• Compute depths using the HyperCUBE super-grid: The HyperCUBE super-grid is creating a grid based on several hypotheses from the depth data. In addition to the depth grid this algorithm can also create the attributes DepthHypotheses and HypothesisStrength as output in the cube_depth_surface. 

Grid increments

 Specify the increments:

• X Increment (m): Specify the increments in X-direction (Easting) for the result grid.
• Y Increment (m): Specify the increments in Y-direction (Northing) for the result grid.

The lower left corner and the upper right corner of the result grid will be rounded down and up to contain the increments. (A 5 meter grid increment result in a lower left corner starting on an integer value of 5 meter.)

Error Distribution Model Algorithm

the gives information of which surface the command is started from. Select a Poly Data or Structured Points (surface) data set in the project and click the Image Removed button beside the text field. 

When starting the volumetrics with a Poly Data set as input, the ply data will be triangulated to a surface model. The better the polygon describes the actual cut surface the better the result the volumetrics calculation will be. The surface created from the poly data is named as the Cut surface.

The calculation of the volumes is done by subtracting the cut surface from the Terrain surface to get the difference surface.

Output

Select options for whatCreate the cut surface from polygon data set.

The surface is saved with the name CutSurface in a subfolder named Volumetrics in the same folder as the terrain surface is located

Output

Select options for what output to create.

• Depth Surface: The depth surface will always be produced in the cube_depth_surface result data.

• Uncertainty Surface: When the depth estimation algorithm "Compute depths based on nodal estimate algorithm" this option can be checked. The Uncertainty values will be an attribute in the cube_depth_surface.

• Number of Hypotheses Surface: When the depth estimation algorithm "Compute depths using the HyperCUBE super-grid" this option can be checked. The DepthHypotheses values will be an attribute in the cube_depth_surface.

• Hypothesis Strength Surface: When the depth estimation algorithm "Compute depths using the HyperCUBE super-grid" this option can be checked. The HypothesisStrength values will be an attribute in the cube_depth_surface.

The Results

After executing the volumetrics a dialog will pop up showing the parameters, result and volumes from the calculations. The report itself is saved in the project structure in a folder named Reports under the same folder as the command is executed from. The report itself is named as YYYYMMDD CUBE (the name of the executed command).
