Resulting from flights at low altitudes coupled with High Definition (HD) photographic sensors, the images have very fine resolutions with pixels varying from 2 to 10 centimeters. Our aerial shots are then:
- Post processed
- Georeferenced (UTM, Lambert 93, CC...)
These data are then delivered to you in a georeferenced digital format compatible for integration into your Geographic Information System (GIS / WebGIS).
Digital Surface Model (DSM)
A Digital Surface Model (DSM) or elevation model (DEM) is a 3D representation of the subsoil (i.e. of all objects on the surface of the earth), from vegetation to bridges, including homes.
A high recovery rate of aerial photographs allows - by photogrametric processing - to produce this type of deliverable
The altimetric details of the MNS / MNE produced are between 1 and 5 cm in elevation.
- Digital Surface Model
- Contour lines
- Shading to detect micro-reliefs
The photogrametry process allows 3D modeling, textured and georeferenced.
Areas of use
- Structural monitoring
- Coastal erosion
