• Georeferencing Method

  Georeferencing Quick Reference Guide, Version 2012. There are multiple localities that could be "S. Gonçalo" in Paraíba, Brazil. Referred to another collection from the same collector (Luetzelburg) in the same time period of this collection (April 1936) to determine that this collection locality is the city of São Gonçalo, nearby Mun. Marizópolis. Georeferenced to the approximate geographic center of the city of São Gonçalo in Mun. Sousa, Paraíba. Used Google Maps – Earth and Map Views to locate the city of São Gonçalo. Used the Google Maps – What's Here Tool to find the coordinates of the approximate geographic center of the city. Used the Google Maps – Measure Distance Tool to approximate the linear extent by measuring from the selected coordinates to the nearest named city, Marizópolis, then halving this distance. Input coordinates, coordinate source (locality description), coordinate precision (.00001 degrees), datum (WGS84), linear extent (1880.0 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: Undefined area).
