Description:

Abstract:

This image service includes a mosaic of 6522 individual orthoimages georeferenced to the IDTM83 grid.

This data set contains imagery from the National Agricultural Imagery Program (NAIP). NAIP acquired digital ortho imagery of Idaho during the agricultural growing seasons of 2004. NAIP provides a 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 3 meters of reference digital ortho quarter quads (DOQQS) from the National Digital Ortho Program (NDOP). The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 360 meter buffer on all four sides. NAIP quarter quads are rectified to the UTM coordinate system NAD83. NAIP imagery can obtain as much as 10% cloud cover per tile.

Note: not all of the NAIP tiles for Idaho contained the 360 meter buffer on all sides. Some images along the Idaho border contained areas of No Data. All areas of No Data have been removed in the mosaic.

Purpose:

This purpose of this image service is to provide a seamless raster image for Idaho of the 2004 USDA orthoimagery for viewing in a Web browser. Digital orthoimages serve a variety of purposes, from interim maps to field references for earth science investigations and analysis. The imagery is useful as a layer of a geographic information system and as a tool for revision of digital line graphs and topographic maps.
