Abstract:
This is an ArcGIS Server Image Service of the 4-band 2011 National Agricultural Imagery Program (NAIP) orthorectified digital aerial photos of Montana. The one-meter ground sample distance (GSD) ortho images were rectified to a horizontal accuracy that matches within six meters of photo-identifiable ground control points, which are used during image inspection. NAIP imagery may contain as much as 10% cloud cover per tile.

The data were created for the U.S. Farm Services Agency National Agricultural Imagery Program (http://www.apfo.usda.gov) by Surdex Corporation. A version of the data in Montana State Plane Coordinates (NAD83 High Accuracy Reference Network, meters) was provided to the State Library as a collection of seamless 4-band GeoTIFF images.

The web 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. An Esri shapefile of the dates the images were collected is available at
https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Imagery/2011_NAIP/24_km_tiles/00_NAIP_2011_Dates.zip.

Imagery defaults to natural color. To view the imagery as false-color infrared (CIR), select band 4 as the red image, band 1 as the green, and band 2 as the blue.

The data are also available for download in MrSID format from the State Library at http://geoinfo.msl.mt.gov/data/Aerial_Photos/NAIP_2011
Purpose:
These aerial photographs were captured to support various governmental, municipal, tribal, and emergency management Geographic Information System activities. Orthorectified aerial photographs can be used to determine the geographic location of objects visible on the photos.
