Within the context of USGIN, the National Geothermal Data System (NGDS), and the AASG Geothermal Data project, content models are Excel workbooks which contain template spreadsheets.

Content models provide NGDS schemas that are designed to facilitate interoperability. Any data submitted for the AASG Geothermal Data project by Arizona Geological Survey subrecipients must be structured by an NGDS schema provided by an NGDS content model.
