  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Latitude coordinates only provided on label: 2°45' N. Georeferenced to the approximate geographic center of Dadanawa in Upper Takutu-Upper Essequibo Region, Guyana; taking into account the added uncertainty of the word "near" stated in the locality description. Used Google Maps - Earth View to locate the village of Dadanawa. Used the Google Maps - What's Here Tool to find coordinates of the approximate geographic center of Dadanawa. Because the center of the nearest named place, Arakwai Outstation, is farther from the center of the named place than the linear extent of Dadanawa itself, followed Case A 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 the nearest named place, Arakwai Outstation, then halving this distance (3.77 km). Input coordinate source (locality description), coordinates, coordinate precision (.00001 degrees), datum (WGS84), extent of named place (3770.0 m), and measurement error (10 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to the Georeferencing Quick Reference Guide, Named Place: Near a Named Place). Latitude coordinates approximately match the coordinates provided on label.
