Problems solved by technology

[0003] The existing surveying and mapping method is to use the total station for on-site surveying and mapping, but when performing data processing, it is necessary to read the N, E, and Z data of the total station for displaying points. During the displaying process, since the image is a two-dimensional map, The image is often represented as a line, making the image extremely difficult to recognize

Embodiment 1

[0025] Embodiment one: a kind of elevation surveying and mapping method, comprises a. station station is set, coordinates of station station, basic data are input in the total station, finishes the setting of survey point; Input into the total station to complete the setting of the backsight point; c. collect data of different observation points and record the three coordinate values ​​of N, E, and Z; d. transmit the data in the memory of the total station to the computer through data communication to generate DAT format data file; e. exchange the positions of N and E, N and Z, and E and Z respectively to obtain three different sets of data; f. open the southern CASS 9.1 digital topographic cadastral mapping system to The numerical points of the three combinations are processed separately to obtain three spread point maps; e. Select the one of the three spread points that is most in line with the actual building as the point spread map.

Embodiment 2

[0026] Embodiment two: a kind of facade surveying and mapping method, and the difference of embodiment one is: measurement content mainly comprises building inflection point coordinates, building structure, number of floors etc.; Building indoor floor, outdoor ground elevation; Building height ( The vertical distance from the indoor floor to the shading point); the height of the building (indoor clear height plus the thickness of the floor slab); the position of windows and balconies on the sunny side of the building.

[0027] Before the measurement, it is necessary to make preparations. Before the inspection, it is necessary to prepare for the charging of the instrument, accessories, tools, drawings, materials, recording supplies, etc., so as to avoid insufficient preparation and affect the operation.

[0028] When setting up the station, input the height, temperature and pressure of the total station itself, prism constant and other values ​​into the total station, and the ce...

Abstract

The invention relates to the field of surveying and mapping, in particular to a facade surveying and mapping method. The facade surveying and mapping method aims at solving the problems that an imageis a line after data is acquired by a total station, and is hardly recognized. According to the technical scheme, the facade surveying and mapping method includes the steps that a, a surveying stationis arranged; b, a backsight point is arranged; c, data of different observation points is acquired, and N, E and Z three-coordinate values are recorded; d, data in a memory of the total station is transmitted to a computer through data communication, and a data file in a digital mapping software format is generated; e, the positions of N and E, the positions of N and Z and the positions of E andZ are interchanged, and three different groups of data are obtained; f, mapping software is started, value points of the three groups of combinations are processed respectively, and three plot maps are obtained; e, the plot map, not a single line, in the three plot maps is selected as the final plot map. The N, E and Z three-coordinate positions are interchanged, and the problem that the image isformed into one line is avoided.

Description

technical field [0001] The invention relates to the field of surveying and mapping, more specifically, it relates to a method for facade surveying and mapping. Background technique [0002] Surveying and mapping is based on computer technology, photoelectric technology, network communication technology, space science, and information science, with the global positioning system (GPS), remote sensing (RS), and geographic information system (GIS) as the technical core. Points and boundaries obtain graphics and position information reflecting the current status of the ground through measurement means, which are used for planning, design and administrative management of engineering construction. [0003] The existing surveying and mapping method is to use the total station for on-site surveying and mapping, but when performing data processing, it is necessary to read the N, E, and Z data of the total station for displaying points. During the displaying process, since the image is...
