[SoC] GSoC 2014 Weekly Report 10 : GDAL PostGIS Raster driver

[Varun Saraf]

 Hi,

Below is my tenth weekly report.

*What did I do this week?*

   -
   - Inserted an empty raster in the table via
   PostGISRasterDataset::Create().
   - On subsequent PostGISRasterRasterBand::IRasterIO calls, the default
   implementation of GDALRasterBand::IRasterIO is called which in turn calls
   PostGISRasterRasterBand::IWriteBlock with data pertaining to each block.
   - In IWriteBlock, first a new band was added if required and then
   updated the band with input data.
   - Handled datatype translation from GDAL to PostGIS via
   TranslateDataTypeGDALtoPostGIS.

*What do I plan on doing next week?*

   - Testing and bug fixing.

*Am I blocked on anything?*

   - No.
