 5. '''GDAL2Tiles/MapTiler''': Implementation of the coming [http://www.opengeospatial.org/standards/requests/54 OGC WMTS] standard, implementation of the pixel-precise warping (by warped VRT editing), implementation of the [http://www.maptiler.org/google-maps-overlay-opacity-control/ opacity slider control] as one of the official OpenLayers Addins, direct tiling of global maps into Spherical Mercator from WGS84 ([http://code.google.com/p/maptiler/issues/detail?id=6 bug]), support for JPEG tiles, support for cutline clipping, NODATA transparency, bug-fixing of [http://code.google.com/p/maptiler/issues/list open issues]. Code is going to be submitted into GDAL SVN and MapTiler SVN. Project MapTiler (the GUI for GDAL2Tiles) is going to be published as a stable version 1.0 with all binary installers (Windows/Linux/Mac) and with support for localization. Knowledge: Python, JavaScript, GNU tools, partly C, C++

+6. '''PostGIS / WKT Raster Driver''': Implementation of read-only GDAL [http://gdal.org/gdal_drivertut.html driver] for [http://postgis.refractions.net/support/wiki/index.php?WKTRasterHomePage WKT Raster] extension to [http://postgis.refractions.net/ PostGIS]. The WKT Raster is  ''is an ongoing project aiming at developing raster support in PostGIS (...) goal is to implement the RASTER type as much as possible like the GEOMETRY type is implemented in PostGIS''. [http://mateusz.loskot.net/?p=291 WKT Raster crash course #1] gives detailed overview of the project background. In short, implementation steps will include parsing of [http://svn.osgeo.org/postgis/spike/wktraster/doc/RFC2-WellKnownBinaryFormat WKB format], define specializations of [http://gdal.org/classGDALDataset.html GDALDataset] and [http://gdal.org/classGDALRasterBand.html GDALRasterBand], implement read operations for bands. The idea behind WKT Raster in GSoC 2009 is to deliver a prototype (or proof of concept) that can be used as a base for further development, so only two raster types are considered: 1 band of [http://gdal.org/gdal_8h.html GDT_Byte] (Greyscale), 3 x 1 band of GDT_Byte (RGB). Knowledge: [http://en.wikipedia.org/wiki/Raster_graphics raster] graphics, basic understanding of [http://en.wikipedia.org/wiki/Well_known_binary Well-Known-Binary]-like formats, [http://www.postgresql.org/docs/8.3/static/libpq.html libpq], C (strong), C++ (basic).
