It has over 350 rock-solid vector and raster manipulation tools. Not awfully useful in cartographic design, GRASS GIS excels primarily as a free GIS software option for analysis, image processing, digital terrain manipulation, and statistics.
The cartographic mapping software tools are primitive compared to QGIS. But overall Whitebox GAT is solid with over 410 tools to clip, convert, analyze, manage, buffer and extract geospatial information. I find it amazing this free GIS software almost goes unheard of in the GIS industry. Get more useful knowledge from the Whitebox GAT Open Source Blog.
I am a geologist currently use Mapinfo 8.5, which is barely an improvement on Mapinfo 4.5, and now Mapinfo is somewhere around MI15 or so and I have no intention of buying yet more upgrades for a relatively clunky cartographic/GIS system. I am thinking of migrating to QGIS. A key issue in geology is the third dimension and having symbols (e.g. dip and strike of strata) so as to image 3D on a 2D map. Discover was written to accompany Mapinfo a good time ago to do this but again one pays through the nose to buy it and its upgrades. Is there any freeware add-on to QGIS that will do what Discover does?
The historical map collection has over 120,000 maps and related images online. The collection includes rare 16th through 21st century maps of North America, South America, Europe, Asia, Africa, Australia, Antarctica, the Pacific, the Arctic, and the World. The online map collection is a searchable database that allows you to make your own journeys into spatial representations of the past. Here you can see the history of cartography through primary sources from 1500 into the 21st century. 2b1af7f3a8
