orthophoto mosaic orthophoto mosaicA type of air photo mosaic that is more accurate than controlled or uncontrolled mosaics. The process transforms the air photos into a larger mosaic that has characteristics of a map (true distance, angles, and areas) but can be interpreted like a photograph. The process of conversion is called differential rectification and involves the elimination of photoscale variations and image displacement using an orthophotoscope. |
