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.

10. Development of Java bindings.

11. GDAL/OGR for Windows CE: porting new drivers

12. Development of ​C# language ​SWIG bindings for ​.NET Compact Framework and creating test applications for it.

13. Creating an ASP.NET multithreading testbed for the GDAL C# bindings, by using the ​thread pool approach.

14. Development of bindings for new programming languages: ​Lua, ​Ada (​GNAT), put your favorite language here

15. Development of GDAL Read/Write Driver for tiles, derived from ​GDAL2Tiles utility.

16. GDAL2Tiles - support for TMS tiles with global-mercator profile to make overlays with Google Maps, MS Virtual Earth, etc. possible.

17. Extend the HDF5 driver to support writing datasets. This should include an effort to produce HDF5 datasets according to NASA HDF5 metadata conventions where possible. HDF5 is a new generation format expected to be widely used for science data products from NASA and other agencies.

18. GDAL_CALC.PY - Development of a simple raster calculator based on Python+GDAL. Use sample:

% gdal_calc a=img1.tif b=img2.tif c=img3.tif -calc c=((a+b)/2)
