- Abstract
- 2005 NAIP imagery for Wisconsin has a 1-meter spatial resolution. There are DOQQ tiles as well as county mosaics (MrSID format) available. Coordinate systems are reflected in the individual dataset titles.[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 or 1/2 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 pixel 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 covers the county extent. Two types of compression may be used for NAIP imagery: MrSID and JPEG 2000. The target value for the compression ratio is 15:1 for the 1 meter imagery and 60:1 for the 1/2 meter imagery.]
- Purpose
- NAIP imagery may be distributed on an interim basis to meet USDA program requirements. The interim product is a compressed county mosaic. Users should be aware that the interim compressed county mosaic may contain defects and have horizontal accuracy less than the specified tolerances. Defective imagery may be replaced within one year of image acquisition date.
- Supplemental Information
- 2005 NAIP imagery for Wisconsin is 1 meter resolution. There are DOQQ tiles as well as county mosaics (MrSID format) available. Coordinate systems are reflected in the individual dataset titles.

- Description
- This Compressed County Mosaic was generated using MrSID Generation Two (MG2) software using a N-level setting of 9 and a target compression ratio of 50:1. All photography was acquired using metric mapping cameras and acompanied by the collection of airborne Global Positioning System (GPS) data. Photography was scanned using Leica Geosystems DSW 500/600 or Z/I Imaging PhotoScan 2002 image scanners at a resolution of approximately 20 micrometers per pixel. All imagery was aerotriangulated in blocks of 200-1,000 photographs using the Z/I Imaging ImageStation Automatic Triangulation (ISAT) software package. Orthorectification was performed with custom software and the USGS National Elevation Dataset was used for the elevation model. Digital orthophotos were radiometrically balanced in groups of 100-500 images using the Inpho OrthoVista product. Custom software automatically generated the MrSID project parameter file to control the insertion of the digital orthophotos in the final mosaic. The ordering scheme of the digital orthophotos is based on a last-in-last-on-top scheme.
