The final ground resolution of the digital orthoimagery shall be six inches per pixel and delivered in uncompressed TIF/TFW format. LiDAR deliverables will include a classified point cloud delivered in LAS specification 1.4-R15 format and a LiDAR derived DEM for orthorectification, delivered in TIF or similar raster format.
