Class: Georeference::VerbatimData

Inherits:
Georeference show all
Defined in:
app/models/georeference/verbatim_data.rb

Overview

The Georeference that is derived exclusively from verbatim_latitude/longitude and fields in a CollectingEvent.

While it might be concievable that verbatim data are WKT shapes not points, we assume they are for now.

!! TODO: presently does not include verbatim_geolocation_uncertainty translation into radius !! See github.com/SpeciesFileGroup/taxonworks/issues/1770
