Georeferencing Method: Georeferencing Quick Reference Guide, Version 2012 (Referred to wikimapia.org for locality information for Serra de Jacuba (http://wikimapia.org/21870181/Jacuba-Hill, accessed: 7/27/2015). Georeferenced to the approximate geogrpahic center of Serra de Jacuba, situated west of the city of Filadélfia, in Tocantins, Brazil. Used the reference material, locality clues, and Google Maps - Terrain Views to locate Serra de Jacuba. Used the Google Maps - What's Here Tool to find the coordinates of the apporximate geogrpahic center of the hill. Used the Google Maps - Measure Distance Tool to find teh coordinates of the farthest extnet of the expanse of the hill. Input coordiantes, coordinate precision (.00001 degrees), datum (WGS84), linear extent (891.95 m), and measurement error (5 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to the Goereferencing Quick Referecence Guide, Named Place: Defined Area).)
