Lynn Brant: You could also direct your enquiry by e-mail to an acknowledged historian of surveying - Mr J.R. Smith (e-mail: <mailto:[email protected]> [email protected]) - who is a long-serving member of FIG. For more background see: <http://www.fig.net/hsm/index.htm> www.fig.net/hsm/index.htm ; here you will learn of the International Institution for the History of Surveying and Measurement ("A Permanent Institution within the International Federation of Surveyors (FIG)"). (Mr) Francis Herbert [email protected] -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Lynn Brant Sent: 23 August 2010 13:23 To: [email protected] Subject: [MapHist] request for information on ancient surveying I am trying to research whether the following scenario is/was possible and would appreciate any insight. First, we are talking about the 14th century, mid to late 1300s. The contention is that something was buried (no not treasure, perhaps a land claim) and that to mark it for a future party intersecting lines were drawn to mark the spot. The spot is on the side of a small knoll. There are six very large boulders with chiseled holes (I'm curious about that too). When these three pairs of boulders are connected with lines by gps, all three lines intersect over the target spot. My question is, at that time, how would a party have drawn such a grid? Would they not have needed a line of sight between each pair of boulders? The first line would have been easy, just find two boulders (there are many) that connect across the target area. Then find a third boulder and sight to a 4th such that that line crosses the first at the desired point. But the third has me puzzled. The boulders were too large to move (car size). How could this be done? Thanks in advance!
