 Directus supports various databases, though each vendor has their own simple data types. To standardize these differences, Directus has a single set of types that are mapped to the vendor-specific ones.

 Fields that do not map directly to an actual database column are called "alias" fields, and include presentational fields and certain relational fields.
 
+Geospatial fields are used to store data in [GeoJSON](https://geojson.org/) format. These types are only supported if your database supports spatial extensions.

 ## Creating Fields
 
 When creating a new field, you must first select an [interface](/data-modeling/interfaces) and provide some basic configuration. Basic configuration will depend on the interface selected, but all fields have some common characteristics.
