Our organization is looking to set our default ArcGIS Pro basemap to be different than our default ArcGIS Online basemap.
Our current basemap in in WGS 1984 which is great for the web, but not so great when it comes to measuring or analyzing our UTM15N data. Since ArcGIS Pro's map frames take the projection/coordinate system of the first layer added to the map (basemap) the rest of the data added later is re-projected on the fly. Since this basemap is a default, our users (wide variety of departments) don't always think of this, and it can lead to incorrect measurements/ accuracy issues.
We currently have a basemap in UTM 15N, but don't want to make this the ArcGIS Online default. We're looking to set the ArcGIS Pro default to be independent of the ArcGIS Online default.
Please consider this, we would be happy to talk about this more over a call as well.
