Accurately dating an archaeological site requires the application of two distinct methods of dating: relative and absolute. Many researchers working around the ancient Maya city of Copán, Honduras, have located tree ring dating and archaeology of small rural villages and individual dwellings by using aerial photographs and by making surveys on foot. When a date is quoted, the reader should be aware that if datiing is an uncalibrated date a term used for dates given in radiocarbon years it may differ substantially from the best estimate of the actual calendar date, both because it uses the wrong value for the half-life of 14 C, and because no correction calibration has been applied for the historical variation of 14 C in the atmosphere over time.
