GDAL WKT Raster driver documentation

1 - Introduction

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

This driver was developed during the ​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.
