High-level geographic data thematic classification to assist in the grouping and search of available geographic data sets. Can be used to group keywords as well. Listed examples are not exhaustive.
Note: It is understood there are overlaps between general categories and the user is encouraged to select the one most appropriate.

Upcoming API change — enumeration
According ISO 19115, TopicCategory shall be an enumeration, not a code list. This class may be changed to a Java enum in GeoAPI 4.0. See GEO-199 for more information.

Since:

2.0
