• Georeferencing Method

  Georeferencing Quick Reference Guide, Version 2012. Unable to find the precise location of "Igarapé Ipixuna;" instead, georeferenced to the land directly across Rio Negro from the tip of the city of Manaus in Mun. Iranduba, Amazonas. Used Google Maps - Earth View to locate the land directly across Rio Negro from the city of Manaus. Used the Google Maps - What's Here Tool to find the coordinates at this location. Because of the uncertainty of the extent of the region (difficult to define boundaries), used the Google Maps - Measure Distance Tool to find the approximate linear extent by measuring from the selected coordinates to the farthest extent of the land across from the city of Manaus along Rio Negro. Input coordinates, linear extent (22780.0 m), and measurement error (5 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to Georeferencing Reference Guide, Named Place: Undefined Area).
