Technical features of products:

Title 5000 2000 1000 500
Corresponds to the scale 1:5000 1:2000 1:1000 1:500
Spatial resolution of the orthophoto 30 sm 15 sm 7 sm 5 sm
Plane accuracy of an orthophoto is not worse than* 200 sm 80 sm 40 sm 20 sm
Height accuracy of DEM and 3D Model is not worse than** 66 sm 33 sm 16 sm 16 sm

* that means the average errors in the plane position of the reference and control points of the created orthophoto will not exceed these values, which corresponds to the regulatory documents.

** these values characterize the accuracy of the surface model, including continuous vegetation, grass, snow, etc.

Aerial surveys and desk works include:

  • obtaining permits for the aerial photography
  • aerial photography using Geoscan UAV
  • creation of orthophotos of the required scale
  • creation of DEMs

The execution of works is usually carried out from 1 to 4 weeks from the date of prepayment. The deadlines can be extended due to significant workloads.
