New Twist on "Open" Source?
There's alot of open sourcing in the mapping world, but here's a twist on traditional (boring ;) source code release models - The Carbon Project has included the source code for its powerful Gaia 3 viewer as part of the new CarbonTools PRO software development toolkit.
Under this model when folks acquire the software toolkit (CarbonTools) you get the source code for a nice application too (Gaia 3). Now, you can't turn around and give the source code away to the closest open source community - but you can take it and bake your own new mapping application (probably saving alot of time in the process).
I think this model will help bridge the gap between pure proprietary and open source software approaches - providing a good blend of both source code access and the professional support you get with commercial software.
Gaia 3 itself is pretty interesting stuff - allowing democratic access to Microsoft Virtual Earth, Yahoo! Maps, OGC WMS/WFS/WCS, Google Earth KML/KMZ, Geography Markup Language (GML), ESRI Shapefiles, Autodesk and MapInfo formats and more. Gaia 3 also supports geospatial-notes with digital pictures and custom map symbols that can be embedded in the content.
