  • Georeferencing Method

    Georeferencing Quick Reference Guide, Version 2012. Georeferenced to the area east of the village of the village of Rockstone in Upper Demerara-Berbice, Guyana. Used the Google Maps - Map and Earth View to locate Rockstone and the nearest named place in the eastern direction of Rockstone, Linden. Used the Google Maps - Measure Distance Tool to measure between the approximate geographic center of the city of Rockstone (5.977029, -58.521328) and the approximate geographic center of Linden (6.008577, -58.307073), then halved this distance to find the approximate geographic midpoint. Used the Google Maps - What's Here Tool to find the coordinates of the approximate geographic midpoint between the two. Used the halved distance as the linear extent. Input coordinates, coordinate precision (.00001 degrees), datum (WGS84), linear extent (11975.0 m), and measurement error (10 m) into the MaNIS Georeferencing Calculator to find the uncertainty radius (according to the Georeferencing Quick Reference Guide, Offset: Direction only, no distance).
