[GeoNode-users] Newbie / Evaluating GeoNode

Tue Oct 20 06:25:54 PDT 2020

Hi Mike,

Just yo follow Up on your other questions, you can use any of the base maps
you mentioned, OSM is included by default, but you can add your token for
Bing Maps, Mapbox, etc., to your settings file and they will be display in
all your maps and you will be able to choose wich base map you want to use.

Kind regards
