If you would like to know the source of a variable, you can review the metadata information by hovering over the Action menu on each variable.
When you mouse over a variable, the Action Menu will appear. Use this menu to view metadata, add the variable to your favorites list, or use the variable (add it to the active map or report).
Viewing a variable's metadata will provide you with the name, path, definition, and data source.
If the metadata doesn't answer your question, and you still need more information about a location, feel free to contact our support team at: firstname.lastname@example.org
