Welcome to the Earth Science Ontology Portal (ESIP Portal) for the Federation of Earth Science Information Partners (ESIP). The ESIP Portal is a Web-based application for accessing and sharing earth science ontologies. You can create ontology-based annotations for your own text , link your own project that uses ontologies to the description of those ontologies , find and create relations between terms in different ontologies, and review and comment on ontologies and their components as you browse them. Please Sign in to submit a new ontology or ontology-based project, provide comments on ontologies, or add ontology mappings.
