@SCYou and I have been linking location and GADM database to study air-pollution using GIS.
The location information of patients are contained in the person table. However, the change of the location information can not be updated because of the structure of the table.
I wonder if the THEMIS-Focus Group 4 and the GIS Working Group are also aware of this concern and are going to continue working on to fix it.
I think inputting the location information in the observation table would be an alternative
example (arbitrary value) :
observation_concept_id = 4077707(Location)
