GDAL SoC Ideas

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.
   • WMS Specification
   • WCS Code
   • GDAL Raster Driver Tutorial
2. Extend the existing KML vector feature writer to also support reading KML, and otherwise generalize this driver.
   • writer code
   • driver docs
   • OGR Driver Tutorial
3. Implement a raster reader/writer for KML.
   • KML Docs
   • GDAL Raster Driver Tutorial
4. Generally implement new file format drivers for geospatial raster or vector formats not already supported by GDAL/OGR. GDAL Raster Driver Tutorial, OGR Driver Tutorial, Existing Raster Formats, Existing Vector Formats
5. 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).
   • GMLJP2 Specification
   • GMLJP2 Code: gdaljp2metadata.cpp gdalgmlcoverage.cpp
   • PNG Driver (using libpng)
   • JPEG Driver (using libjpeg)
6. New feature Clip to Extents of other raster, paying attention to nodata (take Raster A, and clip out/erase all areas for which Raster B does not extend to or has nodata values)
   • Utilize the rasterization algorithm that is part of gdal_rasterize.cpp
7. New feature to Clip by Polygon, as above but use a vector polygon for the selection area(s)
   • Utilize the rasterization algorithm that is part of gdal_rasterize.cpp
8. OGR WFS read driver using existing OGR GML driver for feature parsing.
   • OGC WFS Specification
9. 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
