Google Earth for the Study of Ancient Civilizations

Satellite imaging is well known as a useful tool in many scientific disciplines and various applications. Google Earth, with its free access, is now - thanks to increasing resolution and precision - such a tool. It improves the visualization and dissemination of scientific data, and opens doors to new discoveries. For example, many Nasca geoglyphs are now visible to Google Earth and so are the orientations of Chinese pyramids, which appear to be laid out with the aid of a magnetic compass. Google Earth can also "see" a previously unknown "Monte Alban II" close to the well known "Monte Alban" in the Valley of Oaxaca (Mexico), as well as prehistoric causeways in Mesoamerica (namely, in north Yucatan) and in the Chaco valley, New Mexico. We find that Google Earth can save time and resources significantly: before, during and after field measurements.
