Summary
"USDA has purchased an Enterprise Premium license for this Orthoimagery/Geo product from DigitalGlobe, Inc. Any government, education, not-for-profit agency and public/individuals not engaged in using the "Product for Commercial Exploitation or Commercial Purposes" can use this licensed data. Use of this product for Commercial Purposes by a person/company/organization for a profit or fee is strictly prohibited. Please refer to the separately attached license from DigitalGlobe, Inc. for additional information. This specific imagery was not Orthorectified due to a lack of a usable DEM at the time this image was requested. This Image was processed as a "Geo"or Georeferenced product from DigitalGlobe." 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. The design accuracy is estimated not to exceed 10-meters. Data received at Earth Resources Observation and Science Center (EROS) were verified as: Projection: WGS_1984_UTM_Zone_55N Resolution: 0.6000 m Type: Natural Color and resampled to align to the U.S. National Grid (USNG). The naming convention is based on the U.S. National Grid (USNG), taking the coordinates of the SW corner of the orthoimage. The metadata were imported and updated for display through The National Map at Chip-level metadata are provided in HTML and XML format. Data were compressed utilizing IAS software. The compression was JPEG2000 Lossy Compressed. The file format created was .jp2.
"DG satellite imagery serves a variety of purposes, from interim maps to field references for geographic information system and as a tool for revision of digital line graphs and topographic maps." 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.
