:good:
I am about to process in Civil3D your posted point data but you're flooded with solution already. 🙂
The concept is you need to create two TIN or Grid surfaces (base surface and top surface) to define the boundary conditions. You then create a volume surface using the two predefined surfaces.
This is what I like in this group. Very lively, very helpful, and very responsive.
Merry Christmas to everybody..
Regards.
> have never created a TIN in real life. Florida is FLAT... like the top of this his is 60' above sea level, I thought I was going to run out of oxygen. So, while i understand the concepts you all are mentioning, I have no clue how to ACTUALLY do that.
Can you calculate the volume of a pond? Being in coastal waters I'm betting the answer is yes. Turn your pile upside down, it's the same principal.
Here's my numbers...
Are we sure of these results?
An unit of measurement was not mentioned. What if the job was surveyed with le système international d’unités? The good old metric system...

Not to be rude
"I have no clue how to ACTUALLY do that."
So why on earth are you trying to?!!! Sometimes its best to just say no!

Excellent Post Andy.
Here's my numbers...
With a whole bunch of different numbers to use, and views, and pictures, and software results...7057 on the one, 4 results agree within 50cyds. The other pile however is 4232, and most differ by 200 cyds in the results...wonder what a cyd is worth. Think a big ole "plus or minus, or more or less, maybe!!" Or more shots and a good DTM. Used to do lots of coal piles for quanities, they were not fun because of how the pile runs when you try to walk on the stuff. Same deal with clay on a landfill cap after a rain...a little slipery.

Ladd's NE pile calcs differ because he didn't use breaklines along the "shelf", and instead connected all the higher points. He probably did his before the photo was posted. The results are pretty close, though, for the NE pile. I've never done this before either, although I've created a lot of TINs. Cool post.
Here's my numbers...
I think I'm like Andy, with an old Geodimeter 600 (non reflectorless). But this seems like a good job to use reflectorless on if you have it.

Agreed, but most likely somebody in the scanner world would offer an even better methodology. Unlikely they'd like the bill, but would be a perfect application.
Me, I just stick to good old Mr Robot and take a gazillion shots in trak mode. Hopefully find a hill about 300' away and you're good to go
wow, thanks again
I do love this place!!!
and as to why would I do this.. Why not? Heck, I used a pentagonal pyramid and came up with dang near the same volume as Randy on the big pile.. How else would I learn anything new? I work alone, and I don't think the dog understands volume calculations. I'm sure a more detailed measurement would have tightened up the various outcomes.
re payment, I'll buy the first beer here on island for all responders! (even the guy who thinks I shouldn't have tried)
thanks everyone for the numbers and the lessons!

Correct on both counts (I guess the old "a picture is worth a thousand words" statement is true 🙂 ). When I applied proper breaklines and re-created the models, my numbers started to gel better with the others:
>SW: 4,340.3 C.Y.
>
>NE: 7,080.4 C.Y.
I also made an educated guess and snapped this picture of what I believe to be the proper geo-referenced location of the piles:
Good stuff.

wow, thanks again
Now that you have some answers...ask the guy with the excavator, the guy that delivered it to the site, or the guy that is gonna buy it, what sort of number they came up with, just rough of course( because they will hold you to it later, when somebody runs short)???? I see Paden bailed yesterday!!! Busy today I hope!! Maybe someone else noticed the picture does not reflect in the cad reps???

Amazing effort, Ladd! This is the middle school continuation of a grade school project I did a few years ago. Very cool!
wow, thanks again
Oh my, doesnt anyone have decent clients that understand what a rough estimate is anymore? I swear if my client ever comes to me and bitches about the numbers I gave him I will NOT throw any of you "under the excavator" !! Relax! Really, first beers are on me, you puck the island bar!
wow, thanks again
What do you mean, the cad reps doesn't match the pix?
Andy
This is off topic, but does have to do with volume measurements. Several years ago I had the luxury of vacationing to Captiva Island, at a place called "Jensen's Resort" kind of on the North end of things. Pretty cool set up with individual cabins, a barbeque area, other low key things. The bay is on one side and the gulf on the other.
Then I heard that a couple years later a hurricane cut Captiva Island in half. I just wonder if that really happened, how did they fix things, and if Jensen's is still there.
Maybe you've worked around there?
