Hello everyone!
I'm not exaclty sure where to post this - I'm working in ArcGIS Pro, but this may also be an Online question.
There may be a quick answer to this question - but I know at one point there was a resources (I think maybe on ArcGIS Online?) where you could report errors for basemaps.
I'm in the process of trying to create a prototype campus map (because we are discontinuing our other service and converting to an ArcGIS based map app) - and since the Open Street Map is in mature support, I'm having a difficulty time finding a basemap that is accurate to fit what we need. For example:
We have a little roundabout parking lot - this lines up with the satellite photography. Here is how it looks in the Open Street Map:

I've added some examples for how it looks in the current basemaps (see attachments) - I know how to update tile/basemap layers in the editor (which I've done before) but there isn't a way in the tile editor to reroute vectors. It's more like Mapbox than an actual editor program.
If anyone knows the link to send in errors for basemaps, feel free to send it my way (I know I've seen it before, but I can't find it now)
But I'm also curious what others have done when they find basemap errors in ArcGIS Pro. As a workaround, I may create some sort of shapefile-basemap layer I can put on top, but then I'll have to create all of the layers custom (ie roads) and I'm trying to make it easy for the people that will eventually take over this project.
Any advise is appreciated!
(feel free to move this post to a different board if I put it in the wrong place!)
