  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Georeferenced to 3 km. south of the geographic center of Serra Araçá. Referred to a topographic map of Serra Araçá: DMA Aerospace Center. Serra Araçá, Brazil [map]. 1:250,000. St. Louis, MO.: DMA Aerospace Center, 1994 (provided by the University of Texas website, http://www.lib.utexas.edu/maps/jog/latin_america/txu-oclc-224388740-na20-14.jpg) and an aerial photograph of Serra Araçá provided by "Skyscraper City" website (http://i1092.photobucket.com/albums/i406/fredsonsantiago2011/Barcelos%20-serra%20do%20Araca%20e%20rios%20da%20regiao/Barcelos4-SerradoArac9.jpg) to locate area of Serra Araçá. Using the reference material and Google Maps, located Serra Araçá in Barcelos, AM. Used distance measurement tool (Google Maps) to measure the total extent of Serra Araçá; halved this distance to approximate the location of the geographic center of the mountain. Used Canadensys Lat/Long Crosshairs to find the coordinates of the geographic center. Used distance measurement tool (Google Maps) again to find linear extent by measuring from the selected coordinates to the farthest extent of Serra do Araçá. Input coordinates, linear extent (13486.3 m.), measurement error (.1 m.), offset direction (S), offset distance (3000 m.), and distance precision (100 m.) into the MaNIS Georeferencing Calculator to find the offset coordinates and uncertainty radius (according to Georeferencing Quick Reference Guide, Offset: Offset at a heading).
