Regional Models


Geoid model estimates (for continent or single state) are provided in gridded form and can be selected on a map or from an alphabetic list.

According to the specification of the geoid owner, the data sets are classified as

  • 'public' which can be directly downloaded,
  • 'on demand' for which a formal request can be sent to ISG to obtain the data,
  • 'private' which cannot be accessed.

Geoid models are provided in both their original format and in the unified ISG format (see specifications).
