Interpretation in TERN Plot Ontology
Encoding each row in RDF requires:
A
plot:Locationto capture most of the column values with its datatype properties.A
geosparql:hasGeometryto capture the latitude and longitude coordinates.A
plot:locationMethodto capture the method used to determine the location.A plot:Location is location of a plot:Site (plot-x:isLocationOf)
