I need to add a very specific coordinate system to my map that is county specific. I've asked the county and they said it should be available, but I cannot seem to find it. What are the steps to look for coordinate systems?
Thanks!
Hi Michelle,
It looks like you are asking about ArcGIS Online. Are you asking about ArcGIS Pro? In Pro, you can search for coordinate systems by looking at the Map Properties. Your specific county may have a projection file (.prj format) that might be easiest to load.
Take a look at this article on how to specify a coordinate system in Pro (if that is what you are using):
https://pro.arcgis.com/en/pro-app/latest/help/mapping/properties/specify-a-coordinate-system.htm#GUID-010AE52D-19C8-4D40-9585-78E5C55DEBF8
ArcGIS Online defaults to just the generic Web Mercator. To work with coordinate systems in ArcGIS Online, take a look here:
