For 2008, GDAL ideas are in the GDAL Trac Wiki.

GDAL/OGR Related ideas for the Google Summer of Code 2007:

  1. Write an OGC WMS (Web Map Service) driver, likely somewhat modelled on the WCS driver implementation.
  2. Extend the existing KML vector feature writer to also support reading KML, and otherwise generalize this driver.
  3. Implement a raster reader/writer for KML. -- More info in GDAL2Tiles SoC 2007
  4. Implement GeoPNG/GeoJPEG by embeding coordinate system and geotransformation information (possibly in GML) as chunks in PNG and JPEG files (see GML JP2 for a model of how this might be done).
  5. OGR WFS read driver using existing OGR GML driver for feature parsing.
  6. Design a SAR (Synthetic Aperture RADAR) "Processor" using GDAL as a data reader/processed data writer
    • Provide enhancements to relevant drivers (and potentially write new drivers) for reading new/common unprocessed SAR data sources, including metadata support where needed
    • Implement an end-to-end Range-Doppler Algorithm processor for platforms where processing details are available
    • more SAR Processor details
  7. Develop a driver for GeoRSS
  8. Complete C# bindings with gdal_warp api support
