How can GPS technology be used to plot archaeological finds?
With the simple click of a button, a handheld GPS receiver can plot the National Grid Reference (NGR) of a findspot within just a few seconds: the procedure may vary as all handheld GPS receivers are not designed the same way (see examples below). How to record a findspot: • Stand above the findspot. • Record the NGR using the GPS receiver. • Mark a plastic finds bag with the NGR. • Place the find in the finds bag. Note: before recording findspots of archaeological finds ensure the GPS receiver is set to the correct ‘time zone’ (UK) and ‘map datum’ (British National Grid). Most GPS receivers are made by US companies and set to record Longitude and Latitude.
