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

Write an OGC WMS driver, likely somewhat modelled on the WCS driver implementation.
Implement a raster reader/writer for KML.
Implement vector KML reading.
Generally implement new file format drivers for geospatial raster or vector formats not already supported by GDAL/OGR.
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).
Extend the OGR SQL parser to support some OGC SQL spatial function operators.

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)
new feature to Clip by Polygon, as above but use a vector polygon for the selection area(s)

new program: Command Line Helper. A gui to help build a gdal utilities (gdal_translate, gdalwarp, etc.) command line. I'm always getting confused about --config CACHE_MAX and -co compress=somedarnthing and --optfile somethingelse.txt and so on as a lot of them are specific to the output driver being used.
