The orthoimagery provided is 4-band (R, G, B, NIR), 8-bit per pixel and delivered in uncompressed TIFF/TFW format and compressed 3-band (R, G, B) MrSID mosaics (20:1, Gen3). The data was flown between April 27th and May 12th, 2025 at an altitude of 15700 feet (AMSL) using an UltraCam Osprey M3 camera and complies with the American Society for Photogrammetry and Remote Sensing Accuracy Standards (ASPRS) for Class 1, large scale maps at 1" = 50'. This orthoimagery is published in Michigan South State Plane, NAD83, International foot.</span></span></p>
