U.S. Geological Survey, 2011, USGS High Resolution Orthoimagery for Nassau County, Florida: 17RLP990870_200801_0x3000m_CL_1: U.S. Geological Survey: Sioux Falls, SD,,,


"This dataset is a collection of GeoTIFF and MrSID format natural color orthophotos covering Nassau County, Florida.An orthophoto is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientationhave been mathematically removed. Orthophotography combines the image characteristics of a photograph with the geometric qualities of a map.Imagery was acquired for Nassau County at 0.9 foot ground sample distance (GSD) resolution.Flight height maintained during mission was 9,000 feet AGL.The imagery was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post processing.The imagery was captured with 60% forwardlap and 30% sidelap between all [...]

"The goal of this project is to provide the Florida Department of Revenue with current digital orthoimagery of Nassau County, FL." 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.
