I've heard it mentioned that Tom D has a special memory for detail, sequence and recall of golf holes or courses that he has previously played......I can appreciate that as I have a similar skill that I will try to describe that was innate in my person but honed by use.
I am self taught in almost all that I seem to make a living by, so this particular skill came the hard way and I could not teach it to others....hell, I am going to have a hard time describing it at all.
I suppose it involves what some might describe as a 'photographic' memory but I would describe it more as an imprint memory skill .....
I can look at and while doing so almost scan a topo sheet, survey or aerial that once I 'load' or notice its detail, I have the ability to see this again in my minds eye.....eyes closed or even open [I try to not use this zone much while driving, but hey, if you ever hear of a wreck of mine where I left the road for no apparent reason, well now you will know the rest of the story].
But the loading part is only part of it as I can fully minipulate, explore options, solve problems, basically design in detail in my head......I can see details and colors, numbers, read wording etc......I can redraw on paper and at a fairly close scale these same elements if nessesary .....I can flip to a certain part and 'zoom' in at times, but the main thing is that I can remember enough to be able to design from in my minds eye, then I just download it later when I get to paper...oh and it also comes in handy on site exploration, I'm never lost because I've got the map!....I hope you get the picture, as its not easy to convey unless you are in here
Not only is it usefull for GCA but also for conceptual landplanning, which I seem to be doing alot more of lately, not that I nessesarily want to.
...maybe you all do this too [except for TP who has eliminated himself already....pity really, but he does write so well instead.]
