The elevation at my office is 406.
In the past year I have worked at elevations ranging from 11 to 6300.
The office floor, at home, about 180', the sea about a mile away in 3 directions. I was surveying at the last spring tides at -12', for a cable landfall: drysuit and wading in the sea up to armpit level with the dc clamped way up on the rover pole. That got the hydrographic surveyor confused, he's doing the subsea survey, 'I didn't know you had a boat and a sounder!'
-232 feet (open sky, guess where) to about 14,000 feet in Alaska. Ground to grid difference was easily measurable with a 100' tape up that high and the theodolite was much heavier, too.
average around 4500', low end about 2800', high end around 9000', have been above 10.000 some, not much
Around 3000' in West Texas.
570'-620' around Fort Worth
700' in North Dakota
and 1150' in Oklahoma.
South Louisiana
-5 to 15'
Little Rock, AR at 335 feet
DDSM:beer:
From 0' in the Meadowlands to a little over 1,000' in the Highlands. The office is at about 270', that's probably the average.
When they put a potato ridge on a levee it goes up to 18'
🙂
117' on the "Great Sandy Ridge" of Florida. In north Marion county.
The ridge runs from approx Valdosta, GA through Lake City, Gainesville, Ocala FL petering out south of Wildwood, FL.
> Surveyed interior CT (Waterbury area if any of youse are familiar with CT). Was at elevation 455' according to the GPS.....for a guy who surveys at elevation <100', it was no wonder why I was having a hard time breathing 😉 o.O

...just checked my log book. I did a survey in Sydney Inlet, British Columbia, on the wreck of the Lord Western (1853) in -85fsw, with a bottom visibility of 5 feet. I was using the SHARPS underwater mapping system on this one. The radio came to life telling me to get my ass back on deck just as my reserve air alarm went off - so, breathing??? I had to think about every part of every breath during my climb to the surface. When I finally reached fresh air, there was a TV news camera pointed at me and a reporter IN THE WATER!!!! Give me a freakin' break. I watched the news broadcast and fortunately for my professional pride it didn't appear to viewers that I was actually drowning.

In Portland you will as often as not be clinging to a cliff at 200' ASL. In Oklahoma, the panhandle is at 4000' and flat as a board.
About 650' here in the Riverina in NSW, Australia.
The highest point in Obion County, TN is the landfill at about 552' LOL. My office is 340'

I think we should start calling new datums thus: "LOL DATUM 2014".
Confuse the hell out of the general public, job security, right?
