I have added 6 ArcGIS Online layers to an ArcMap 10.3.1 project (.mxd). When I attempt to add additional online layers: "File --> Add Data --> Add Data from ArcGIS Online" ArcMap hangs for a second, releases, and no layer is added to the Table of Contents.

I have attempted clearing the Display Cache, as well as signing out of my AGOL Account. I am using an AGOL account affiliated with a University that does not have any credit limits. I have conducted a search and not been able to find any documentation from ESRI relating to maximum number of AGOL layers in an ArcMap project.

Has anyone else encountered this behavior, or detected a maximum number of AGOL layers?

  • I don't use Arc, but I have problems with QGIS when I try to add "online maps" that have different projections. Maybe not your issue, but worth checking. – Jon Dec 4 '18 at 18:12
  • all AGOL layers use EPSG 3867 WGS84 Web Mercator, projections is not an issue. it may be your desktop machine cant handle the high data peaks. – NULL.Dude Dec 6 '18 at 13:41
  • @Jon and NULL.Dude you are both on to something. My data frame was set to a local coordinate system, as the first layer I added to my project was a county boundary. AGOL layers are initially capable of projecting on the fly, but as the number of layers increases, I begin to experience a decrease in performance. USA Historical Topo Maps 1:250,000 scale would not draw. Changing the data frame to EPSG 3857 WGS_1984_Web_Mercator_Auxiliary_Sphere gets it to draw. – M. Graham Dec 7 '18 at 20:04
  • @NULL.Dude True, but at least in QGIS, your dataframe's CRS is set to be the same as the first layer you added, which may not be 3867. – Jon Dec 7 '18 at 23:01

Based on the comments, it appears that your problem is that your map dataframe is set to a different CRS than the online maps (which are all apparently EPSG 3867). Because of this, Arc is trying to reproject the Online Layers on the fly, which is a huge draw on system resources.

You can fix this by simply changing your dataframe to display the same CRS as the Online Layers.
