[time-nuts] TBolt self survey
lists at cq.nu

GPS altitude is a bit different than map altitude. There is a recent thread
if you want all the details of why. Once you do the self survey, just accept
what ever it comes up with for altitude. If it's off by 100 meters, just
accept it and move on.

self survey puts my house (AFAIK ~920M ASL, 13N 77.35E) in the Pacific
ocean, south of Vancouver and west of Seattle and about 10 meters under
water. I am doing something wrong for sure!
