Glossary for Geospatial Science

tiles:� Rectangular areas of defined size in a raster object used for storage of the information.� Storing raster objects in tiled format generally increases display speed when viewing less than the entire object.

Also, raster object image segments that are assembled and trimmed in the TNTmips mosaic process.�

A third usage of the word tiles occurs in the Color Map Editor where the upper part of the window displays the colors in the map with small sample squares, or tiles.� The active or selected tile is outlined in white, and its cell value and a larger sample is displayed below.
