Stealing John Nelson’s Imhof-Inspired Style

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 simple: satellite imagery, under a regular hillshade, under a multi-directional hillshade, under a “mist” linked to elevation. Here is how I made my own version in QGIS. You need a base image to use. I found that using the Quick Map Services plugin you can get some good imagery using the EOX::Maps – Sentinel-2 cloudless layer. You might have other imagery that you prefer. Then, you need a digital elevation map for your area. If you have one, great. If not, then the SRTM data is probably your best bet, since that has 30m accuracy for most of the globe. You will need to export this into a projected coordinate system, like the UTM zone best suited for your area of interest, or the hillshading will go a bit squiffy. Apparently the hillshade uses the units it is projected in, so working with a DEM […]


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 a Download Source: Select Install from Internet Select Root Installation Directory: I stick with All Users. Select local Package: The default works fine. Select you internet connection: Whatever you have to, mine is a Direct Connection. Choose a download site: http://download.osgeo.org works fine, but if you have a mirror that you need, add it here. Select Packages: These are expandable. So find Desktop and expand it. If it is not installed yet, then you will look for qgis-dev in the Package column. Click on the New column for that row and change Skip to the version that you wish to install ( as I write this). [Edit: you should also install qgis-dev-pdb, which will improve the debugging of any issues that do crop up.] If you are updating, it should show a different number for Current and New. Resolve Dependencies: You should probably install the […]
