Hello Stan,
Accidentially I pressed the solved button.
I am not an expert on Geo data and still with JMP17.2 in case there are changes in JMP18
I am just using it from time to time for visualisation of election data.
While the federal goverment is providing the election districts in decimal degree it is easy to get the maps in JMP.
The states are using different geo data format as shown e.g. for Hessen and Bavaria in the attached picture.
May be the *.prj Information can be used for convertion into decimal degree which is used by JMP.
I attached the three different map data.
Best regards
Mirko
