Cut fill app: what matters for field volume calculation
Cut fill volume may look like one number, but the data behind it decides whether it can be trusted.
Field takeaways
- Volume needs boundary and height data.
- Existing and design surfaces must share reference.
- Point density must represent terrain.
- Phone or DEM height is for reconnaissance, not final payment.
- MapLab Survey helps with preliminary cut fill interpretation.
The surface is the input, not the formula
Every app applies similar geometry. The difference between a defensible volume and a worthless one lies in how many points were captured and whether the breaklines were picked up.
When a field estimate is enough
To decide how many trucks you need tomorrow, a quick estimate on the phone is fine. To certify a payment item, it is not.
Document the result
Record the reference surface, the date and the method. A volume without that context turns into an argument as soon as somebody disputes the number.
Watch the calculation boundary
The volume changes with the polygon it is computed inside. Fix that boundary and store it with the result.

MapLab Survey handles RTK/GNSS point capture, drawing, area and volume calculations and coordinate conversion, then exports to DXF, KML/KMZ, GeoJSON, Shapefile, GeoPackage, NCZ or CSV. Capture, calculation and export work offline. Live NTRIP corrections and online basemaps need a connection.
Frequently asked questions

For preliminary checks, yes.
What is needed?
Boundary, height data and reference surface.
Is DEM volume precise?
Useful for reconnaissance, not final quantities.
Can MapLab Survey help stockpile volume?
Yes, for preliminary field workflow.
