USGS_EROS_Ortho_SCALE service contains orthorectified digital aerial photographs and satellite imagery that are commonly referred to as orthoimagery. The imagery in this service is derived from high resolution images that combine the visual attributes of an aerial photograph with the spatial accuracy and geometric characteristics of a map. The resolution is primarily 1-meter, and the source imagery is acquired through partnerships with U.S. Department of Agriculture’s Farm Service Agency and other cooperating Federal, State, and local agencies. One meter resolution imagery means that each pixel in the orthoimage covers one meter on the earth’s surface. TNM_Large_Scale_Imagery service data is viewed at scales of...

The USGS NAIP Plus service from The National Map consists of National Agriculture Imagery Program (NAIP) and high resolution orthoimagery (HRO) that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a map. Digital orthoimage resolution may vary from 6 inches to 1 meter. In the former resolution, every pixel in an orthoimage covers a six inch square of the earth’s surface, while in the latter resolution, each pixel represents a one meter square. Many states contribute orthoimagery to The National Map, and the USGS also relies on a partnership with the U.S. Department of Agriculture's Farm Service Agency. The National Map download client allows free downloads of public...

These data are spatial polygon data and remote sensing image-based classification maps of surface water and vegetation species for 2012 along the Rio Grande River in Big Bend National Park in Texas. The geographic extent of the classification spans from the end of Mariscal Canyon to 5 km after the end of Boquillas Canyon, totaling approximately 77 Km of the river. The maps are also restricted to a digitized extent of riparian vegetation that is defined by the alluvial valley of the Rio Grande River. The 2012 classification maps are created using 20 cm multispectral (Near Infrared (NIR), Red and Green) imagery and LiDAR data collected in June 2012. The accuracy assessment for the classification product is based on...

NAIP horizontal accuracy specifications - From 2003 to 2004 the specifications were as follows: 1-meter Ground Sample Distance (GSD) imagery was to match within 3-meters, and 2-meter GSD to match within 20 meters of reference imagery. For 2005 the 1-meter GSD specification was changed to 5 meters matching to reference imagery. In 2006, all states used the same specifications as 2005 except for Utah, which required a match of +/- 6 meters to true ground. In 2007, all specifications were the same as 2006, except for Arizona, which used true ground specifications. In 2008 approximately half of the states acquired used true ground specifications and the other half used reference imagery. The 2008 states that used absolute...
As one of the cornerstones of the U.S. Geological Survey's (USGS) National Geospatial Program, The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data. The geographic information available from The National Map includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover.

The USGS NAIP Imagery service from The National Map (TNM) consists of high resolution images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a map. Resolution of National Agriculture Imagery Program (NAIP) data is 1 meter, which means that every pixel in the digital orthoimage covers a one meter square of the earth’s surface. Many states contribute orthoimagery to The National Map, and USGS relies on a partnership with the U.S. Department of Agriculture’s Farm Service Agency for NAIP data. The USGS NAIP Imagery service is a mosaic of 1 meter resolution natural color and color infrared aerial imagery, containing NAIP and other imagery sources to complete the...
