I would like add my experience to this, a month ago I pick metabase as the default data visualization tool for the company I work for, we have to do pin map for some data to visualize but we are behind firewall, internet access is not allowed and is not on the options. we come up with offline map, we downloaded osm mbtiles files and we use tile server to serve the tiles. like others mentioned the whole process was really fun and rewarding. I have touched many stacks and used many software to do the work. Motivated by that I am also implementing a complete offline map of large selected area with satellite images and 3d view. If anyone interested happy to help.
