offline map tiles tar1090 - wiedehopf/adsb-wiki GitHub Wiki
This assumes you already have tar1090 running on a linux and not in a container (like this: https://github.com/wiedehopf/adsb-wiki/wiki/Raspbian-Lite:-ADS-B-receiver)
1. Download the tiles (700 MB download, disk space required around 2 GB)
curl https://raw.githubusercontent.com/wiedehopf/adsb-scripts/master/osm_tiles_offline.sh | sudo bash
2. optional: Download extra detailed tiles (1.3 GB download, disk space required around 4 GB)
This doesn't work without step one.
curl https://raw.githubusercontent.com/wiedehopf/adsb-scripts/master/osm_tiles_offline_10.sh | sudo bash
Finish tar1090 integration
Even with already installed tar1090, run the install / update script for tar1090, it will autodetect the tiles installed above: https://github.com/wiedehopf/tar1090#installation
You should now have an offline map layer available using the map layer selection menu (top right of the map).
