Finding area of stock piles

Hello,

 

I went out with our GPS and shot each of our stock piles we have in our yard (recycle asphalt, 3/4" gravel, 1" gravel, etc.), and now I want to figure out how much of each pile we have

 

So what I did was create a seperate surface for each pile, then I created a volume surface for each as well and just set the base and compare surface as the existing, that wat was I can get the total sq ft of each pile, but now I want to figure out how much yards of material are in each pile

 

Would I need to set up a materials list for each on to calc how much are in each pile according to what type of material they are??  Or what would be the best way to go about it??

 

Thanks

On the menu bar choose Utilities---> Volumes dashboard.

 

Then create a new surface name it to the material type and select the base and comparison surfaces

it sounds to me like you already have something that will give you the yards. You did say you created volume surfaces comparing the stockpiles to existing ground. That is where you look to get the cubic yards of material.

If I follow correctly, you are comparing the same surface to itself.

 

Use the toe shots of the piles to create a datum surface, and then compare datum to existing. You need the bottom of the piles and then the piles to properly compare.

The original poster already mentioned that they also have a existing surface to compare to before the stockpiles where placed.

This is the way I read it as well

Setting the same surface as base and compare will give 0 volume. I chose to read it literally.

First, I created a EG surface, just ground shots throughout the sight, and the shots around the base of the piles ( there are 10 piles of material).  Then I created 10 surfaces, 1 for each pile, and I used the shots around the bottom edge as my boundry.  Then I created a Volume surface from each pile, Base surface being my EG and the Compare surface being each seperate pile ( so 10 total Volume surfaces).

 

But, as you stated, I get the total SQ FT of the pile, thats it.  Im looking to get the yard of material in each pile.  Do I need to set the material type in order to do this??  I guess Im not sure how to go about it with out creating a corridor and proposed contours so I can compare it?

So you took shots around the base of the piles? 

 

And how many shots did you take on the top of the pile? If none, try again. and think about how to make a volume.  You need three dimensions.

Maybe this will help...here is what I have.  I attached my base drawing....let me know if it doesnt work

How are you getting the area reported to you, in a table, on the command line or something else?  Try opening the properties dialog for one of your Volume surfaces and switch to the Statistics tab.  Can you see any areas or volumes listed there?

Im using the Volume Dashboard to get he SQ FT of the piles.  I added my Volume surface to the dashboard.

In the drawing it your EG includes your piles, so comparing EG with each pile will show no volume.

You need to create the EG without the pile shots and then compare the individual piles to EG as you have done.

Also - all of the volume surfaces are comparing the Pile surfaces to themselves, so no volume can be calculated.  Once the EG has been fixed all of the Volume surfaces should be deleted and recreated so that they compare EG to each Pile.

 

Edit - It looks like you already have survey figures defining the footprint of each pile.  If you remove the point group from the EG surface definition, so that only the figures are used then you should have a clean TIN under each of the piles that would give a proper volume.

Ahhh....I thought I had the EG surface by itself at one time, not sure what happend??  Got it now, Re-did the EG surface to only include GS and the base of each pile, then re-created each Volume surface, now Im getting the amount of Cu yds for each pile

 

Thanks guys

Your EG(1) appears to be made up of the piles also, so the surface volume is zero.

Create a new EG with only points on the flat part of the site.

Then create volumes using the new EG and the Pile(s) surface.
