Size of raster data in geographic information systems (GIS) can be measured in gigabytes, sometimes even in terabytes.
Because of that amount of data it is needed to choose suitable ways for raster data storage and processing. First way is to store raster data directly to the file system in different file formats and process them with separate tools. On the other side raster data can be stored in database and be processed with functions and procedures. This paper will compare these two approaches for raster processing through the use of GDAL tools and Oracle 12c Spatial and Graph GeoRaster functions and procedures.
