U.S. Geological Survey, and Axis Geospatial, LLC, 2015, USGS High Resolution Orthoimagery for Baltimore, Maryland: 18SUJ645590_201402_0x1500m_4B_1: U.S. Geological Survey: Sioux Falls, SD,,,


"This dataset contains imagery in TIFF format and is supported through the Department of Information Technology for the State of Maryland to provide digital orthoimagery of the 14 counties of the Western Shore of Maryland. The primary goal of this project was to acquire 4-band (RGBIR) 8 bit 6 inch pixel resolution ortho imagery." 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 reprojected [...]

"This imagery was produced for the Department of Information Technology for the State of Maryland." 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.
