Georeferencing Method: Georeferencing Quick Reference Guide, Version 2012 (Referred to geotagged photos on Panoramio.com (http://www.panoramio.com/user/8025076/tags/Pedra%20Elefantina, accessed 7/29/2015) for additional locality information for Pedra Elefantina. Georeferenced to the approximate geographic center of Pedra Elefantina along the borders of Rio de Janeiro and Minas Gerais in Brazil. Used the reference material and Google Maps - Terrain and Earth Views to locate Pedra Elefantina. Used the Google Maps - What's Here Tool to find coordinates of the approximate geographic center of the rock formation. Used the Google Maps - Measure Distance Tool to find the linear extent by measuring from selected coordinates to the farthest extent of the rock (slightly overextending this measurement to encompass the entire area which may be considered part of the rock, to: -20.986846, -42.154098). Input coordinate source (locality description), datum (WGS84), coordinate precision (0.00001 degrees), extent of named place (921.90 m), and measurement error (10 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to the Georeferencing Quick Reference Guide, Named Place: Bounded Area).)
Coordinate Uncertainty(m): 933.469
Geodetic Datum: WGS84
Coordinates: (-20.9787, -42.1529)
