Hi everyone,
I've already posted about this issue elsewhere, but I thought it might be helpful to post directly to the Living Atlas-specific forum.
Prior to the 3.6 update, I used the "Terrain - Hillshade" imagery layer from the Living Atlas on a daily basis. I used it in maps set to the NAD 1983 (2011) StatePlane [my state] coordinate system. I also used several other imagery layers, including "USGS Historical Topographic Maps," and I never had any problems getting these layers to display.
Now, after the update to 3.6, these layers no longer display in my maps... unless I change them to WGS 1984 Web Mercator. If I change to WGS84, they display without issue, but as soon as I switch back to NAD83, they don't display at all.
I tested this with two other co-workers: one co-worker who is using 3.6 and another who is still on 3.5.2. The co-worker on 3.5.2 could get the "Terrain - Hillshade" layer to display correctly in both WGS84 and NAD83, whereas the co-worker on 3.6 could only get the layer to display on WGS84.
I can't use WGS84 because I need to get accurate length and area measurements, and geometry calculations in WGS84 are wildly off from reality (which is well known by this point), so I have to use the NAD 1983 projection specific to my state. But I also would like to use the "Terrain - Hillshade" layer from the Living Atlas to avoid having to load in hundreds, and potentially thousands, of individual lidar tiles from my hard drive each and every time I make a new map.
If this problem has a solution, I'd be very happy to hear it. And if it's not on Esri's radar yet, I hope this helps bring it to their attention. Thanks.
Edit 02/27/2026:
Another forum member pointed out that changing a map to the NAD 1983 StatePlane [state] coordinate system will display the Living Atlas imagery layers, such as "Terrain - Hillshade" or "USGS Historical Topographic Maps." The problem seems to be isolated specifically to the NAD 1983 (2011) StatePlane [state] version. I haven't found any significant discrepancies in length or area measurements between the NAD 1983 StatePlane and NAD 1983 (2011) StatePlane, but I don't know that that will be true for everyone. I hope this helps as a temporary workaround until this issue is resolved.
Edit 07/15/2026:
I was just now able to update to 3.7.1, and it appears that the issue has been resolved. I didn't get a chance to install 3.7.0, but I'm assuming the change occurred then. The Living Atlas layers I use most (Terrain - Hillshade, USGS Historical Topographic Maps, etc.) are all displaying correctly in NAD 1983 (2011) StatePlane, like they were before the 3.6 update, at least as far as I can tell.
