Generation of orthophotos and DSM for environmental projects

Orthophotos and Digital Surface Models (DSM) gather basic spatial information for any environmental project: cartography, GIS, planning, boundary marking, landscaping, topography, etc.

The documents delivered to the client will be georeferenced to a coordinate system –geographic or projected-. On the day of the flight, coordinates of Ground Control Points -GCPs- will be registered with a GNSS receiver and post-treated back in the office. This process allows for submetric mapping and modelling.

In environmental studies taking aerial images of a forest will help assess the tree phytosanitary state -for instance, damage caused by leaf-feeding caterpillars or drought- or the measurement of tree height.

3D modelling for risks assessments

3D models are obtained from point clouds and they can be exported to software such as AutoCad Civil 3D, HEC-RAS, ArcGIS and QGIS. 3D Models allow to assess potential risks, such as flood events – the rise of the water level of a nearby river- or land sliding next to a road.

Aerial inventories in quarries and sawmills

Digital surface models may replace slower and more dangerous ground inventories in quarries or sawmills. Volumes of stone or timber  can be quickly and accurately calculated in a safer way.

Others: Environmental disasters, works progress, technical inspections

After an environmental disaster, such as forest fire or flooding, drones are the quickest and most efficient method to calculate the affected area and assess the losses. Thus, experts can save crucial amounts of time on writing their damage assessment reports.

Drones are the safest and quickest way to evaluate the progress of works at a site, to inspect wind turbines, dams, building facades, monuments, etc…
