I frequently need to calculate the volumes of stockpiles, and occasionally there is vegetation overhang or other anomalies obscuring the base of the piles in the DSM. In these locations, I would like to import surveyed points as a shapefile, and use these points as vertices to define a base surface in Pix4D.
When I attempt to “Import Base surfaces” in the volumes tab , I keep getting the error:
“Error e0202a: Could not import volume(s) from SHP file. The selected file has to contain the 3D surface of the volume measurement(s).”
These surveyed points are a 3d shapefile in the same coordinate system at the Pix4D output, so I’m not sure what’s causing the error. Is there a certain shapefile format that Pix4D prefers when importing base surfaces that I’m missing?
Additionally, I’m running into an issue when exporting base surfaces. The attributes in the resulting polygon shapefile are disregarding the names I have assigned in Pix4D, They show up as the default Pix4D naming convention (Volume 1, Volume 2, etc.)
