Project specifications are based on the American Society of Photogrammetry and Remote Sensing (ASPRS) standards. The data were developed based on a horizontal projection/datum of NAD 1983 2011 StatePlane Massachusetts Mnld FIPS 2001 FtUS, Foot US. Imagery data were delivered as 0.25 foot 8-bit 4-band (RGB-IR) GeoTIFF tiles and 8-bit 4-band (RGB-IR) MrSID mosaics (20:1 compression ratio). Tiled deliverables contained 53 individual 2640 ft x 2640 ft tiles.</SPAN></P><P><SPAN> Ground Conditions: Imagery was collected in spring 2021, while no snow was on the ground and rivers were at or below normal levels.</SPAN></P></DIV></DIV> |
