Geospatial enabled PDF export may result in incorrect coordinates and measurements in Adobe Acrobat

Description

Sometimes when users export a geospatially enabled PDF from ArcGIS Pro, they see incorrect coordinates and measurements in Adobe Acrobat.

Cause

This is caused by a setting in Adobe Acrobat called “Always display latitude and longitude as WGS 1984”. This is enabled by default in Acrobat and forces the PDF into WGS 1984, which can cause incorrect coordinates or measurements if the PDF was explored with a different datum.

Solution or Workaround

To correct this, uncheck the Always display latitude and longitude as WGS 1984 option as follows:

1. Navigate to the 'burger' menu at the top left-hand corner of Adobe Acrobat,
2. Select Preferences, and open the Measuring (Geo) page, as shown in the image below.
3. Uncheck Always display latitude and longitude as WGS 1984, and click OK.

After unchecking this option, the PDF will be displayed in its correct datum, chosen upon export.
