What Is Geomatching

Tables often reference countries, states, or other regions without including the geometry themselves. Historically, you’d have to join this data with other datasets to work with it on a map. Felt does this automatically with Geomatching.


Available Geomatching Regions

Data will be checked for the geographic regions listed below and converted to polygon geometries when possible. Optionally, hints present in the column name can be used to choose among valid matches, such as “zip” used to name a column of U.S. ZIP codes.
