• Georeferencing Method

  Georeferencing Quick Reference Guide, Version 2012. Georeferenced to the approximate geographic center of the city of Porto Alegre (capital of the state of Rio Grande do Sul) in Mun. Porto Alegre, Rio Grande do Sul; taking into account the added uncertainty of the word "vicinity" stated in the locality description. Used Google Maps - Map and Earth View to locate the city of Porto Alegre. Used Google Maps - What's Here Tool to find coordinates of the approximate geographic center of Porto Alegre. Because the center of the nearest named place to the city is closer to the center of Porto Alegre than the linear extent of Porto Alegre itself, followed Case B of the Near a Named Place Method. Used Google Maps - Measure Distance Tool to find the linear extent by measuring from the selected coordinates to the farthest extent of the city (spatial boundaries provided by Google Maps). Input coordinates, coordinate source (locality description), datum (WGS84), coordinate precision (0.00001 degrees), extent of named place (22760 m), and measurement error (5 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (Named Place: Near a Named Place).
