Is it possible to add Geoserver to Qgroundcontrol, replacing Google, Yahoo, Microsoft and other mapping services ? Opengts allows this, and we have it working with maps, GeoTiffs, we created from scratch. We do this for a couple of reasons; 1. we need more detail than what is offered by ordinary mapping services 2. there are no fees to be paid should you be using one of these service for a money making venture.
Land vehicles may be in more need of detailed maps than aircraft.
Nice idea, although I think a better approach would be to add a WMS client which could access a Geoserver or any other wms map server.
