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.

Take a look at some DSMs and orthomosaic maps on our Case Studies pages.
