Wow, glad to see that they have scanned those diagrams. I have quite a collection of them, it was really the only way to execute a control survey in the early days of GPS, there were no HARN, no CORS, no NAD83, and it was important to know how stations were connected together when all we had to tie in were triangulation/traverse stations.?ÿ
I worked on a number of projects where we would not get good closure between stations, and you could look at the diagrams and see that they were not connected together. There was one project in eastern PA where I found a 1 meter bust between first order stations, and it turned out they were in different triangulation chains.?ÿ
Things are so easy now...
