  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Referred to Geonames.org (http://www.geonames.org/maps/google_-25.45_-51.867.html, accessed: 6/23/2015), and wikimapia.org (http://wikimapia.org/#lang=en&lat=-25.451606&lon=-51.926751&z=15&m=b&search=-25.45%2C%20-51.86667, accessed: 6/23/2015) for locality information for Lagoa Sêca. Georeferenced to the approximate geographic center of the village of Lagoa Sêca, Paraná, Brazil. Used the reference material and Google Maps – Earth View to locate the village of Lagoa Sêca on highway BR-277 (to Ponta Grossa). Used the Google Maps - What's Here Tool to find the coordinates of the approximate geographic center of the village (-25.447968, -51.925602). Because Lagoa Sêca does not have defined spatial boundaries on Google Maps, used the Google Maps – Measure Distance Tool to approximate the linear extent of the city by measuring from the selected center coordinates to the approximate geographic center of the nearest named place, Campo Real (-25.450803, -51.799474), then halving this distance. Input: coordinates (-25.447968, -51.925602), coordinate precision (0.00001 degrees), datum (WSG48), linear extent (6.3 km), and measurement error (0.01 km) into the MaNIS Georeferencing Calculator to find the uncertainty radius (6311 m). According to the Georeferencing Quick Reference Guide: Named Place, Unbounded Area.
