 As WSL does not have an X server built in, you will need to install a 3rd party X server, such as https://sourceforge.net/projects/vcxsrv/

-* run Xlaunch from the start menu
-* Uncheck "Use Native openGL"
-* Add parameter ```-ac``` (WSL 2 only)
-* Open the Ubuntu WSL terminal

-        export DISPLAY=:0

-* or for (WSL 2)
-        ```
-        export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2}'):0

-
-The best map data source I've found so far is https://www.naturalearthdata.com. This has a lot of useful GIS data, but not airport runways, which you can get from the FAA Aeronautical Data Delivery Service (https://adds-faa.opendata.arcgis.com/)
-
-
-I've been using these files:
-
-* [Map geometry](https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_admin_1_states_provinces.zip) 
-* [Place names](https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_populated_places.zip) 
-* [Airport IATA codes](https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_airports.zip) 
-* [Airport runway geometry](https://opendata.arcgis.com/datasets/4d8fa46181aa470d809776c57a8ab1f6_0.zip)  
-
-The bash script getmap.sh will download (so long as the links don't break) and convert these. Alternatively, you can pass shapefiles and other arguments to mapconverter.py directly
-
-### MAPCONVERTER.PY RUNTIME OPTIONS
-
-| Argument						| Description |
-| ----------------------------- | ----------- |
-| --mapfile | shapefile for main map |
-| --mapnames | shapefile for map place names |
-| --airportfile | shapefile for airport runway outlines |
-| --airportnames | shapefile for airport IATA names |
-| --minpop | minimum population to show place names for (defaults to 100000) |
-| --tolerance" | map simplification tolerance (defaults to 0.001, which works well on a Raspberry Pi 4 - smaller values will produce more detail but slow down the map refresh rate) |

 If running as a front end only, with a separate dump1090 server, the best option is to use an Android phone, such as the Pixel 2, which significantly outperforms a Raspberry Pi 4.
