GPS Coordinates (Expanded) — Research Context

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Additional fields given for GPS coordinates such as PDOP.

This datatable is part of the KBS LTER Global Positioning System Data dataset.

The KBS LTER uses submeter accuracy GPS to record many locations such as plot corners, gas flux chamber, leaf litter trap locations, soil water samplers (lysimeter), etc.
