  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Georeferenced to the geographic center of the mouth of Rio Içana, a tributary of Rio Negro, in Amazonas, Brazil. Using Google Maps - Satellite View, located the mouth of Rio Içana. Used Canadensys Lat/Long Crosshairs to find the coordinates of the approximate geographic center of the mouth (confluence of Rio Içana and Rio Negro). Used the Distance Measurement Tool (Google Maps) to find the linear extent by measuring from the selected coordinates to the farthest extent of the confluence of the rivers. Input coordinates, linear extent (1528.4 m), and measurement error (.1 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to Georeferencing Quick Reference Guide, Named Place: Mouth or headwaters of a river, confluence of waterways, trailhead).
