When is it needed
- Large sites, subdivisions, industrial sites.
- Road or network corridors.
- Vegetated areas (LiDAR).
Our work
- Flight plan. Height, overlaps and authorisations required for the area.
- Ground control points. Measured by GNSS, tied to the Lambert Morocco (Merchich datum) grid and to the NGM (Morocco's national levelling datum).
- Processing. Dense cloud, DTM (digital terrain model), contour lines.
- Check. On independent points, accuracy report.
Examples of assignments
- DTM of a project site
- Road corridor
- LiDAR survey under vegetation cover
What you receive
- DTM and contour lines
- Point cloud
- Check report
Reference framework
- Decision No. 68/98/ONIGT/CN (tolerances) of the ONIGT (National Order of Surveying Engineers)

Frequently asked questions
Does the drone replace a ground survey?
Not under trees, nor for property boundaries: ground measurements remain necessary.
