Aerial Photogrammetry Equipment

Orthoimagery draped over a DEM generated from aerial photgrammetric processing. The area shown is Mullaghfarna, Co. Sligo. The Discovery Programme has PCI Geomatica 10.0 software, which contains the Orthoengine photogrammetric processing module. This allows the processing of images stage by stage to extract the DEM and use it to create the ortho-rectified images, which are mosaiced to produce orthophoto maps.
