The Six Best Programs for Topography.
The best surveying software
Surveying is a discipline that involves describing and representing the shapes of the terrain in plan and relief. The use of digital tools has become essential in this branch of engineering.
Surveying software allows for the creation of surveys, plans, digital models, topographic maps, etc.
Presentation of different types of surveying software
-
Computer-aided design (CAD) software
CAD software is used to create plans and synthesis drawings. It allows for the editing of precise and professional plans in a short amount of time.
-
3D modeling software
3D modeling software allows for the creation of very precise digital models of terrain, structures, and buildings. These models can be created using survey data collected on the field or from point clouds obtained through photogrammetry.
-
Satellite image processing software
Satellite image processing software can obtain information about the terrain such as relief, vegetation, and snow cover. They are particularly useful for geomorphology and ecology studies.
-
Topographic data processing software
Topographic data processing software can transform raw data into useful geographical information. They are useful for creating plans, maps, digital terrain models, etc.
