Topographic survey – is a complex of activities performed for obtaining the information about the primary topographic plan and geodesic surveys.
Topography is one of the most requested forms of geodesic work. It’s necessary on every stage of building, urban planning, mining, land planning, infrastructure projecting, landscape projection, positioning of trees, their types and diameters, as well as discovering and correcting the borders of the land.
As a result of topographic work, client gets both, printed and electronic versions of the map.
A topographic survey, legitimate coordinate system, depicts in detail ground relief (landforms and terrain), drainage (lakes and rivers), forest cover, administrative areas, populated areas, transportation routes and facilities (including roads and railways), and other man-made features.
They have certain measures:
- 1:200, 1:100, 1:50 scale are used for landscape projection;
- 1:500 is used for buildings and constructions and happens to be the most popular forms used in everyday life;
- 1:1000 and 1:2000 scale topography is mostly used for small inhabited areas, contoured constructions , but in existing communications and constructive buildings the works needs to be done in measure 1:500;
- 1:5000 and 1:10000 scale are generally used for urban and regional planning. In these activities, the miscount shouldn’t be more than 15cm in inhibited areas, and 30 cm in non-inhibited.
See examples of topography below.
