| Typically the quality of the aerial photographs is rated in pixels per cm. The obvious tradeoffs are coverage per image vs. quality. | Typically the quality of the aerial photographs is rated in pixels per cm. The obvious tradeoffs are coverage per image vs. quality. | ||

| + | |||
| + | |||
| + | Square inches/Square pixels = inches per pixel | ||
| + | |||
| + | |||
| + | Ex: Nikon D600 (24mp 6016 x 4016) = 24,160,256 pixels | ||
| + | |||
| + | 50.40 m x 33.6 m = 169,344 sq cm. | ||
| + | |||
| + | 169,344 / 24,160,256 = .007009 m or 7 mm | ||
| + | |||
| + | |||
| + | |||
| + | Nex5 = 4912x3264 resolution or 16,032,768 megapixels | ||
| + | |||
| + | |||
| + | At 150 ft in height | ||
| + | |||
| + | Convert to square centimeters FOV = 31,354,776 sq cm. | ||
| + | |||
| + | 31,354,776 / 16,032,768 = 1.955 cm per pixel | ||
