Does this mean that without the Google Maps integration Neatline won’t work at all?
Are there any open source options instead of using Google Maps with Neatline? I read something about a Leaflet integration on the Twitters but I haven’t been able to find any installation/setup instructions.
Neatline for Omeka Classic comes with Open Street Maps and Stamen maps, so unless you need Google Maps, you can just use the open source maps, avoiding Google.
Neatline for Omeka S will integrate Leaflet, but it will not work for Neatline 2.x.
