Beautiful cartography using OpenJUMP

An OpenJUMP user just posted some really nice cartographic maps made using a combination of OpenJUMP, Inkscape, GRASS, and GIMP.

He gives OJ the following glowing endorsement:

I find Open JUMP to be the most vector-friendly open source GIS software. The preparation of the datasets (rivers, lakes, sea, roads, borders) was really [a] piece of cake...

It's great to see the small but dedicated OpenJUMP community steadily adding new features and improving the software quality.  10 years after it was launched, OpenJUMP continues to be the "Little Open-Source GIS that Can".
