Data identifier: ZKOR [-] (only in 3D models, *.3d)

This identifier is used to enter the Z-coordinates of the deeper node layers in the *.3d file. The node numbers do not include offset (3DNR), but are rather specified as equivalent to the nodes in the uppermost layer. The 1st ZKOR data block in the 3D file is used to assign the Z coordinates of the 2nd node layer, the 2nd ZKOR data block in the 3D file is used to assign the Z coordinates of the 3rd node layer and so on.

The number of the node layer for which the layer heights are currently being defined is therefore always one higher than the number of the corresponding ZKOR block. The elevation of the top node layer is provided from the data in the model file, which can be either from the terrain elevation or the initial potential heads.

Example:

ZKOR (2nd node layer)

22.53 1- 125, 235,

23.11 126, 154,

ZKOR (3rd node layer)

16.27 1, 5,

16.08 2- 4, 25

If the 3D number offset is set to 10,000, the node with the number 10001 (2nd node layer) has the z-coordinate 22.53 m and the node 20001 (3rd node layer) has the z-coordinate 16.27 m in the above example.
