Dear Listers,
I have a set of about 2000 underwater structures in rivers and streams
spread across seven states for which I need to gather x, y, & z coordinates.
The x and y I know how to get, but what would be a good way to get the
elevation above mean sea level at the top of the structure? The depths
would be relatively shallow - less than 50 feet - so I don't need deep sea
gear, but I can't stand on these structures, either.
Anybody have any experience gathering underwater elevation data, or
suggestions?
Please reply directly to me, and I will summarize the response in case
anyone else is interested.
Thanks,
Carolyn
