If this for the dock/lake thing, you could measure the height of your eyeball from the ground, then stand at the water's edge (today at 1056.43 msl) and use a level to sight a point on the ground toward the dock, move to that spot & do it again. etc... poor man's surveying kit. The lake level is very accurately measured every weekday. Get it at 770-945-1467.
Did that read like a joke? It's my impression that a GPS altimeter, a barometric altimeter, or even the hybrid kind are only accurate to tens of feet– probably not very useful for a dock/lake level issue. For real accuracy, you want a surveyor. I was describing a dirt cheap way to get it pretty close. I have a digital (barometric) altimeter that reads in 10' increments if that will help you.
I have been reading up on gps and I am not having much luck in regards to measurments to sea level.
Your way may be the best. I had no idea that the accuracy could be off by 10 feet. Makes me think that I had better double check any method that I use for accuracy.
The sight level using a long string over a distance would work but it takes two people and someone is going to get muddy. This may be what I end up using.
I wonder if I could use one of those electronic levels they sell at Home Depot.
Yes, I though you were joking until you mentioned the + or - accuracy of the gps. I thinkyou are probably right. I would want accuracy to be within inches not feet.
I'll do it for you cheap and guaranteed to within 6" accuracy.
We wouldn't want you getting all chilly or muddy-up those footsies– you just keep sailing in that warm wind and leave the dirty work to "the great unwashed".
I just talked to a land surveyor. He told me how to make a measuring device from a 4 foot level, a pair of binoculars and a stick with measurements on it.
Sounds crude but I think will will work just fine. Total cost is $0.00
Plus all gps' are inaccurate up to 10'. on sea level measurements.
Dave - one of the laser levels and a camera tripod will work well using the same technique described by Chris the Prankster. Just remember, Grasshopper, in the quest for humility - it does not matter how high you are, only that your feet touch the ground.

Thanks, Chris but.....................I don't think so.

Sill seeking a good method of measurement.

Maybe Maine and Texas have nothing to say to one another.
