Recently I needed to generate a number of maps of the same place, but with different raster data for map. Given that I had way too many for me to want to manually manage each raster layer, I asked for a different approach on the Spatial Community Slack, and this is what was suggested: Create […]

Recently, because I like cartography stuff, I have been seeing a blogpost by John Nelson at ESRI about a very pretty style that he developed. It is inspired by the style of Eduard Imhof. John’s style is developed for ArcGIS Pro. I, on the other hand, use QGIS. At its heart, the style is pretty […]

QGIS Nightly Install – Windows
For my own reference, as much as anything else, how to install the latest nightly for QGIS on Windows using the OSGeo4W installer. Download the OSGeo4W for your version of Windowsfrom the QGIS Website. For me I ended up getting and running osgeo4w-setup-x86_64.exe. From here, the following is a step-by-step guide: Select Advanced Install. Choose […]
Something that I have idly been pondering for a few weeks now has to do with the renaming of streets. Durban, the most populous city in KwaZulu-Natal has renamed a lot of them in the last decade or so. Since I mentioned it obliquely on Twitter (1, 2) earlier, I thought I would write it […]
To finish off the field school, everyone gave a presentation. The geophysics groups gave one on a particular scientific question, while the geochem people talked about what they had been up to. These were generally pretty cool, especially the geochem. This was mostly because I had no real idea what they had been up to, […]
This morning we had a very interesting talk from two consulting geophysicists, who formed a company named MeerCAT. (I can not find a website for some reason, but will try and add it if I come across it. The closest I have is a (LinkedIn profile)[https://za.linkedin.com/pub/lindsay-linzer-nee-andersen/6/b60/b79].) Something slightly unusual about this consulting company is that […]
Day 16 – GPR, or mowing the pavement. This morning was an interesting overview of the uses and limitations of ground-penetrating radar (GPR), which looks like a really useful tool. This was given by (Red Dog Scientific Services)[http://reddoggeo.com/]. I can think of a couple times it would have been useful for the geotech work I […]
Day 14 – Pilanesberg Today was an opportunity for the tourists to see somewhere new, including some animals, with a visit to the Pilanesberg Game Reserve. Since I have done a fair amount of game-viewing, I decided to give it a miss. Instead I met some old friends, and had a generally lovely day (including […]
Part two of the field component of the field school. Again, this is a collection of pre-written posts. AfricaArray Field School – Day 10 We had a bit of a rest day today, in order to collect samples to determine their physical properties. For some reason, each group needed ten samples of each lithology, of […]
So connectivity for me was particularly poor out in the Dome, but I did write what happened, so here is the day-by-day, as I typed it up in the field. This is a long entry, so I will probably break it up into two. I will not put any photos in, because most of the […]
