What are the steps of terrain data processing in digital surveying software?

What you may ask is what are the steps of terrain data processing in digital mapping software? The steps are as follows:

1. Make a detailed and clear work plan and determine the implementation plan after approval;

2. Collect and sort out the original and existing data of the survey area, and prepare the systematic topographic survey technical scheme according to the actual situation;

3, organize relevant professionals, in the formation of the project department at the same time, the establishment of technical portfolio quality supervision organization;

4. With the goal of comprehensive topographic survey, prepare various surveying and mapping instruments and tools in detail and draw survey marks;

5. When controlling the survey, in order to save the production cost, temporary ground signs are used as the map roots;

6. The collection of field data is very common in topographic map survey, and the information data includes the plane position and elevation data of topographic points and characteristic points;

7, unified computer office information data processing, drawing and data sorting need digital assistance;

8, the implementation of quality supervision and acceptance.
