Locality Consistency

Consistency among locality fields in biocollections databases provides a first test for georeferencing error. ORNIS programmes will develop a workbench in which geographic references assigned via automated georeferencing will be compared with data fields for country, state, and county. If the geographic position indicated by the georeferenced coordinates does not fall within the appropriate polygon specified by the other fields (country, state, county), then logical inconsistency exists.
