libxml2

 * XML read/write library

msvcrt

 * Various Microsoft Visual Studio C runtimes (VC6, VC7.1, VC8.0).
 * No source available, but they are redistributable.
 * Required most visual studio built packages.
 * It might make sense to refactor this into specific 7.1, and 8.0 packages, and possibly remove MSVCRT.DLL which I think is available on all win32 systems already.
 * Maintained by FrankW

mysql

 * MySQL client access library
 * Actual package is called libmysql
 * Required by GDAL (MapServer?)
 * Maintained by FrankW (Derived from BuildKit)

NetCDF

 * NetCDF file format reading and writing library
 * Package includes library and a few executables (ncdump, etc)
 * Required by GDAL
 * Maintained by FrankW (derived from BuildKit)

sqlite3

 * SQLite3 database access library and sql engine.
 * Includes library and commandline sqlite3 command.
 * Required by GDAL, GRASS

xerces-c

 * XML Parser
 * Required by GDAL
 * Maintained by FrankW (derived from BuildKit)

zlib

 * Deflate compression/decompression library
 * Required by GDAL, libtiff
 * Maintained by FrankW

libpq

 * PostgreSQL client access library
 * Required by GDAL, GRASS, MapServer
 * Maintained by FrankW (derived from BuildKit)

proj

 * Coordinate system transformation library
 * Includes commandline tools (proj, cs2cs, geod)
 * Currently lacks some datum shift files. Perhaps some supporting datum shift data should be a separate package?
 * Required by GDAL, GRASS, MapServer
 * Maintained by FrankW

Tcl/Tk

 * Required by GRASS
 * Normally done using ActiveState Tcl but this has license restrictions on redistributions. Not sure what our options are on this.
 * Not yet packaged, no maintainer.

Qt4

 * Required by QGIS and OSSIM
 * Not yet packaged, no maintainer.
 * Has been packaged by Tisham Dhar for QGIS win32 releases.

Script Languages

 * see Tcl/Tk in the GUI Library group - mostly needed for GUI scriptinin in GRASS.

perl

 * Required for Geoinformatica
 * Perl bindings also exist for MapServer and GDAL
 * Perl, built with MinGW, an example is Strawberry Perl but the compilation is not a problem
 * Not packaged and no maintainer (but Ari Jolma might well take this on)

gdal

 * Raster / Vector format geospatial data access library
 * Currently all one package including commands, python scripts, etc. Should likely factor into a -lib, -bin and -python set of components and a meta package for all of them.
 * Python stuff not working yet.
 * Should add C#, Perl, Java and perhaps Ruby bindings.
 * Lots of extra formats ought to be added, including HDF4, OGDI, JasPer (maybe), ecw (nonfree), mrsid (nonfree),, dods/OPeNDAP, SDE (nonfree)
 * Required by MapServer, GRASS, OSSIM, QGIS
 * Requires libtiff, libjpeg, libgeotiff, proj, hdf5 curl geos libmysql sqlite3 netcdf libpq expat xerces-c
 * Maintainer is FrankW

gdal-oracle10g

 * Vector plugin for Oracle 10g (requires user supplied OCI.DLL normally from oracle instant client).
 * Requires gdal
 * Maintainer is FrankW (actually built by HowardB)

gdal-sde90

 * Vector/Raster plugin for SDE 9.0 (requires user supplied ESRI SDE libraries).
 * Requires gdal
 * Maintainer is FrankW (actually built by HowardB)

gdal-sde91

 * Vector/Raster plugin for SDE 9.1 (requires user supplied ESRI SDE libraries).
 * Requires gdal
 * Maintainer is FrankW (actually built by HowardB)

gdal-sde92

 * Vector/Raster plugin for SDE 9.2 (requires user supplied ESRI SDE libraries).
 * Requires gdal
 * Maintainer is FrankW (actually built by HowardB)

mapserver

 * Web Map Server with support for various OGC protocols such as WMS, WCS, WFS and SOS.
 * Version string: "MapServer version 5.0.2 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE"
 * Several libraries (ie. AGG, ming(swf), freetype) are statically linked in but really should be factored out as dlls in distinct packages.
 * Current package is just the cgi and utility executables.
 * Needs bindings packages for php, perl, python, java and c#.
 * Requires: curl geos libpq gdal proj iconv fcgi libxml2
 * Maintained by FrankW

QGIS

 * A desktop QIS
 * Requires GDAL, Qt4, ...
 * Tisham Dhar (what_nick)'s win32 builds are done using MinGW/MSYS and with some effort may be repurposed.
 * FrankW taking action to migrate QGIS from GDAL/OGR C++ API to GDAL/OGR C API to avoid MinGW/VC++ DLL sharing problems.
 * Not packaged, no maintainer (Tisham Dhar likely candidate)

GRASS

 * A commandline and desktop raster/vector GIS system.
 * requires GDAL, Tcl/Tk (for GUI) and several other packages...
 * Details on WinGRASS at: http://grass.gdf-hannover.de/wiki/WinGRASS_Current_Status
 * Currently not packaged and no maintainer.
 * We likely want to distribute with MSYS package for commandline operations though I believe the WinGRASS objective is to not require this.
 * WinGRASS is built with MSYS/MinGW currently. Some care will be required with supporting packages (ie. GDAL) to ensure they can be practically used from the MSYS/MinGW environment.

Geoinformatica

 * GTK+, for example the one from Glade for Windows works
 * Perl, built with MinGW, an example is Strawberry Perl but the compilation is not a problem
 * A long list of Perl modules including GTK2 and Cairo
 * GDAL and GDAL-Perl, built with MinGW and MSYS (I'm not sure if it's a requirement that GDAL has to be built with MSYS, probably not)
 * all data source libraries (curl, postgis, expat, ...) are a plus and Proj4 and GEOS of course
 * Useful: bash, gnuplot, and development tools: MinGW, MSYS, glade, doxygen
 * Not packaged yet, and no maintainer (presumably Ari Jolma would be the maintainer)
