An orthomosaic is a single, geometrically corrected aerial image stitched from hundreds of overlapping drone photos.

An orthomosaic is a single, geometrically corrected aerial image stitched from hundreds of overlapping drone photos. Unlike a raw aerial photo, every pixel sits at its true map coordinates — you can measure distances and areas directly. FI Tech captures orthomosaics weekly across Saudi mega-projects using DJI Matrice 350 RTK drones with 5 cm ground sample distance, processed in Pix4D or Agisoft Metashape. The orthomosaic feeds construction-progress segmentation models, change-detection pipelines, and BIM as-built comparisons. Output formats are GeoTIFF and tiled MBTiles for web viewers, georeferenced to UTM Zone 38N (KSA central) or 39N (KSA east).
