Digital Image Processing
To be effective in management decisions, a geographic information system requires timely, accurate update of many of its spatial data elements.
Digital image processing techniques play an important role in the analysis of complex problems. These techniques combine the present intensive computer technology with the unique human ability to visualise complexity and to interpret these images.

rectification - The process of eliminating photo scale variations and relief displacement. In digital image processing, it also refers to correcting for geometric distortions, radiometric calibrations, and noise removal.
Resampling - A technique in digital image processing that interpolates pixels in the source data to new locations of transformed pixels, usually coinciding with a georeferenced grid.
