  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Referred to wikimapia.org for additional locality information for Pedra da Gávea (http://wikimapia.org/632350/Gávea-Rock-Barra-Rock, accessed: 12/9/2015). Elevation contour lines in this region do not appear precise; not able to distinguish between elevations between 700 m and the peak (approx. 844 m). Georeferenced to an elevation of approximately 700 m nearest to the approximate geographic center of Pedra da Gávea in the city of Rio de Janeiro. Used the reference material and Google Maps – Earth and Terrain Views to locate Pedra da Gávea. Used the Google Maps – What's Here Tool to find the coordinates of elevation 700 m nearest to the approximate geographic center of the mountain (used Earth View to approximate this; Terrain View does not provide exact elevation contour lines in this vicinity). Used the Google Maps – Measure Distance Tool to find the linear extent by measuring from the selected coordinates to the farthest extent of elevation 700 m contour line (to: -22.998867, -43.282634). Input coordinates, coordinate precision (.00001 degrees), coordinate source (locality description), datum (WGS84), linear extent (136.04 m), and measurement error (5 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to the Georeferencing Quick Reference Guide, Named Place: Bounded Area).
