Digital Orthophotos

As of 2000, digital orthophoto flights were last done in 1997. Orhophotos and parcel data were done by ATD. The entire county was flown at '400 scale. Developed areas were flown at 200' and 100' foot scale. The original data is in BIL format data is available on 17 CD-ROMs. MrSID compressed versions (10:1) are available as individual files and as mosaics. Data availability by image resolution is shown below:

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/Chatham_County/2000/Vector/Disk3/ (data in State Plane 1983/feet).
