Google Earth for elevation

Google Earth elevations ARE NOT ACCURATE ENOUGH for anything that requires specific elevation data.

Google Earth uses the digital elevation models (DEMs) which is available and they will either be 10 meter or 30 meter resolution elevation models.  Folks, that isn't even close to accurate enough for sandbagging purposes.

Just want people to know that are in Bismarck.


 

Don't get me wrong, it gets you ballpark but thats about it.

I know this is more of a talk forum for elevation outside the flood areas (or it seemed as it related to Tobacco Gardens).  But with that said, I thought I'd post this from a PM a fellow member sent to me.

I know Bismarck has the data but to access it was difficult.  They apparantely did this data creation as a crude way of doing it.  Or maybe it isn't a crude way, it actually is very helpful.

Here you folks go living down in the Bismarck area.  I was told this is comprised of LIDAR data so it should  be good to go.  I am not responsible for that...it is up to you to ensure that it is indeed LIDAR.

Thanks for the info because what I was looking at just wasn't making sense, or at least i hoped that was the case. I couldn't figure out why they were sandbagging when they are supposed to be above 1854 ft plus these lake homes were there in '97 and stayed dry. According to google all the places in question are sitting at 1847 ish making 1854 basically right up to the doorstep of the TG restaurant. What one guy involved told me last night is that they are worried about in inflow pushing water levels up above where they once were as it goes by. I don't know how much that is a possibility, just what i was told. But anyway I'll just keep using google earth  for just getting the jist of things and most importantly for finding access to fishing spots.

It should be easy to figure out property that will need to be sandbagged at Tobacco.  The lake got to the highest point it could in 1997.  If they didn't sandbag then, they don't need to now.  The lake cannot get any more full than what it did in 1997.  If there was more development since then (which I suppose there was) people can still do it by using a level.  Stick a stake at the water line with 1 foot increments.  Go where they will think they need to sandbag and setup some type of system that will give them a shot at the stake.

Think I'll just leave it at that.  I don't want to be responsible.  I know a crude way of doing it but in all honesty it should be easy to figure out as the water level is currently at 1852.40 and the lake can go no more than 1854.4 so I guess do the math.  That's two feet and you should be able to figure out or eyeball two feet by using crude ways of "level" shooting.

Kind of redneck surveyeing...
