2015 NPS-LCR (Digital Orthophotography for the Lower Colorado River)
The 2015 NPS-LCR (Digital Orthophotography for the Lower Colorado River, Eastern Utah) vertical orthophoto, color 4-band aerial project was acquired by the National Park Service (NPS), the Utah Division of Forestry, Fire, and State Lands (FFSL), and the Utah Geological Survey (UGS). The project consists of 15 cm (5.9 in) pixel resolution, 4-band orthoimages covering the lower reaches of the Colorado River in Utah. The design accuracy is estimated to not exceed 21 cm (8.3 in) RMSE. Each orthoimage provides imagery over a 1050 x 1050 meter block on the ground with no image overlap.
