Hello, is there an issue with data being projected and then published to AGOL but not retaining the projection it was published with? I noticed a few instances of this with our data, and based on a previous Esri Community post (https://community.esri.com/t5/arcgis-online-questions/coordinate-system-issue-with-layers-hosted-on/td-p/1299577) it makes me wonder if it's when the data is projected but the map itself at time of publishing is not displayed using the same projected coordinate system.
If so, is this intended behavior or a bug? It seems like the projection of the data should not be affected by the projection of the map.
Thank you!!
Thank you! I genuinely had no idea this was the case. It's a hard issue to catch too sometimes because the default projection for the map itself depends on whichever layer is added to the map first.
Here is blog & technical article that talks about this:https://www.esri.com/arcgis-blog/products/arcgis-online/data-management/how-publishing-paths-determine-coordinate-systems-in-hosted-feature-layershttps://support.esri.com/en-us/knowledge-base/problem-the-projected-coordinate-system-of-a-feature-la-000033827Hope this helps!
There was a good ArcGIS Blog post about this recently: How Publishing Paths Determine Coordinate Systems in Hosted Feature Layers
In short yes, if you "publish as web layer" or "share as web layer" from ArcGIS Pro, the layers will have the projection of the map they're published from. If you published them some other way, check the article.
