Hi,
I have a DEM raster which contains stockpiles I'd like to get a volume measurement on. These stockpiles sit on a flat pad, which I unfortunately do not have a DEM raster of. My current workflow plan is to create a copy of the raster, clip out the stockpiles, fill in the gaps to create an assumed 'flat' plane underneath the stockpiles using 'Elevation Void Fill', and then subtract the difference between the original DEM and the modified DEM.
I'm currently experiencing two issues:
1. I'm not sure I'm following the ideal workflow
2. My current workflow is producing odd and unusable results
I'll go over my current workflow issues, but if anyone can suggest a more suitable workflow, that would be even better.
1. I create the boundary of the stockpiles to use in the clip tool
2. Data is clipped
3. Using 'Elevation Void Fill' the gaps are filled in. The data looks fine, but when queried the majority of the data is showing as NoData.
4. In an attempt to force the NoData to actual pixel values, I export the raster as a TIF. The NoData issues disappears, but is replaced with the below data. Obviously this isn't ideal and I'm wondering what happens to produce this when the above result 'looks' to be fine?
So, what is going wrong here? Am I way off in the workflow I should be following? Any help is appreciated.
Regards
Nathan
