So here is another virtual machine with a lot of preconfigured open source GIS software. I have written about another similar project – GISVM – here. This virtual machine, in turn, is called Arramagong and is based on the XUbuntu operating system. It gives you access to a lot of open source geospatial software; furthermore, you do not have to install anything there since all the software has been already preinstalled and preconfigured for you. This machine has only free software, which makes it possible to freely distribute the virtual machine files after making your own modifications.
I found it worth checking out: many open source GIS products can be used together with ESRI software which allows you to take advantage of the open source software platform and benefit from powerful functionality of ESRI GIS products (check posts on binding ArcSDE and PostgreSQL as well as ArcGIS Server and OpenLayers).
