Over a year ago, I posted about GISVM, a Linux GIS workstation in a virtual package that could be run in free VM software like VMWare Player or Virtual Box. You can now try out a more recent release of this package (christened Arramagong, and distributed at the 2009 FOSS4G conference in Australia) in a Java-based virtual machine viewer at the click2try website. You need to register (for free) to save data and settings, but you can try it out without registration. You’ll definitely need a broadband connection to run it, and there’s a connection test to make sure your network link is up to it. Once running, display refresh speed is adequate enough to load up apps and try them out. Wouldn’t want to run the apps full-time on this service, but that’s certainly not the intention for this package – it’s just to show off what’s available in the distribution. If you like it, you can always download the 1 GB+ full distribution and a free virtual machine environment, and run it at acceptable speed on your own computer.
In addition to the apps you see listed above, it also has qGIS, uDig, RGeo, openJump, and MapTiler
