    Georeferencing Quick Reference Guide, Version 2012. Atkinson Field is now called the "Timehri Airport." Referred to Airfieldinformationexchange.org (http://www.airfieldinformationexchange.org/community/showthread.php?2335-GUYANA-Atkinson-Field-Timehri, accessed 8/7/2015) for locality information for Atkinson Field. Also referred to Geonames.org (http://www.geonames.org/maps/google_6.499_-58.254.html, accessed 8/7/2015) and found that Cheddi Jagan International Airport is synonymous with Timehri International Airport. Georeferenced to the approximate geographic center of Cheddi Jagan International Airport in Guyana. Used Google Maps – Earth View to locate the Cheddi Jagan International Airport. Used the Google Maps – What's Here Tool to find the coordinates of the approximate geographic center of the airport. Used the Google Maps - Measure Distance Tool to find linear extent by measuring from the selected coordinates to the farthest extent of the airport (determined through visual evidence). Input coordinate source (locality description), coordinates, datum (WGS84), coordinate precision (0.00001 degrees), extent of named place (1810 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: Bounded Area).
