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 of ortho imagery within one year of acquisition. NAIP provides four main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 5 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP); 2 meter GSD ortho imagery rectified to within +/- 10 meters of reference DOQQs; 1 meter GSD ortho imagery rectified to within +/- 6 meters to true ground; and, 2 meter GSD ortho imagery rectified to within +/- 10 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. NAIP quarter quads are formatted to the UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile. Purpose: 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 1 meter 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. With an annual cycle, NAIP is also used for disaster response often providing the most current pre-event imagery. While suitable for a variety of uses the 2 meter GSD NAIP imagery is primarily intended to assess crop condition and compliance to USDA farm program conditions. The 2 meter imagery is generally acquired only for agricultural areas within state projects.

Use_Constraints: Imagery may be replaced to address defects found in a small number of products through quality assurance processes. 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.

Process_Step: Process_Description: Digital frames captured with a ZI Intergraph DMC with a footprint of 7680 x 13824 pixels were used to create Digital Orthophoto Quarter Quadrangles. DMC Serial Numbers 006, 040, 126 and 151 installed in a Rockwell Turbo Commander 690, Piper Cheyenne 2, Rockwell Turbo Commander 690, and Piper Navajo; N57175, N400CM, N167R, N73TM were used to fly. Calibration reports are on file with the USDA. 12 micron frames were captured at eight bits with 2.5 - 2.7 foot pixel using Windows Server 2003; ZI Mission Planning 1.3; Intergraph GeoMedia 6.0; DMC Image Analyst 5.2; DMC Post Processing 6.1; ZI Image Viewer 1.0; Microsoft Access; Microsoft Excel; Flight ASL was 27,500 feet. The state was flown in blocks for efficiency of capture and in order to accommodate the different elevations throughout the state. Flight planning software includes TopoFlight 7.0.9; ZI Inflight 1.3; ZI Imageview 1.2; ArcView 9.3.1; Microsoft Access; and POSAV 2.1. Ground control points were gathered from previous in-state projects. External Orientation files created from ABGPS data in Applanix POSPac MMS Version 5.2 and are rectified using Mortho (Aero Metric propietary software). Extensive Quality Control checks are performed on the data throughout the production process. Processed RAW Frames are checked for spectral compliance. Rectified frames are checked for spatial accuracy and also spectral compliance. DOQQs are thoroughly checked for spectral and spatial accuracy in Iras/C and Adobe PhotoShop. CCMs are checked for overall spectral compliance and spatial accuracy in ArcGIS. Seamline shapefiles are checked for gaps, slivers, overlaps and multipart features by building a toplogy in ArcGIS. Ground control points are read off of rectified frames as a double-check and final DOQQs are used to calculate RMSE values in MicroStation and Excel. Frames are rectified with 30 meter NED in Intergraph OrthoPro. No significant DEM errors were encountered. This surface is checked for errors at the mosaicked DOQQ level. If any areas presented problems, they are noted in a Digital Elevation Model Errors ASCII text file.
