U.S. Geological Survey, and Ottawa County, 2015, USGS High Resolution Orthoimagery for Eastern Ottawa County, Michigan: 16TEN970550_201404_0x3000m_4B_1: U.S. Geological Survey: Sioux Falls, SD,,,


"This raster dataset consists of 8-bit, 4-band (R, G, B, NIR) color orthoimagery. A digital orthoimage is a raster image processed from vertical aerial images in which displacement in the image due to sensor orientation and terrain relief have been removed. Orthoimagery combines the image characteristics of an image with the geometric qualities of a map. Unlike planimetric maps which depict natural and manmade features by means of lines, point symbols, texts and polygons, orthoimagery illustrates the actual images of features and are thus more easily interpreted than regular maps. The normal orientation of data in an orthoimage is by lines (rows) and samples (columns). Each line contains a series of pixels ordered from west to east [...]

"An orthoimage is useful as a layer of any geographic information system (GIS). It can function as a cartographic base for displaying, generating, and modifying associated digital planimetric data. Other applications include environmental impact assessments, disaster management, emergency evacuation planning, flood analysis, soil erosion assessment, facility management, ground-water and watershed analysis, right of way and road alignment, transportation network inventory and analysis, preliminary design studies, vegetation classification detection of physical features or attributes not possible at ground level, and a myriad of additional applications." 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.
