    wms2go
    The project wms2GO is designed to build a local executable WebGIS application out of pre-defined or manual selected WMS (OGC WebMapServices) of free map extract. Thus it is possible to use this application on a mobile device (e.g. a laptop) without any network access. Manuals for Installation and Setup have been added to the SVN. You can find them here: http://wms2go.svn.sourceforge.net/viewvc/wms2go/wms2go-help-1.0/ At the moment, they are only available in german, but this may change in the future. A demo client is published under: http://wms2go.dlz-it.de/
