Topographic Survey

Method

Using our DJI matrice 350 drone equipped with L2 LiDAR sensor technology, we perform high-resolution topographic surveys with up to five returns per laser pulse, allowing us to extract a precise point cloud accurately differentiating between vegetation, water bodies, and ground surfaces. This multi-return capability enables precise mapping of dense forest canopies, rugged natural landscapes, and built environments, even in areas with complex terrain or heavy foliage. By combining aerial photogrammetry and LiDAR scanning, we generate detailed and colored digital elevation models (DEMs) and terrain analyses with sub-centimeter accuracy.

Deliverables - compatible with GIS and CAD software

1. High-Resolution Topographic Maps

Whether for site grading, hydrology analysis, forestry management, or infrastructure planning, our drone-based surveys offer an unparalleled level of precision and efficiency in topographic data collection

2. Georeferenced Orthophotos

We also provide comprehensive studies based on the data collected : contour maps, elevation heatmaps and hydrologic simulations.

3. 3D terrain models

3D terrain models capture detailed elevation and surface features, providing an accurate digital representation for topographic analysis, planning, and design.

4. LiDAR point clouds

Delivers dense, georeferenced spatial data, enabling precise terrain mapping, elevation modeling, and structural analysis for topographic surveys.
