U.S. Geological Survey, and Grand Traverse County, MI, 2014, USGS High Resolution Orthoimagery for Grand Traverse County, Michigan: 16TFQ270455_200604_0x6000m_BW_1: U.S. Geological Survey: Sioux Falls, SD,,,


"This data set consists of 2-foot pixel resolution black and white orthoimages covering the county footprint. 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. Each orthoimage provides imagery over a measured 4074-foot by 4106-foot block on the ground. There is no image overlap between adjacent files. The projected coordinate system is Michigan Central with a NAD83 datum."Data received at Earth Resources Observation and Science Center (EROS) were reprojected from:Projection: NAD_1983_Michigan_GeoRef_MetersResolution: [...]

"This data depicts geographic features on the surface of the earth. It was created to provide easily accessible geospatial data which is readily available to enhance the capability of Federal, State, and local emergency responders, as well as plan for homeland security efforts. This data also supports The National Map." 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.
