А new technology of UAV-based thermal surveying by Geoscan

Previously, it was hardly possible to automatically align thermal images into a mosaic. Low contrast values of some frames caused the errors of automatic images alignment within the mosaic. Now, a new technology uses both thermal and visible spectrum camera images for alignment is developed. This technology provides high precision of overlap and allows to georeference IR images.

Agisoft PhotoScan photogrammetric processing results in:

  • Visible spectrum orthophoto mosaic generation (GeoTIFF)
  • Thermal images mosaic creation (GeoTIFF)

It is possible to view georeferenced data of thermal survey with Sputnik GIS.

The latest version of Sputnik GIS and a dataset (935 Mb) are available to download.
