm field based on the received operation information. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-087361 Summary of the Invention [Problem to be solved by the invention]

[0005] The work type estimated by the technology described in Patent Document 1 may differ from the work type of the work actually performed. For this reason, a user, such as a worker or a field owner, sets whether or not the estimated work type is the same as the work type of the work actually performed. Here, when work is being performed in many fields, the user may not be able to easily distinguish between fields where the work type has been confirmed and fields where it has not been confirmed.

[0006] In view of the above circumstances, one of the objectives of the present disclosure is to assist a user in identifying fields for which the user has confirmed the work type and fields for which the user has not confirmed the work type. Other objectives can be understood from the following description and the description of the embodiment. [Means for solving the problem]

[0007] The means for solving the problems will be described below using the numbers and symbols used in the description of the embodiment of the invention. These numbers and symbols are added in parentheses for reference purposes to show an example of the correspondence between the description of the claims and the description of the embodiment of the invention. Therefore, the description in parentheses should not be interpreted as limiting the scope of the claims.

[0008] To achieve the above object, a work management method according to one embodiment includes storing work data (300) representing a work performed in a first work area (400-1) and representing a confirmed work type and information associating the first work area (400-1), and an estimated work type that is estimated as a work performed in a second work area (400-2) and is not confirmed, and information associating the second work area (400-2). The work management method also includes displaying an image that distinguishes between the first work area (400-1) corresponding to the confirmed work type and the second work area (400-2) corresponding to the not confirmed estimated work type on a map.

[0009] To achieve the above object, a work management system (1000) according to an embodiment includes a data storage unit (150) and a display unit (250). The data storage unit (150) stores work data (300) that represents work performed in a first work area (400-1) and represents a determined work type and information associating the first work area (400-1), and that represents an estimated work type that is estimated as work performed in a second work area (400-2) and is not determined, and information associating the second work area (400-2). The display unit (250) displays an image that distinguishes between the first work area (400-1) corresponding to the determined work type and the second work area (400-2) corresponding to the estimated work type that is not determined on a map.

[0010] To achieve the above object, a task management program (310) according to one embodiment causes a calculation device (120) to store task data (300) representing a task performed in a first task area (400-1) and indicating a determined task type and information associating the first task area (400-1), and an estimated task type that is estimated as a task performed in a second task area (400-2) and not determined, and information associating the second task area (400-2). The task management program (310) also causes the calculation device (120) to display an image that distinguishes between the first task area (400-1) corresponding to the determined task type and the second task area (400-2) corresponding to the not determined estimated task type on a map.

[0013] (Embodiment 1) A work management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Fig. 1, the work management system 1000 includes a work management device 100 and a terminal 200. The work management device 100 is communicatively connected to the terminal 200 and a work device 30 via a network 20, for example, the Internet.

[0014] The work management apparatus 100 acquires operation information from the work apparatus 30 and estimates information related to the work, such as the work area, work period, and work type, based on the acquired operation information. The work period indicates the period during which the work apparatus 30 performed work in the field, and for example, indicates the work from when the engine of the work apparatus 30 starts to when it stops. The work type indicates the type of work performed in the field, such as plowing, leveling, fertilizing, planting, etc. The work apparatus 30 includes, for example, a tractor that pulls a work machine that performs work. The work machine includes, for example, a plow or rotary that performs plowing, a harrow that performs leveling, a broadcaster that performs fertilization, a transplanter that performs planting, etc.

[0015] The terminal 200 acquires information about the work from the work management apparatus 100 and provides the acquired information about the work to a user, for example, a worker or a field owner. For example, the terminal 200 displays an image showing a plurality of work areas 400 on a map, as shown in FIG. 2. The terminal 200 displays a first work area 400-1 in which the user has confirmed the work type and a second work area 400-2 in which the user has not confirmed the work type in a distinguishable manner. For example, the color of the area representing the first work area 400-1 in which the work type has been confirmed is different from the color of the area representing the second work area 400-2 in which the work type has not been confirmed. This allows the user to easily grasp the second work area 400-2 in which the work type has not been confirmed and the proportion of the second work area 400-2.

[0016] Furthermore, as shown in FIG. 3, the terminal 200 displays, in a graph, a total quantity 510 representing the quantity of the work area 400 in which work has been performed for each work type. The quantity of the work area 400 may be displayed by distinguishing between an unconfirmed quantity 520 representing the quantity of the second work area 400-2 in which the work type has not been confirmed and a confirmed quantity 530 representing the quantity of the first work area 400-1 in which the work type has been confirmed. This allows the user to easily check the trend of the work types being performed in the multiple work areas 400. Furthermore, the user can easily check the proportion of the second work area 400-2 in which the work type has not been confirmed for each work type, and further check the trend of the estimated work type. The terminal 200 may display a list of the total quantity 510 representing the quantity of the work area 400 in which work has been performed for each work type.

[0017] Here, the operation information includes information that represents the operating state of the working implement 30 when work is being performed in the field, such as the speed, steering angle, engine RPM, ON / OFF status of various clutches, position information of the working implement 30 at each time, and work period. When the working implement 30 is a vehicle that tows a work machine, such as a tractor, the operation information may also include information such as the PTO (power take-off) RPM when transmitting power to the work machine, and the hitch height and lift arm angle that represent the attitude of the work machine.

[0018] The operation information also includes position information of the work device 30. The work device 30 includes a positioning device, for example a GNSS (Global Navigation Satellite System) receiver, and acquires position information indicating the position of the work device 30 at each time it moves.

[0019] (Work management system configuration) The configuration of a work management device 100 included in the work management system 1000 shown in FIG. 1 will be described. The work management device 100 includes an input / output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work management device 100 is, for example, a computer. Information for the calculation device 120 to execute processing is input to the input / output device 110. The input / output device 110 outputs a result of the calculation device 120 executing the processing. The input / output device 110 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel. The input / output device 110 may be omitted.

[0020] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 130 transfers operation information acquired from the maintenance device 30 to the arithmetic device 120. Also, the communication device 130 transfers a signal generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces, for example, a network interface card (NIC) and a universal serial bus (USB).

[0021] The storage device 140 stores various data for determining the work type representing the work performed in the work area 400, such as the work data 300, and the work management program 310. The storage device 140 is used as a non-transitory tangible storage medium for storing the work management program 310. The work management program 310 may be provided as a computer program product recorded on a computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

[0022] The work data 300 includes data related to work in a farm field, for example data calculated from operation information from the work device 30. For example, as shown in Fig. 4, the work data 300 stores work area information representing the work area 400 (for example, the position and shape of the work area 400), work area information representing the work area of ​​the work area 400, work period information representing the work period, work type, and registration status information representing the registration status of the work type. The work area information, work period information, work type, and registration status information are stored in association with each other.

[0023] The registration status indicates whether the work type has been confirmed or not. For example, in the work data 300 of FIG. 4, in the work area 400 of "area A", the registration status indicated as "confirmed" indicates that the work type has been confirmed as "plowing". In the work area 400 of "area C", the registration status indicated as "unconfirmed" indicates that the work type has not been confirmed as "plowing". Hereinafter, the confirmed work type may be referred to as the confirmed work type.

[0024] 1 executes the work management program 310 and is used for various data processing for determining the work type of the work performed in the work area 400. For example, the calculation device 120 includes a central processing unit (CPU) and the like.

[0025] The calculation device 120 reads and executes the task management program 310, thereby realizing a data storage unit 150, an estimation unit 160, a determination unit 170, a compilation unit 180, and an output unit 190, as shown in FIG. 5. The data storage unit 150 stores task data 300. The estimation unit 160 acquires operation information from the task device 30 and estimates an estimated task type. The determination unit 170 determines the task type based on the determination information indicating that the user has confirmed the task type. The compilation unit 180 compilations the quantity of the task area 400 in which the task has been performed for each task type. The output unit 190 outputs area display information indicating the task area 400 to the terminal 200.

[0026] Next, the configuration of the terminal 200 will be described. As shown in FIG. 1, the terminal 200 includes an input / output device 210, a calculation device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the calculation device 220 to execute processing is input to the input / output device 210. In addition, the input / output device 210 outputs the result of the calculation device 220 executing the processing. The input / output device 210 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

[0027] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 230 transfers information acquired from the work management device 100 to the calculation device 220. Also, the communication device 230 transfers a signal generated by the calculation device 220 to the work management device 100. The communication device 230 includes various interfaces, for example, a network interface card (NIC) and a universal serial bus (USB).

[0028] The storage device 240 stores various data, for example, a display program 320, for displaying the working area 400 where the working device 30 has performed the work. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 320. The display program 320 may be provided as a computer program product recorded in a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server. The display program 320 may be provided by being recorded in a storage medium 1.

[0029] The arithmetic device 220 reads and executes the display program 320, thereby working together with the input / output device 210 to realize the display unit 250 as shown in Fig. 5. The display unit 250 acquires area display information representing the work area 400 from the work management device 100, and displays the area display information representing the work area 400. The display unit 250 also transmits determination information to the work management device 100 for determining the work type of the work performed in the work area 400, in response to a user operation.

[0030] (Operation of the work management device) When the arithmetic device 120 of the work management apparatus 100 receives operation information from the work apparatus 30, it reads and executes the work management program 310. By executing the work management program 310, the arithmetic device 120 executes the process shown in Fig. 6, which is a work management method.

[0031] In step S110, the estimation unit 160 determines the working area 400 in which the working apparatus 30 performed the work and the working period based on the operation information acquired from the working apparatus 30. For example, the estimation unit 160 determines the working area 400 based on the position information of the working apparatus 30 included in the operation information. For example, the working area 400 is represented by any closed figure, such as a polygon or a rectangle, that includes the position represented in the acquired position information. For example, the working area 400 is represented by a figure that surrounds all of the acquired position information. The working area information representing the determined working area 400 is newly stored in the work data 300 shown in FIG. 4 by the estimation unit 160.

[0032] Furthermore, the estimation unit 160 determines the work period from the time when the work device 30 is started to the time when the work device 30 is stopped as the work period. The estimation unit 160 stores work period information indicating the determined work period in the work data 300 in association with the newly added work area information.

[0033] The estimation unit 160 also stores in the task data 300 the worker who performed the task in the working area 400. The estimation unit 160 has worker association data that associates the task device 30 with the worker, and determines the worker based on the task device 30 that transmitted the operation information.

[0034] In step S120 shown in FIG. 6, the estimation unit 160 estimates an estimated task type representing the task type of the task performed in the task area 400 based on the operation information. For example, the estimation unit 160 estimates the estimated task type using a trained model obtained by machine learning. In this case, the trained model is trained to estimate the estimated task type from the operation information. The estimation unit 160 may also estimate the estimated task type based on the model of the task device 30. In this case, the storage device 140 stores task correspondence data that associates the model of the task device 30 with the estimated task type. The estimation unit 160 estimates the estimated task type based on the task correspondence data. The estimated task type is stored in the task data 300 shown in FIG. 4 by the estimation unit 160 in association with task area information representing the task area 400. In addition, the estimation unit 160 sets the corresponding registration status of the task data 300 to "unconfirmed".

[0035] 6, the output unit 190 outputs area display information that associates the work area information stored in the work data 300 with registration status information to the terminal 200. For example, the output unit 190 outputs area display information that distinguishes between a first work area 400-1 whose registration status indicates "confirmed" and a second work area 400-2 whose registration status indicates "unconfirmed." The area display information includes previously stored work area information in addition to newly added work area information.

[0036] In step S140, the display unit 250 of the terminal 200 displays an image showing the work area 400 on a map as shown in Fig. 2 based on the area display information acquired from the work management apparatus 100, and accepts a work type confirmation operation by the user. For example, the display unit 250 displays an image showing a first work area 400-1 in which the work type has been confirmed and a second work area 400-2 in which the work type has not been confirmed in a distinguishable manner. The user can easily understand the second work area 400-2 in which the work type has not been confirmed.

[0037] When a confirmation operation is input to the input / output device 210, the display unit 250 transmits confirmation information indicating the correct work type to the work management device 100. When the confirmation information is transmitted, the process proceeds to step S150 shown in FIG. 6. For example, the user selects the second work area 400-2, whose work type has not been confirmed, on the input / output device 210 of the terminal 200. When the second work area 400-2 is selected, the display unit 250 displays work information 410 indicating the estimated work type of the second work area 400-2 in association with the selected second work area 400-2, as shown in FIG. 2. The user checks the displayed estimated work type. When the displayed estimated work type is the same as the work type of the work performed in the corresponding second work area 400-2, the user inputs a confirmation operation to confirm the work type, for example, an operation to select the confirmation button 411, to the input / output device 210. When the estimated work type differs from the work type of the work performed in the corresponding second work area 400-2, the user inputs a change operation to the input / output device 210 to change the work type, for example, an operation to select the change button 412. After performing the change operation, the user inputs the correct work type to the input / output device 210. Based on the confirmation operation or change operation, the display unit 250 outputs confirmation information indicating the correct work type to the work management device 100. When the confirmation operation is input to the input / output device 210, the confirmation information indicates that the estimated work type of the selected second work area 400-2 is correct. When the change operation is input to the input / output device 210, the confirmation information indicates the correct work type of the selected second work area 400-2.

[0038] 6, the display unit 250 also accepts a statistics display operation for displaying statistical information indicating the quantity of work areas 400 for each work type. When a statistics display operation is input without a confirmation operation being input, the display unit 250 transmits request information requesting the statistical information to the work management apparatus 100. When the request information is transmitted, the process proceeds to step S160.

[0039] In step S150, the determination unit 170 of the work management apparatus 100 determines the work type of the second work area 400-2 based on the determination information representing the correct work type. Specifically, the determination unit 170 acquires the second work area 400-2 represented in the determination information and the correct work type. The determination unit 170 sets the correct work type in the second work area 400-2 represented in the determination information in the work data 300 shown in FIG. 4, and changes the registration status to "confirmed". For example, when a confirmation operation, for example an operation to select the confirmation button 411, is input, the determination unit 170 changes the corresponding registration status to "confirmed". When a change operation is input, the determination unit 170 changes the work type of the second work area 400-2 to the work type represented in the determination information, and changes the registration status to "confirmed".

[0040] In step S160 shown in Fig. 6, the counting unit 180 counts up the quantity of the work area 400 for each work type based on the work data 300 shown in Fig. 4. For example, first, the counting unit 180 extracts one or more work types stored in the work data 300. In the example shown in Fig. 4, the counting unit 180 extracts "plowing" and "weeding" as the work types stored in the work data 300.

[0041] Next, the counting unit 180 counts the quantity of work areas 400 that correspond to one or more extracted work types among the work areas 400 stored in the work data 300. In the example shown in Fig. 4, the counting unit 180 obtains "4" as the quantity of work areas 400 whose work type is "plowing". In addition, the counting unit 180 obtains "1" as the quantity of work areas 400 whose work type is "weeding".

[0042] Furthermore, the counting unit 180 counts, for each work type, the quantity of the first work area 400-1 corresponding to the confirmed work type and the quantity of the second work area 400-2 corresponding to the unconfirmed work type based on the work data 300. In the example shown in FIG. 4, the counting unit 180 obtains "2" as the quantity of the first work area 400-1 where the work type is "plowing" and the registration status is "confirmed". The counting unit 180 obtains "2" as the quantity of the second work area 400-2 where the work type is "plowing" and the registration status is "unconfirmed". The counting unit 180 obtains "1" as the quantity of the first work area 400-1 where the work type is "weeding" and the registration status is "confirmed". The counting unit 180 obtains "0" as the quantity of the second work area 400-2 where the work type is "weeding" and the registration status is "unconfirmed".

[0043] 6, the output section 190 outputs statistical information indicating the quantity of work areas 400 for each work type to the terminal 200. The statistical information may indicate the quantity of work areas 400 for each work type, distinguishing between the quantity of first work areas 400-1 corresponding to a confirmed work type whose work type has been confirmed and the quantity of second work areas 400-2 corresponding to an estimated work type whose work type has not been confirmed.

[0044] In step S180, the display unit 250 of the terminal 200 displays the statistical information acquired from the work management device 100 on the input / output device 210. As shown in FIG. 3, the display unit 250 displays a total quantity 510 indicating the quantity of the work area 400 in which work has been performed, an unconfirmed quantity 520 indicating the quantity of the second work area 400-2 in which the work type has not been confirmed, and a confirmed quantity 530 indicating the quantity of the first work area 400-1 in which the work type has been confirmed. As shown in FIG. 3, the display unit 250 may indicate the total quantity 510 using the unconfirmed quantity 520 and the confirmed quantity 530, and indicate the ratio of the unconfirmed quantity 520 to the total quantity 510. The display unit 250 may also display the ratio of the unconfirmed quantity 520 to the total quantity 510 as a numerical value. By checking the image displayed on the input / output device 210, the user can grasp the ratio of the work area 400 in which the work type is unconfirmed for each work type.

[0045] In this way, the work management system 1000 assists the user in checking the work type.

[0046] (Modification) The configuration described in the embodiment is an example, and the configuration can be changed as long as the function is not impaired. For example, when the display unit 250 of the terminal 200 displays the quantity of the work area 400 for each work type shown in Fig. 3, the display unit 250 may display the quantity of the first work area 400-1 for which the work type has been determined and the quantity of the second work area 400-2 for which the work type has not been determined without distinguishing between them.

[0047] The display unit 250 may display the area of ​​the work area 400 instead of the quantity of the work area 400 in the graph shown in Fig. 3. In this case, in step S160 shown in Fig. 6, the aggregation unit 180 of the work management apparatus 100 aggregates the areas of the work areas 400 for each work type based on the work data 300 shown in Fig. 4 to calculate a total area. In addition, the aggregation unit 180 aggregates the area of ​​the first work area 400-1 corresponding to the confirmed work type and the area of ​​the second work area 400-2 corresponding to the unconfirmed work type for each work type to calculate the total area of ​​the first work area 400-1 and the total area of ​​the second work area 400-2. In step S170, the output unit 190 outputs statistical information indicating the area of ​​the work area 400 for each work type to the terminal 200. The statistical information may represent the area of ​​the work area 400 by distinguishing, for each work type, the area of ​​the first work area 400-1 corresponding to a confirmed work type whose work type has been confirmed, from the area of ​​the second work area 400-2 corresponding to an estimated work type whose work type has not been confirmed. In step S180, the display unit 250 of the terminal 200 displays the statistical information on the input / output device 210.

[0048] Furthermore, as shown in FIG. 7, the display unit 250 may display the quantity of the work area 400 for each work type, distinguishing between the workers who performed the work in the work area 400. In the example shown in FIG. 7, the first worker-specific graph 600-1 represents the quantity of the work area 400 in which the worker a performed the work, for each work type. The second worker-specific graph 600-2 represents the quantity of the work area 400 in which the worker b performed the work, for each work type. The worker-specific graph 600 may distinguish between an unconfirmed quantity 620 representing the quantity of the second work area 400-2 in which the work type has not been confirmed, and a confirmed quantity 630 representing the quantity of the first work area 400-1 in which the work type has been confirmed. The display unit 250 may display the total quantity 610 using the unconfirmed quantity 620 and the confirmed quantity 630, and display the ratio of the unconfirmed quantity 620 to the total quantity 610. This allows the user to confirm the work type of the work performed in the work area 400 for each worker. In addition, the user can easily compare the confirmation rate of the worker who is checking the work type with the confirmation rates of other workers. For example, the user can notify a worker whose confirmation rate is lower than the confirmation rates of other workers to check the work type. In this case, the counting unit 180 of the work management device 100 distinguishes between workers, counts the quantity of the work area 400 for each work type, and outputs statistical information indicating the counted quantity to the terminal 200.

[0049] The display unit 250 may distinguish between work area groups into which a plurality of work areas 400 are classified, instead of the workers, and display the quantity of work areas 400 for each work type. Here, a work area group includes a plurality of work areas 400 classified based on the similarity between two work areas 400. The similarity represents whether the work performed in two work areas 400 where work of the same work type is performed is similar.

[0050] For example, the counting unit 180 of the task management apparatus 100 calculates the similarity between two task areas 400 based on the task data 300 shown in FIG. 4. For example, the similarity is calculated using the distance between the two task areas 400 and the time difference between the times when tasks were performed in the two task areas 400. For example, the similarity may be calculated based on a two-dimensional distance in which the distance between the task areas 400 and the time difference are each set as one axis. Specifically, the counting unit 180 calculates the Euclidean distance, which is calculated as the square root of the value obtained by adding the square of the distance to the square of the time difference. The counting unit 180 calculates the similarity by calculating the reciprocal of the calculated Euclidean distance. Alternatively, any distance, for example, Manhattan distance, may be used instead of the Euclidean distance.

[0051] In this case, the counting unit 180 classifies the work areas 400 according to the similarity in step S160 shown in Fig. 6. For example, the work areas 400 are classified so that two work areas 400 whose similarity is smaller than a threshold value are included in the same work area group. The counting unit 180 distinguishes between work area groups and counts the quantity of work areas 400 for each work type. In step S170, the counting unit 180 outputs statistical information indicating the counted quantity to the terminal 200. The display unit 250 of the terminal 200 displays the quantity of work areas 400 for each work type based on the statistical information and distinguishes between workers.

[0052] The display unit 250 may also display the quantity of work areas 400 on which work was performed on a specific date. In this case, the counting unit 180 counts the quantity of work areas 400 on which work was performed on a specific date for each work type, and outputs statistical information indicating the counted quantities to the terminal 200.

[0053] The work area 400 shown in Fig. 2 may represent a farm field. In this case, the work area 400 of the work data 300 shown in Fig. 4 represents a farm field, and in step S110 shown in Fig. 6, the estimation unit 160 determines the farm field where the work has been performed from the position information of the work device 30. For example, the estimation unit 160 determines the farm field including the position where the work device 30 performed the work as the farm field where the work has been performed. The display unit 250 displays the quantity of the farm fields where the work has been performed.

[0054] A single field may include multiple work areas 400. For example, in step S160 shown in FIG. 6, the tallying unit 180 of the work management apparatus 100 determines that the work type of the corresponding field has been determined when the registration status of all of the work areas 400 included in the single field is "determined." The tallying unit 180 determines that the work type of the corresponding field has not been determined when the registration status of at least one of the work areas 400 included in the single field is "undetermined." For each work type, the tallying unit 180 tallies the quantity of the first work area 400-1 corresponding to the determined work type and the quantity of the second work area 400-2 corresponding to the undetermined work type.

[0055] 6, the estimation unit 160 may determine the work period by any method. For example, the estimation unit 160 may determine the work period based on the time when the work implement 30 enters the farm field and the time when the work implement 30 leaves the farm field.

[0056] In step S140 shown in Fig. 6, the display unit 250 of the terminal 200 may display the work area 400 in which work was performed during a predetermined period, for example, a period from the present time to one month ago. In this case, in step S130, the output unit 190 extracts the work area 400 in which work was performed during the predetermined period from the work data 300 shown in Fig. 4. Specifically, the output unit 190 extracts the work area 400 whose work period falls within the predetermined period. Area display information representing the extracted work area 400 is output to the terminal 200.

Furthermore, some of the functions described in the embodiment and modified examples may be omitted as long as the necessary functions can be realized. For example, some or all of the processing of the work management apparatus 100 may be executed by the terminal 200. Also, some or all of the processing of the terminal 200 may be executed by the work management apparatus 100.

[0058] Furthermore, the work management system 1000 may not include the terminal 200, and may display area display information and statistical information on an external terminal not included in the work management system 1000. Furthermore, the display unit 250 of the terminal 200 may acquire map information from an external server not included in the work management system 1000, and display the map information showing the area display information on a map.
