Based on Criss’ suggestion, this is possible via…
tell application id "DNtp" to set latitude of (contents of (current database)) to ""
This would remove the geolocation data displayed for the files in a database since it can’t be resolved without both the latitude and longitude.
For a cleaner approach, you can use…
tell application id "DNtp"
tell current database
with timeout of 3600 seconds -- just as a safety measure, but likely unnecessary
set latitude of contents to ""
set longitude of contents to ""
end timeout
return geolocation of contents
--> {}
end tell
end tell
