The  PHIVOLCS Geoportal Node is used to find and access geographic information (geospatial information) and associated geographic services (display, editing, analysis, etc.). Geoportals are important for effective use of geographic information systems (GIS) and a key element of Spatial Data Infrastructure (SDI).

Modern web-based geoportals include direct access to raw data in multiple formats, complete metadata, online visualization tools so users can create maps with data in the portal, automated provenance linkages across users, datasets and created maps, commenting mechanisms to discuss data quality and interpretation, and sharing or exporting created maps in various formats. Open portals allow user contribution of datasets as well.
