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