| 14 | 14 | Orthorectification is the process of removing the effects of image [wiki:tilt_displacement perspective] (tilt) and [wiki:relief_displacement relief] (terrain) effects for the purpose of creating a planimetrically correct image. The resultant orthorectified image has a constant scale wherein features are represented in their 'true' positions. This allows for the accurate direct measurement of distances, angles, and areas (i.e. mensuration). Orthorectified images are commonly used as in visualization tools such as Google Earth, OSSIM Planet, !ArcMap, WMS, etc. |
