Gis raster format
WebGeographic phenomena are commonly represented in a raster format in GIS. The raster grid is georeferenced, so that each pixel (commonly called a cell in GIS because the "picture" part of "pixel" is not relevant) represents a square region of geographic space. [10] WebTIFF files are the best choice for importing into image editing applications and are also a common GIS raster data format. However, they cannot be natively viewed by a web browser. TIFFs also support georeferencing information in GeoTIFF tags or in a separate world file for use as raster data.
