http://resource.geosciml.org/classifier/cgi/featureobservationmethod/outcrop_observation	outcrop observation	"Data collected in field through direct observation of a single outcrop. Observer defines scope of 'single outcrop'--may be one point location, or averaged over an extended but connected) area, e.g. a single polygon on a map. Direct observation may include observation using a remote camera (e.g. downhole viewer, submarine camera)"	this vocabulary
