    55It allows simple conversion of existing raster maps into directory structure of tiles, which after uploading on a webserver act as a map source for online viewers. A client viewer (typically a web application) is using the same protocol as when querying dynamically generated tiles from TileCache server (protocol TMS).
    … …  
    99Main part of work is in implementation of global profiles in TMS, improvement of the quality of the render of tiles, and rewriting of HTML templates for standard viewers (based on OpenLayers, Google Maps, MS Virtual Earth, ...).
    1010All the changes will be commited to the code of GDAL2Tiles, as well as existing pending  patches #2052 - (JPEG and TIFF tiles support) and #2053 (world files for tiles).
    11 This way the GDAL2Tiles utility will be ready (feature complete) for rewrite into a R/W Driver, which is done in separate SoC Project [http://trac.osgeo.org/gdal/wiki/SoCTMSDriver GDAL TMS Driver]

    16 Right now the GDAL2Tiles utility doesn't support global-profiles from standard TMS. It means static tiles are not overlayable with Google Maps. This is going to change. Support for both global-mercator (based on Google Projection EPSG:900913) and global-geodetic (based on EPSG:4326) will be implemented. Those two

    18 GDAL2Tiles will generate tiles from supplied raster file (GeoTIFF, MrSID, ECW, ... ) with proper georeference headers. Result structure (e.g. directory with tiles, MapResource.xml containing all necessary geo-metadata and optionally an simple HTML viewerers (based on OpenLayers, Google Maps, ...), as well as KML for Google Earth SuperOverlay) can be simply published on any webserver.

    20 Produced tiles can be used as overlay map on top of Google Map tiles or other available map sources. The simple client will allow [http://www.justmagic.com/nz4265.html presentation with overlay like this one].

    32 - Cooperation on HTTP Read driver for TMS tiles in GDAL, which will allow warping of remotely published TMS tiles, and hopefully also allow MapServer act as a WMS proxy for tiles published as static files on a webserver.
     31- Utility Tiles2Tiles which will convert format of tiles between TMS and other formats, like MSR MapCruncher, WorldWind, GeoQuadTree, Zoomify, etc.

    34 - Utility Tiles2Tiles which will convert (mostly by simple rename) tiles beetween TMS and other formats, like MSR MapCruncher, WorldWind, GeoQuadTree, Zoomify, etc.
     33- Cooperation with the second SoC Project, I am especially interested in HTTP Read driver for TMS tiles in GDAL, which will allow warping of remotely published TMS tiles, and hopefully also allow MapServer act as a WMS proxy for tiles published as static files on a webserver.
