Orthophoto/True Orthophoto Creation
An orthophoto, orthophotograph or orthoImage is referred as a geometrically corrected or orthorectified aerial photograph or satellite Imagery. It can be considered as an Image representation of a map where the scale is uniform. Unlike an uncorrected aerial photograph, an orthophoto can be used to measure true distances, because it is an accurate representation of the Earth’s surface, having been adjusted for topographic relief, lens distortion, and camera tilt.
The final orthophoto is termed as the mosaic of a series of orthophotos that covers a small or large area of land where all individual orthophotos are feathered / blended together following some seam lines. These seam lines can be generated either automatically or manually. Regardless of how they are created, the seam lines define where in the overlapping zone between two Images the actual division will take place. As a result, automatically generated seam lines need to be checked whether they are crossing a building, structure etc. to ensure a seamless mosaic.
