Geolocation Mapping Issue in ArcGIS Visual – Coordinates(Latitude,Longitude) Suddenly Inaccurate

Hi Anonymous ,

Thanks for posting in Microsoft Fabric Community.
I tested the behavior using the ArcGIS visual and observed the following:

Using only Latitude and Longitude without placing Site_Code in the Location well resulted in correct placement of the points in Virginia, United States. When only Site_Code was used without coordinates, some points were misplotted, such as Virginia appearing in Australia.

With all three fields :-Latitude, Longitude, and Site_Code used together, the map correctly showed the locations, but a message appeared stating that the data was outside the expected range for the WGS 1984 spatial reference. This indicates that while the coordinates were used, the Location field may still have triggered a geocoding validation warning.

The issue seems related to how ArcGIS interprets the Location field. Values like "Virginia, AUN1" can be ambiguous and may lead to incorrect results when used alone. One way to avoid this is by creating a new column with clearer geographic context, such as "Virginia, United States", and categorizing it as "Place" before using it in the Location well. 

Make sure the Latitude and Longitude columns are categorized as "Latitude" and "Longitude" respectively under the column data category in the model view. Using only these two fields for mapping while moving Site_Code to the Tooltip or Legend tends to give consistent and accurate results.

Also, please make sure that the Power BI Desktop is updated to the latest version to rule out any recent regression in the ArcGIS visual.

Hope this helps. Please reach out for further assistance.
