Add geometry values to vector layer in GRASS GIS

In my previous post I explained how to add geometry values to the attribute table of a vector map in QGIS. You can do the same in GRASS GIS. It is slightly more complicated (don’t worry, it is still easy enough), but also more powerful. Below I will briefly explain how to use this tool using the GUI or command line.

QGIS symbology set

If you are planning to make (nice looking) maps, you might want to check out QGIS. It amongst others offers a lot of options and flexibility to make your own symbols (see e.g., this blog for a nice example).

But not everybody will want to develop their own sets of symbols, so having a nice set of symbols to choose from would definitely be an asset.

And this is exactly what Mithantrope’ s Thoughts is providing. Check out his blog post QGIS symbology set, which provides a whole set of great looking QGIS symbology. And if you like it, you can download it and start using it (instructions are included).

Creating a map using the command line

Although I like to carry out GIS analyses using the command line interface (CLI), creating maps is something I still tend to do using the graphical interface (GUI). And most of the time that makes perfect sense to me, creating something visual (the map), using visual tools (GRASS GUI gis.m or QGIS).

But things change when e.g., you have to create many maps of the same area changing one variable only, Continue reading “Creating a map using the command line”
