Description

This vocabulary provides a set of classes to support capturing of plot- and site-based ecological survey data. It is primary related to vegetation surveys, following the methpdologies outlined in the Australian Soil and Land Survey Field Handbook.

TERN ontology is technically an extension to the W3C SSN/SOSA vocabulary, and also uses elements from the SSN Extensions ontology.
