I'm planning to build a cabin, and I'd like to combine all the GIS data available from my home country with my own measurements for placing and the cabin layout. That is, I need a tool which can:
- save data in layers,
- import third-party GIS data for elevation, infrastructure, etc., and
- import a PDF, SVG or other vector graphics format to get the cabin layout.
Is there any software useful for this available for Linux (at a pinch Windows XP), preferably for free?
