Our photogrammetry software uses the logged GNSS data to geolocate each image, and then merges the images to create the DSM and a set of georeferenced orthophotos. We use a powerful office-based computer to prepare DSMs, since laptops are not sufficiently powerful to process the vast amount of data created during a survey flight, making on-site processing impractical.
You will receive these outputs from the photogrammetry processing stage:
- A 3D digital surface model of the area, in the form of a georeferenced RGB point cloud in XYZ, LAS or LAZ formats
- Orthomosaic maps of the area in GeoTIFF and Google Earth KML formats
- A series of individually geotagged high-resolution photographs of the site
- A raster DSM, which can be automatically contoured (SHP, PDF or DXF formats)
- A 3D textured mesh file
- A radiometric reflectance map (GeoTIFF)
- A comprehensive accuracy report
We aim to send your completed DSM and other outputs to you on the next working day following the survey flight.
