Real-time kinematic GPS (RTK-GRS) and total station integrated topographic surveying method and system with encoded data

Abstract

The invention relates to a real-time kinematic GPS (RTK-GRS) and total station integrated topographic surveying method and system with encoded data. When the data is surveyed outside, data collected by the RTK-GRS and the total station is respectively encoded according to a preset RTK-GRS coding standard and a preset total station coding standard. The function of two devices with high working efficiency is exerted without drawing a sketch map by handmade for saving the human resource. When the office work is processed, the surveying points of the landmarks can be automatically analyzed according to the same preset RTK-GPS coding standard and the same total station coding standard through the observation data with object codes collected outside, An automatic matching is conducted accordingto the landmark coding coupling standards of the preset total station, the RTK-GPS, a CASS for generating a CASS software interface file, and a topographic map can be automatically drawn by using a CASS software. The defects that a measuring point is searched by person and points are connected one by one by people can be avoided. The t real-time kinematic GPS (RTK-GRS) and total station integrated topographic surveying can be realized and the drafting efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of electric power engineering measurement, in particular to an integrated terrain measurement method and system with a coded RTK-GPS total station. Background technique [0002] At present, in domestic topographic map measurement technology, there are two common methods, one is to use total station topographic surveying and mapping topography and ground objects, and the other is RTK-GPS (Real-Time Kinematic GPS, dynamic real-time global positioning system) measurement method. [0003] The main method of the total station topographic survey is to collect all the detailed points and draw operations in the field, and the office personnel calculate the coordinates of all the survey points of the total station, and display all survey points on the map (usually, using AutoCAD as the platform) According to the field sketch, find the measuring points in the sketch in a large number of fragmentary points, and connec...

Problems solved by technology

Applying these two surveying and mapping methods, the field is responsible for collecting data and drawing sketches, and the interior is only responsible for processing the data. The operations of the interior and field are disconnected from each other. In addition, how to connect ground objects can only rely on the manual drawing of ground by field personnel. Therefore, when data processing is performed by the office personnel, it is necessary to manually search for all the measuring points of each feature in the field sketch against the hundreds of measuring points of the day, and then connect them point by point. line, the workload is huge and error-prone

[0005] On the other hand, CASS software (a digital topographic map measurement software, developed by Nanfang Digital Technology Co., Ltd.) is the most widely used software in the domestic topographic map surveying and mapping field. Most units use this software to survey and map topographic maps. However, This topographic map software is only an office data processing and mapping software. When processing topographic map data, you can only simply use CASS software to draw the measuring points on the map, and then manually connect the measuring points, which is very inefficient.
