Digital Orthophoto Quarter Quadrangles for North Dakota. The aerial image files in this archive are copies of standard digital orthophoto quarter quadrangles (DOQQ) received from the Natural Resource and Conservation Service which they obtained from the US Geological Survey. We have also updated the mosaic with DOQQs obtained directly from the USGS. The projection for the mosaic is UTM, NAD83, Zone 14. Dates range from approximately 1995 on the western side of the state thru 1998 on the eastern side of the state. An index is available within the feature class called QuadIndex_Poly. The field within the attribute table which gives the date of photography for any particular quarter-quadrangle is DOQQ_DATE. DOQ images were acquired in native BSQ or TIFF format and either 1) left in UTM, NAD83, Zone 14 format, or 2) reprojected from UTM NAD83 Zone 13 to Zone 14 using ArcInfo Workstation vers. 8.2, 8.3, and 9.0; They were then clipped to USGS 3.75' quarter quadrangles before being mosaiced into state-wide image; Resampling for SDE pyramids was done using bilinear interpolation. The work was done June 2002 thru September 2004Image acquisition scale: 1:40,000 (1"=3,333 feet); Map scale: Meets national map accuracy standards for the scale of 1:12,000 (1"=1000 feet); Accuracy: +/- 33.3 feet; Pixel size: 1 meter x 1 meter.
