Description
This chapter delves deep into this widely used tool for virtual fieldwork and devises a strategy for independently assessing its accuracy. The author finds Google Earth Pro to be a reliable instrument with an accuracy that, depending on the spatial resolution of individual sites and the length of the line being measured, can exceed that of magnetic compasses.
