U.S. Geological Survey, and Surdex Corp, 2015, USGS High Resolution Orthoimagery for Colville Confederated Tribes Reservation, Washington: 11TLP630100_201410_0x3000m_4B_1: U.S. Geological Survey: Sioux Falls, SD,,,


"This data set consists of 0.3-meter pixel resolution (approximately 1-foot), 4-band orthoimages covering the Colville Confederated Tribes Reservation. 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. The design accuracy is estimated not to exceed 1.52-meters NSSDA 95% confidence (0.88-meters Root Mean Squared (RMSE) Error XY (0.62 meter RMSE X or Y). There are 2,635 - 1500-meter by 1500-meter ortho tiles that makes up the project area. Each orthoimage tile provides imagery over a 1500-meter by 1500-meter block [...]

"This orthoimagery depicts geographic features on the surface of the earth in the project area of interest under leaf-off conditions. It was created to provide easily accessible geospatial data which is readily available to enhance the capability of The Colville Confederated Tribes" 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.
