What is the minimum building size?
All buildings over 100 square feet have been digitized.
What is the minimum parking lot size?
All visible paved parking lots with at least 5 cars have been digitized. No gravel or dirt parking lots will be digitized.
What method is used to digitize?
Heads-up digitizing, in which lines are traced by hand directly on the computer screen using the digital orthoimage as a backdrop, was used in conjunction with the 2007 digital orthoimagery.
What is the accuracy ?
The accuracy of all digitized features matches the accuracy of the aerial photography used. Aerial photography from NCTCOG meets National Map Accuracy Standards at a map scale of 1 inch = 200 feet (1:2400). The photo scale is 1' = 1500' (1:18000).
Any control that was generated in the process of producing aerial photography will be made available to the vendor.
