Glossary for Geospatial Science

mosaic:  A large image assembled from segments.  Each segment may come from a different source and have a different cell size and angle of orientation, but all the segments must be geometrically rectified and calibrated to a common coordinate framework.  The mosaic process rotates and re-scales each piece and creates a single combined object.  If all segments are georeferenced to the same map projection, they can be automatically mosaicked based upon their geographic calibration without additional adjustments.  Recognized verbal forms of mosaic are mosaic, mosaicked and mosaicking.
