Regional
Regional OBIS Nodes (RONs) are organizations that have committed to a continued support of OBIS within a geographic and/or national region using resources they have obtained. This includes serving data online and developing a data provider and end-user community. Some RONs provide tools and different language versions of the OBIS website.
Thematic
Thematic OBIS Nodes are organizations that contribute data to OBIS usually based on taxonomic group rather than geographic region.
