Book: From the Ground to the Sky
Chapter: 6. Notes on the Accuracy of Google Earth Pro Heading Information for Archaeoastronomy and Landscape Archaeology Studies
Blurb:
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.
