Coordinate Uncertainty (m)
Georeferencing Quick Reference Guide, Version 2012. Georeferenced to the approximate geographic center of the city of Santarém, Pará; accounting for the added uncertainty of the word "vicinibus" (vicinity) stated in the locality description. Used Google Maps – Earth and Map Views to locate the city of Santarém. Used the Google Maps – What's Here Tool to find the coordinates of the approximate geographic center of the city of Santarém. Because the center of the nearest named place of similar locality type (smaller city, considering that true nearest named place is a village and may be under jurisdiction of Santarém), Alter do Chão, is farther from the city of Santarém than the linear extent of Santarém itself, followed Case B of the Near a Named Place method of the Georeferencing Quick Reference Guide. Used the Google Maps – Measure Distance Tool to approximate the linear extent by measuring from the selected coordinates to the approximate geographic center of Alter do Chão (at: -2.510211, -54.948816), then halving this distance. Input coordinates, coordinate source (locality description), coordinate precision (.00001 degrees), datum (WGS84), linear extent (12050.0 m), and measurement error (5 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to the Georeferencing Quick Reference Guide, Named Place: Near a Named Place).
