+== 2009 Ideas List ==
+
+1. '''KML Driver''': Develop an enhanced KML driver using Google's [http://code.google.com/p/libkml/ libkml] library. A new driver based around Google's reference implementation would fix some limitations in the current driver (no multi-geometries, no KMZ support, etc), make it easier to keep the driver up to date as KML evolves, and should generally make it easier for GDAL software to exchange data with Google Earth. Both OGR (vector) and GDAL (raster) KML drivers could be developed.
+
+2. '''OpenEV2''': [http://openev.sourceforge.net/ OpenEV] is a GUI tool for efficient displaying and analyzing geospatial data formats supported by GDAL/OGR (including GeoTIFF, MrSID, ECW, .. ESRI Shape files, ..), it is able to convert between file formats, reproject, crop, display by OpenGL a 3D terrain based on elevation from DEM files on Linux, Windows and Mac. Have a look at [http://openev.sourceforge.net/index.php?page=screenshots screenshots] or [http://fwtools.maptools.org/ try it]. It has almost finished port to GTK 2.0 and GDAL python-ng which needs a bit of work, packaging and improvement, more info at [http://www.nabble.com/OpenEV2-updated-td21101297.html OpenEV2 updated post]. Knowledge: Python, GNU tools, GTK 2.0, Linux and partly C, C++.
+
+3. '''PNG Driver''': Implement efficient PNG driver using libPNG with support for optimization of PNG images exported by GDAL (info: [http://www.gdal.org/gdal_drivertut.html tutorial] + [http://svn.osgeo.org/gdal/trunk/gdal/frmts/png png driver]). You can reuse existing open-source [http://members.ozemail.com.au/~dekker/NEUQUANT.HTML NeuQuant algorithm] for RGBA and RGB export. [http://members.ozemail.com.au/~dekker/NEUQUANT.HTML NeuQuant] is easy-to-use practical demonstration of power of the Kohonen Neural Networks. It's source code can be included into GDAL from [http://members.ozemail.com.au/~dekker/NEUQUANT.C original implementation of the algorithm] and/or from [http://pngnq.sourceforge.net/ pngnq utility]. There are also other open-source tools implementing optimization of PNG which can be reused ([http://advancemame.sourceforge.net/doc-advpng.html AdvPNG], [http://optipng.sourceforge.net/ OptiPNG], [http://pmt.sourceforge.net/pngcrush/ PNGcrush]) or can be a source of inspiration ([http://www.advsys.net/ken/util/pngout.htm PNGOut]). Result should be an improved PNG driver for GDAL together with color quantization functions which will produce png files with optimized file-size. Knowledge: C, C++
