Hello,

 

Please can someone help me with this very strange issue i have encountered with the RasterDEMGenerator transformer.

 

I have uploaded some sample data and the sample workbench. The input features have 40 vertices to pass through to the RasterDEMGenerator but it fails each time, whereas when i add in another transformer - PointCloudCombiner before the RasterDEMGenerator it works fine.

 

I need to get to the bottom of this issue as i cannot use the PointCloudCombiner transformer.

 

Many thanks

I have not checked your data yet, but what is the grid distance of the vertices and what is the cell size in the RasterDEMGenerator?

The vertices are spaced every 10m or so, and the cell size is set to 2m so this shouldnt be the issue

The coordinates in your dataset have 9 decimals, which is extremely small in meters. Rounding the coordinates to mm (3 decimals) got it working for me.

 

As an alternative, changing the Surface Tolerance from 0 to something really small worked as well.
