Airborne topographic survey covering the full project area. The classified cloud lets us derive the terrain model, contours and cross sections without returning to the field for every new question. The survey is tied to on-site control points and checked against independent verification points.
What is included
- Site review and flight plan for relief and access
- Control and check points measured with GNSS
- LiDAR flight with GNSS/IMU trajectory (RTK / PPK)
- Flight-line adjustment and ground classification
- Quality control against the check points
Deliverables
- Classified point cloud (LAS / LAZ)
- Digital terrain model (DTM)
- Contours at agreed interval
- Cross sections
- Survey technical report
Applications
- Detailed design
- Pad and platform design
- Drainage studies
- Earthworks planning
What we need from you
- Area polygon (KML, KMZ, DWG or SHP)
- Project coordinate system and benchmark, if any
- Contour interval and working scale
- Site access and on-site contact
Formats LAS · LAZ · DWG · DXF · LandXML · GeoTIFF · PDF
Achievable accuracy depends on flight height, point density, ground control and vegetation cover. It is set in the proposal and reported with its residuals in the technical report.
