I am looking for some (preferably free) GIS software that will enable me to export multi-layered world maps (made up of shape-files and kml files and so on) as hi resolution (21,000 pixels wide), single layered tiff, jpeg or other raster format files, so that i can then edit them in photoshop.

I am an artist, and new to GIS. I have recently started running the free Mapwindow program on my computer. This has enabled me to start constructing some of the world maps that I'm looking for, though I cant seem to find a way of exporting them as images from that program.

Did you try Qgis? I think wil cover you. You wil find a lot of help on Internet. It is very easy to manipulate the data. If you want to change their style or icons it is very easy. And of course Tiff export is a standard. Is open source and cross platform, that mean you can install it in any Opereting System.

Download: From here [Standalone Installer (recommended for new users)]
