Abstract:

This is an ArcGIS Server Image Service that provides a three-band natural color image of the 2005 National Agricultural Imagery Program (NAIP) orthorectified digital aerial photos of Montana.

The 1 meter ground sample distance (GSD) ortho images were rectified to a horizontal accuracy of within /- 5 meters of reference digital ortho quarter quads (DOQQs) from the National Digital Ortho Program (NDOP).

Services available include: ArcGIS Server Image services, Open Geospatial Consortium, Inc. (OGC) web coverage services (WCS), and OGC web map services (WMS). The image and web coverage services provide users direct access to the native GeoTIFF files and pixel data for geoprocessing and image analysis. The original GeoTIFF files are available by request from the State Library.

WMS: https://gisservicemt.gov/arcgis/rest/services/MSDI_Framework/NAIP_2005/ImageServer/WMSServer

An Esri shapefile of the dates the images were collected is available at https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2005_NAIP/NAIP_2005_Color_Dates.zip.

The State Library also provides the 2005 NAIP as downloadable natural-color Compressed County Mosaics (CCMs) and as 12-kilometer blocks from the Montana State Library at http://geoinfo.msl.mt.gov/data/Aerial_Photos/NAIP_2005.

Data Quality Information:

Completeness report:

There are small areas along the U.S.-Canada border that are not contained in this dataset.

Horizontal Positional Accuracy Report:

Accuracy is compliant with FSA Digital Orthophoto Specifications. This accuracy standard for the 1-meter orthorectified images requires that 90% of all well-defined points tested must fall within five (5) meters of the same location identified on Government furnished baseline orthophoto control imagery.
