     22 * '''is as simple as PostGIS...'''
     23  * one table = one raster coverage (like a vector coverage)
     24  * one row = one tile or one raster object (like a vector coverage where one row = one geometry)
     25  * only one new type: RASTER (like the PostGIS GEOMETRY type)
     26  * each raster tile has a pixel size, a width and a height, a variable number of band, a pixel type per band and a nodata value per band. Everything essential to do base raster GIS operations.
