• Georeferencing Method

  Georeferencing Quick Reference Guide, Version 2012. Unable to find the precise location of "Lago Preto;" instead georeferenced to 2 km. north of the geographic center of the city of Lábrea for the approximate location of the lake. Using Google Maps - Satellite View, located the city of Lábrea which sits along Rio Purus in município Lábrea, Amazonas. Used Canadensys Lat/Long Crosshairs to find the coordinates of the geographic center of the city. Used Distance Measurement Tool (Google Maps) to find the linear extent by measuring from the selected coordinates to the farthest extent of município Lábrea. To find 2 km. north offset: input coordinates, linear extent (380836.0 m.), measurement error (1 m.), offset direction (N), offset distance (2000 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).
