Definition: Tile

Category: UN - Geographic Information Systems

In GIS, a term sometimes used to refer to adjacent digital map sheets that are stored in separate files. Tiles can be of regular shape (e.g., square or rectangular) or they can follow irregular boundaries, such as district or province borders. Storing all tiles in the same geographic reference system allows temporary or permanent joining of adjacent tiles. http://ec.europa.eu/eurostat/ramon/statmanuals/files/Handbook_Geo_Infrastr_Supp_Census_Activ.pdf
