I have a building footprint layer and would like to see this when adding a geopoint location. Does someone know of a way to include external feature classes, shapefiles or AGOL published feature layers that are viewable on the geopoint map?
Hi. At the moment what you would like to do is not possible. You can only change the basemap (to your own or an esri basemap), but you cannot add additional layers on top of the basemap.
You could burn it into a basemap by creating your own tpk. We use this for roads over imagery where the roads are white.
