Digital Orthophotos

As of 2000, digital orthophoto flights had been flown between 1993 and 1996. The original data is in BIL format (scanned from hard copy) but is not available. MrSID compressed versions (13:1 compression) are, however, available on CD-ROM. Data are available at 100', 200' and 400' scale resolutions, with higher resolution data in urban areas. Because of scanning and compression the data is not as high quality as the original photography. Data availability by image resolution is shown below:

Onslow Low Resolution Orthophotos

Image index shapefiles (index100.shp, index200.shp, and index400.shp) for each resolution are available on the Geodata server at http://geodata.lib.ncsu.edu/localgov/Onslow_County/2000/meta/ (data in State Plane 1983/feet).
