Surveying and mapping

Aerial topography is based on the acquisition of georeferenced aerial images using our professional drones in order to perform surveys and mapping. Drones significantly reduce the time spent collecting field data. You can also reach places where sending people could be dangerous. This is particularly useful in most construction, surveys and topography projects.

High-precision aerial topography

Our main concern using this technique is the precision. In order to guarantee a centimeter resolution, geo-referenced images are taken with high-quality sensors can be coupled with high-tech GPS. The precision is always doubled-checked post-treatment into our software. We are aware that a high degree of precision is critical for most of aerial photography applications.

Georeferenced 3D models

A high-end photogrammetry software is used to convert images from drones into 3D models. We transfer our skills and expertise in subsurface 3D geomodeling to surface 3D modeling. Models are then converted into high resolution orthomosaic models and exported as maps and other formats (see below). With a georeferenced 3D model, your projects already get a valuable added-value.

Exploitable data

Being a very important step, georeferenced orthomosaic models are exported in a wide range of formats. We can also adapt to our clients requirements. The files are compatible with more common software in the market as AUTODESK or ArcGIS: obj/.ply, GeoTIFF, .dem, .kml, .xyz files, contour lines, etc.
