About the Data
A digital orthophoto quarter-quadrangle (DOQQ) is a digital image of an aerial photograph that has been ortho-rectified. DOQQs are 1-meter resolution and covers an area on the ground of 3.75-minutes longitude by 3.75-minutes latitude.
High-resolution imagery is most often 1-foot resolution and covers 5000 feet x 5000 feet on the ground. Occasionally imagery at 1/2-foot or 2-foot resolution is collected. Most counties are flown once every three years as part of a statewide cycle, with the flying season usually running from November through March. This imagery is in State Plane projection and MrSid file format.
