Problems solved by technology

However, in the pre-project surveying and mapping in areas where basic data are lacking, how to obtain control point results that meet the requirements of the pre-project surveying and mapping is a major technical problem that plagues electric power surveying and mapping personnel.
When conducting electrical engineering surveys in mountainous or remote areas, the control points are relatively rare or even have no measurement control point results. Even if there are control points, long-distance joint measurement is required, which is time-consuming and laborious
At the same time, even if there are control point results in some areas, since the coordinates of the survey control points are secret-related results, they need to be approved by the surveying and mapping administrative department.

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0020] see figure 1 , the method for obtaining results of measurement control points in areas where basic data is lacking in the present invention comprises the following steps:

[0021] Step 1. Select the pile position of the measurement control point in the surveying and mapping area, bury the control point mark, use GPS equipment to measure satellite data in static mode, and calculate the WGS84 coordinates of the control point according to the measurement data:

[0022] Embedding control point signs in the surveying and mapping area is the basis for obtaining control point results. After the GPS device measures the satellite data of the control point in a static mode, use the GPS device software to convert the measurement data into a Rinex format file (the suff...

Abstract

The invention discloses an acquisition method for achievements at a survey control point in a region lacking in basic data. The method comprises the following steps: step 1, selecting the pile position of a survey control point in a surveying and mapping area, burying a control point sign, measuring satellite data according to a static mode by using GPS equipment and calculating WGS84 coordinates of the control point according to measurement data; step 2, acquiring and selecting a label point with both WGS84 coordinates and national coordinates in a surrounding conversion area of the surveying and mapping area as a superposition point; step 3, solving the conversion relation between the WGS84 coordinates and the national coordinates; and step 4, calculating the national coordinates of the control point according to the WGS84 coordinates of the control point and the conversion relation. The method provided by the invention has the characteristics of convenient and fast acquisition of achievements at the survey control point, high precision of the achievements and capacity of meeting surveying and mapping requirements of an engineering project in an early stage, and can be widely applied to the field of surveying and mapping technology.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a method for acquiring results of survey control points in areas lacking basic data. Background technique [0002] At present, the surveying and mapping topographic maps of engineering projects need to use the coordinate results of national surveying and mapping control points. However, in the pre-project surveying and mapping in areas where basic data are lacking, how to obtain control point results that meet the requirements of the project’s preliminary surveying and mapping is a major technical problem that plagues electric power surveying and mapping personnel. When carrying out electrical engineering surveys in mountainous or remote areas, there are relatively few control points or even no measurement control point results. Even if there are control points, long-distance joint measurement is required, which is time-consuming and laborious. At the same time, ev...
