Unlike an uncorrected aerial photograph, an <br />orthophotograph can be used to measure true distances, because it is an accurate representation of <br />the Earth's surface, having been adjusted for topographic relief, lens distortion, and camera tilt. <br />Orthophotos generally come in six (6) inch, four (4) inch, and three (3) inch resolutions; the smaller <br />the inch measurement, the higher the resolution. <br />Oblique Imagery is aerial photography that is captured at approximately a 45 degree angle with the <br />ground. The angle allows viewers to see and measure not only the top of objects but the sides as <br />29 -1 <br />
