The Geothermal Data Exchange (GDEx) handles data generated by geothermal projects and other geothermal-related data not handled by other data sites. It serves as a portal for finding data on a wide array of geothermal energy issues. The basic components of the GDEx are the "digital library", "discrete database" and the mechanisms to find data of interest ("search and discovery"). Through web applications, GDEx provides a core solution for data acquisition, management, maintenance, and access. The goal of GDEx is to become a convenient and powerful resource to help researchers, industry, and others meet their routine needs for data access and management.
