  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Georeferenced to approximate geographic center of Areia Branca, between the cities of Porto São José and Marilena, in Paraná, Brazil. Used Google Maps - Satellite and Map Views to locate the city of Areia Branca. Used the Google Maps - What's Here Tool to find the coordinates of the approximate geographic center of the region of Areia Branca (-22.729501, -53.122148). Because Areia Branca does not have defined spatial boundaries, used the Google Maps – Measure Distance Tool to find the linear extent by measuring from the selected coordinates to the approximate geographic center of the nearest named place, Porto São José (-22.718425, -53.174506), then halving this distance. Input: coordinates (-22.729501, -53.122148), coordinate precision (0.00001 degrees), datum (WSG48), linear extent (5.5 km), and measurement error (0.01 km) into the MaNIS Georeferencing Calculator to find the uncertainty radius (5512 m). According to Georeferencing Quick Reference Guide: Named Place, Undefined Area.
