Use QGIS to model potential overland routes between sites in a gazetteer and export a map (as a .jpg or .pdf) showing your results. Read these instructions to get ready for the exercise, then follow the specific steps outlined in the video. Specifically, we will be using the GRASS 7 r.walk and r.drain functions in QGIS 3.4 to calculate the least-cost paths between select points. We will then experiment with different visualization options for making a map.
Software
Download and install QGIS version 3.4 (long-term release). Next, install the QuickMapServices plugin (see video tutorial for instructions on installing the plugin).
Data
You will need three datasets for this exercise: (1) a point shapefile containing at least three places, (2) an elevation raster that covers the same extent as your shapefile, and (3) a hillshade computed from the elevation raster.
- Option 1: Download the example dataset, which contains a list of places that Colonel William Leake visited in the southern Peloponnese in 1805. If you need an application to unzip a compressed file, you can download the free 7-zip tool.
- Option 2: For students who have taken the previous seminar on "Digital Gazetteers", you are welcome to use the data produced from the related exercise or project. You will need to export your annotated places as a GeoJSON file, then import the file into QGIS and save it as a shapefile. You will also need to download an elevation raster for the area where you will calculate overland travel, then compute the hillshade from this dataset. One free source is 30-meter resolution SRTM data, which you can search for using the USGS Earth Explorer Tool.
