Google Summer of Code

GDAL participates in the ​Google Summer of Code under the OSGeo umbrella.

• 2007 Projects

2008 Ideas List

These are suggestions. Students are encouraged to come up with their own ideas as well.

1. Implement GeoPNG/GeoJPEG by embedding 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
   • http://trac.osgeo.org/gdal/ticket/1742 was an attempt to provide georeferencing to PNG, GIF and JPEG datasets. The format itself used lacks standardization, but the mechanisms used can be usefull.

2. ​PNG Driver (using libpng)
   • ​JPEG Driver (using libjpeg)

3. OGR WFS read (or read/write) driver using existing OGR GML driver for feature parsing.
   • ​OGC WFS Specification
   • ​The OpenGIS Web Feature Service (WFS) Implementation Specification
   • ​OGR Driver Tutorial

4. Implementation of alternative driver for GML 2 and GML 3 using ​Expat XML Parser

5. Implementation of read-only WFS driver using GML driver based on the Expat XML Parser.

6. Develop a driver for GeoRSS
   • ​GeoRSS specification

7. Develop a driver for ​OpenStreetMap protocol
   • ​OSM Protocol Stack

8. Develop a driver for IBM DB2 and its Spatial Extender
   • ​DB2 Spatial Extender

9. Extend ​GeoJSON driver with cashing capabilities when accessing remote datasource.
