Orthophoto Generation
Seamless colour-balanced mosaics, including true-ortho with building lean removed.
Orthophoto Generation
An orthophoto is judged on the things that are easy to see: whether roads line up across seamlines, whether buildings lean, whether one tile is noticeably bluer than its neighbour, whether shadows and moving vehicles have been cut through awkwardly. Users forgive geometric error more readily than visible seams.
We produce orthophotos with attention to both. Rectification uses the edited terrain model, and for true-ortho a DSM so building lean is genuinely removed rather than merely reduced. Seamlines are placed to follow features and avoid structures, not left on the automatic solution. Colour and radiometric balancing is applied across the whole block so it reads as one capture.
Delivered as tiles on your grid, or as a seamless mosaic dataset with the tiling and compression your systems actually want, plus web-ready pyramids where the imagery is going onto a map service.
