= '''1 - Introduction''' =

WKT Raster is the project that provides '''raster support on PostGIS'''. 

This driver was developed during the [http://socghop.appspot.com/ Google Summer of Code] 2009. The driver only supports reading of regularly blocked in-db rasters. There are other functionalities under development:
  * Reading of non-regular blocked rasters.
  * Out-db raster support.
  * Create and modify rasters.
  * Integration with the GDAL utility programs.
