• Georeferencing Method

  Georeferencing Quick Reference Guide, Version 2012. Unable to find the precise location since locality described in time (hours), not distance; georeferenced to the approximate geographic center of Rio Anajás on Ilha de Marajó, Pará. Using Google Maps - Satellite View and Terrain View, located Rio Anajás. Used Distance Measurement Tool (Google Maps) to measure a straight line starting at the mouth of the river (where it branches off from Rio Jacaré) to the approximate end of the river (where it divides into two unnamed rivers), then halved this distance to approximate the midpoint of Rio Anajás. Used Canadensys Lat/Long Crosshairs to find the coordinates, on the adjacent northern shore of the river. Input coordinates, linear extent (distance from the selected coordinates to the farthest extent of Rio Anajás, 75518.9 m.), and measurement error (.1 m.) into the MaNIS Georeferencing Calculator to find the uncertainty radius.
