The NAIP imagery is available for distribution within 60 days of the end of a flying season and is intended to provide current information of agricultural conditions in support of USDA farm programs. For USDA Farm Service Agency, the 1 meter GSD product provides an ortho image base for Common Land Unit boundaries and other data sets. The NAIP imagery is generally acquired in projects covering full states in cooperation with state government and other federal agencies who use the imagery for a variety of purposes including land use planning and natural resource assessment. The NAIP is also used for disaster response often providing the most current pre-event imagery.
This web mapping service (WMS) provides the 2009 NAIP data for the State of Maine in a single seamless mosaic. This WMS is provided by the Maine Office of GIS and the Maine GeoLibrary. This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to enable availability of ortho imagery within one year of acquisition. The NAIP provides two main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy within +/- 5 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP) or from the National Agriculture Imagery Program (NAIP); 1 meter GSD ortho imagery rectified within +/- 6 meters to true ground. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. The NAIP imagery is formatted to the UTM coordinate system using the North American Datum of 1983 (NAD83). The NAIP imagery may contain as much as 10% cloud cover per tile. This file was generated by compressing NAIP imagery that cover the county extent. Two types of compression may be used for NAIP imagery: MrSID and JPEG 2000. Target value for the compression ratio is (15:1).
There are no credits for this item.
None, The USDA-FSA Aerial Photography Field Office asks to be credited in derived products. If defects are found in the NAIP imagery during the warranty period such as horizontal offsets, replacement imagery may be provided. Imagery containing defects that require the acquisition of new imagery, such as excessive cloud cover, specular reflectance, etc., will not be replaced within a NAIP project year.

Aerial photography was acquired using a frame based digital camera (UltraCamD (UCD), UltraCamX (UCX), or DMC), therefore no scanning conversion from film to digital was needed. Geometric and radiometric calibration for each one of the camera heads is determined in the manufacturing laboratory. This step is also known as geometric and radiometric calibration of a single camera head and done when the sensor is being manufactured. The 4 multispectral heads collect 4 separated bands: Red, Green, Blue and Near Infrared wavelength. Both the UltraCam and DMC sensors collect 12bit data. The UCD sensor CCD pixel size is 9 micron with a footprint of 7500 pixels in the long track, and 11500 pixels in the cross track. The UCX sensor CCD pixel size is 7.2 micron with a footprint of 9420 pixels in the long track, and 14430 pixels in the cross track. The DMC sensor CCD pixel size is 12 micron with a footprint of 7680 pixels in the long track, and 13824 pixels in the cross track. Twin Engine Navajo, Turbo Commander and Conquest aircrafts were used, flying at average flight height of 6,700 to 8,600 meters above ground, allowing image acquisition of 0.67 to 0.86 meters Ground Sample Distance. An INS - Inertial Navigation System, with AGPS (Airborne GPS) and IMU (Inertial Measurement Unit) was utilized for all aerial missions. The INS allows for accurate photo-center registration and image orientation. For inspection and verification of accuracy of the exterior orientation computed with the Inertial Navigation System, stereo compilation was performed for every flight mission and its result compared against higher accuracy source data. If a test of positional accuracy failed (> 5 meters) a full analytical triangulation is processed for that mission, assuring accurate horizontal positioning. USGS seamless NED data was used as a surface for ortho-rectification. Sanborn used proprietary software called METRO to rectify the scanned images. Rectification was done using cubic convoluti

The Maine Office of GIS and the GeoLibrary Board provide web mapping services to distribute aerial photos and other digital data. A WMS is not a web application which you can see in a web browser; rather, it requires you to add the service to a GIS software application.
