They can’t ‘google erf’ redact out modern structures?
Interesting.
Most visible structures are modern (year 1900 and newer) and sites of former structures are either medieval/early modern, or buried under layer after layer of subsequent occupation. This is mostly true in urban areas throughout the world, but Israel has much less ground with which to work. The Negev went from desert to farmland during the 20th century due to the continuous stewardship of pre-independence Israelis, but the amount of historic structures there is probably small, or very prehistoric.
