Omission in interpolation calculation Z_GROUND in PROFILE table

Omission in interpolation calculation Z-GROUND.

Although this remark is understandable, Ple4Win calculates the Z-GROUND values as intended.

IDENTS are linked to NODES. Defining G-LEVEL using IDENTS means input is provided for nodes 1, 12 and 23. The other nodes (2-11 and 13-22) will get interpolated values.
As nodes are always located on the pipeline axis, interpolation is done using the AX-L value of the nodes.


The resulting Z-GROUND of node 4 is 1654.710 leading to a soil cover of some 948 mm

Using X coordinates (0, 1000 and 2000 mm) as input for G-LEVEL the Ple4Win generated
Z-GROUND values will form straight lines, and results in a Z-GROUND of 1707.107 mm.

Of course we can discuss a different approach in the future.

Please refer to the screen shot.
