Hi. First post under Benchmarking, but I've done a fair amount of reading and searching and haven't seen this addressed.
I was wondering if anyone is, like me, trying to complete a personal goal of finding benchmarks for each "Marker Type" category.
I'd never seen this mentioned, so I had to do my own searching for a reference, and I found a source at http://www.ngs.noaa.gov/FGCS/BlueBook/pdf/Annex_I.pdf which lists around a hundred different types (tower, stack, microwave mast, pipe cap, etc.).
I've personally found 30 different types so far, and combing these forums seems to be helpful for hearing about benchmarks with marker types on my "want" list. Or maybe I just need to learn how to search the NGS database for the more obscure types ("dolphin"? "rock awash"?).
