A compression technique for raster, grid or image data. Instead of storing each value of adjacent cells that have the same value, the system stores the value and the number of times the value is repeated. Compression will be significant when discrete objects are stored in a raster GIS. http://ec.europa.eu/eurostat/ramon/statmanuals/files/Handbook_Geo_Infrastr_Supp_Census_Activ.pdf
