U.S. Geological Survey, and Photo Science, Inc., 2014, USGS High Resolution Orthoimagery for Sarasota County, Florida: 17RLL630045_201401_0x3000m_CL_1: U.S. Geological Survey: Sioux Falls, SD,,,


"The RGB one-foot orthophotos to be mapped consists of 2,663 cells (approximately 2388 square miles) flown with a Z/I Intergraph DMC airborne digital sensor. The flight season was from December 15, 2013 through March 15, 2014. The flight dates are as follows: January 18, 2014; January 19, 2014; January 20, 2014; and January 22, 2008. All images were collected between 10:00 AM to 2:30 PM to minimize shadows." 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 [...]

"The Florida Department of Revenue (FDOR) regularly uses digital orthophotos to support regulatory, land management and acquisition, planning, engineering and habitat restoration projects." 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.
