Data rectification / geocoding

Data rectification / geocoding Raster data is generally displayed in the form of "raw" data and has a geometric error. To obtain accurate data, the data must be corrected geometrically into the earth coordinate system. There are two geometric correction process: Registration, geometric correction of images that have not been corrected with the image that has been corrected.

Rectification, a geometric correction of images with maps The image mosaic Mosaic image is the process of combining / attaching two or more images that overlap (overlapping) so as to produce a representative image and continuous. ER Mapper in this process can be done without creating a large file, except when we want to keep a separate file.
