  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. The locality description provides directions to an unnamed place from offsets of two named places; georeferenced this site as an offset from two distinct paths, in accordance with the Georeferencing Quick Reference Guide. First located Serra do Araçá in Amazonas, BR. To locate the mountain, referred to a topographic map of Serra do Araçá: DMA Aerospace Center. Serra do 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). Using Google Maps, located the geographic center of this mountain. Used Canadensys Lat/Long Crosshairs to find the coordinates. Used distance measurement tool (Google Maps) to find linear extent by measuring from the selected coordinates to the farthest extent of Serra Araçá. To find offset at 3 km. south of the geographic center of Serra do Araçá: input coordinates, linear extent (13486.3 m.), measurement error (.1 m.), offset direction (S), and offset distance (3000 m.) into the MaNIS Georeferencing Calculator to find the offset coordinates. Next, used Google Maps to locate Rio Jauari nearby, along the same approximate latitude as the coordinates. Used distance measurement tool to measure a straight line (horizontal) from the coordinates (at 3 km. south of geographic center of Serra Araçá) to Rio Jauari (at the tributary of the river closest to the west side of Serra Araçá, using clues from other locality descriptions), then used Canadensys Lat/Long Crosshairs to find the coordinates of Rio Jauari at this latitude. To find the coordinates for offset at 3 km. east of Rio Jauari at this latitude: input coordinates, linear extent (of Serra do Araçá, 13486.3 m.), measurement error (.1 m.), offset direction (E), 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 from two Distinct Paths).
