Thanks! I used QGIS (a free, open source, geographic information system) to make & render these files. All except the .qmd file could also be opened in ArcGIS or or another GIS package. And the .csv file can also be opened and edited in Excel or Google Sheets, as it's just a data table.

There's an old-ish tutorial for using QGIS for RPGs on my blog.
