The service provides geology data and mapping through a set of web services built on the MapService platform of the Open Geospatial Consortium (OGC). That architecture exposes datasets to a number of OGC-compliant desktop clients as well as the service's own REST and SOAP APIs. Data include datasets for seismograph recordings and geological sample profiles from the System for Earth Sample Registration (SESAR).
API methods support queries against XML records of seismology datasets recording earthquakes and other geological events. Methods also support retrieval of analytical data for samples of rock, minerals, and other geological materials by universal identifiers created at the time the samples are collected. Methods for managing samples also allow uploading of new records documenting sample collections for users who have registered accounts with the service.
