U.S. Geological Survey, and Woolpert, Inc., 2014, USGS High Resolution Orthoimagery for Colorado Springs, Colorado: 13SED160140_201404_0x1500m_CL_1: U.S. Geological Survey: Sioux Falls, SD,,,


"TASK NAME: United States Air Force Academy (USAFA) - 133UA OrthoAerial Imagery Acquisition and Digital Orthophoto Production TaskUSGS CONTRACT NO: G10PC00057TASK ORDER NO: G13PD00927CONTRACTOR: Woolpert Inc." An orthoimage is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. There is no image overlap between adjacent files.Data received at Earth Resources Observation and Science Center (EROS) were verified as:Projection: NAD_1983_UTM_Zone_13NResolution: 0.1500 mType: Natural Colorand resampled to align to the U.S. National Grid [...]

"This task consists of color digital aerial imagery acquisition and color digital orthophoto production at 0.15 meters ground sample distance (GSD) for approximately 56 square miles of the United States Air Force Academy (USAFA). The aerial photography plan and the 750 meter x 750 meter digital orthophoto tiles were based on the U.S. National Grid. The final product consisted of 302 color digital orthophoto tiles at a 0.15 meter pixel in TIFF format with ASCII TFW file." A digital orthoimage is a geometrically accurate photographic record of landscape conditions at the time of the corresponding aerial photography. As such, High Resolution Orthoimagery is useful for a variety of applications, such as environmental monitoring, facility engineering/maintenance, city/county planning, property line review, etc. The digital orthoimage can be used alone or as a raster basemap for corresponding vector line mapping. The detailed focus of High Resolution Orthoimagery provides emergency responders critical information in determining the best evacuation routes, alternative routes and safe access to aid. High Resolution Orthoimagery assists law enforcement personnel in determining the best locations to place surveillance cameras in high-traffic urban areas and popular attractions. The data assists Federal, State and local emergency responders in planning for homeland security efforts. This data also supports The National Map.
