U.S. Geological Survey, and Pictometry International, 2015, USGS High Resolution Orthoimagery for Los Angeles County, California: 11SLT975875_201312_0x2500m_CL_1: U.S. Geological Survey.


"The dataset consists of tiled orthogonal imagery produced from nadir images captured by Pictometry International." 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 atEarth Resources Observation and Science Center (EROS)were reprojected from: Projection: NAD_1983_StatePlane_California_V_FIPS_0405_Feet Resolution: 10 inch Type: Natural Color to: Standard Product Projection: NAD_1983_UTM_Zone_11N Standard Product Resolution: 0.2500 m Rows: 6000 Columns: [...]

"This ortho-mosaic is a visualization product and is not intended or valid for authoritative or definitive use, nor is it suitable for submittal to the USGS for funding reimbursement in such programs." 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.
