Description:
Abstract:
This data set contains imagery from the National Agricultural Imagery Program (NAIP). 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 availabilty of ortho imagery within a year of acquisition. NAIP provides two main products: 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); and, 2 meter GSD ortho imagery rectified to within +/- 20 meters of reference DOQQs. 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.
Purpose:
The 1 meter GSD NAIP is intended as a source for current digital ortho imagery in USDA Field Service Center GIS and for other uses that require ortho imagery acquired during the agricultural growing season.

Process_Step:
Process_Description:
Direct digital capture using Leica ADS40 sensors flown on a 5 minute line spacing with 35% lateral overlap at 25,000 feet AMT. Download and imagery QA/QC performed using Leica GPro software suite. GPS/INS processing is performed using Applanix PosPAC version 4.01. This provides both the position and orientation of the sensor during flight. The horizontal accuracy of the ortho- rectified imagery is primarily determined by the quality of the AT solution and the surface model (digital elevation model or DEM). The horizontal control is picked from USDA furnished mosaicked DOQQs (mDOQQs) and vertical control picked from the USGS DTED 2 DEM data. Aerial triangulation was done using either the Leica GPro/ORIMA package or the ISTAR processing package. In both cases automatic generation of image points both along strip and between strips is performed. These points are combined with the manually measured horizontal control and then a bundle adjustment is performed. Orthorectification is performed on the triangulated imagery on a strip-by-strip basis using either Leica GPro or ISTAR processes. These strips are rectified using the USGS DTED 2 DEM data. Once the strips are rectified they are processed in an automatic seam-line generation process to mosaic the imagery together into a seamless product both geometrically and radiometrically. This seamless mosaic is cut into the DOQQ tiles with the 360m buffer. Each DOQQ is inspected for relative horizontal accuracy with adjacent DOQQ tiles. A sample of DOQQs is inspected for relative horizontal accuracy with the USDA furnished mDOQQs. Completed and approved DOQQs are assembled into a countywide MrSID file, using a compression factor of 1:50. The countywide MrSID mosaics are edge-inspected against the prior generation county mosaics to ensure accuracy.
