USDA-FSA Aerial Photography Field Office. 2005. Aeriial Photography for the Sand Creek Massacre National Historic Site Vegetation Inventory Project
This data set contains imagery from the National Agriculture Imagery Program (NAIP). NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S..A primary goal of the NAIP program is to enable availability of ortho imagery within one year of acquisition. NAIP provides two main products: 1 meter ground sample distance (GSD) orthoimagery rectified to a horizontal accuracy of within +/- 3 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP); and, 2 meter GSDortho imagery rectified to within +/- 10 meters of reference DOQQs. The tiling format of NAIP imagery is based on a 3.75'x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using NAD83. NAIP imagery may contain as much as 10%cloud cover per tile.This file was generated by compressing NAIP quarter quadrangletiles that cover a county. MrSID compression, with mosaicoption, was used. Target values for the compression ratio are (15:1) and compression levels(9) are used. Sand Creek Massacre National Historic Site and environs.
