Dan:
The courses which have been mapping their greens for the longest time include Augusta National, Winged Foot [they had topo maps of the greens in the '74 US Open program], and Royal Melbourne [done by the Royal Melbourne Institute of Technology].
Unfortunately, in all these cases, the maps have been used to make alterations in those greens, though we did try to use the old map of #6 East green at Royal Melbourne as a tool to help restore it in its new location.
The more I look at old greens, I'm convinced that I can see that they change, quite predictably, over time, due to sand topdressing and superintendents tweaking the topdressing to deal with difficult areas.
Trees are another area of interest. Only a few clubs I've worked with have documented the trees they planted. At Chicago Golf Club, the superintendent in the 1970's and 80's was meticulous in noting wherever he planted trees ... when they gave me the list, they thought I was kidding when I handed it back to them and said, "There's your list of what to take out!"
