I reassembled a workbench to create 3D PDFs. They contain,
among other things, a surface and its contours. I run the workbench with a
batch to create PDFs of different areas. While doing this I recognized that at
the same geographic location the contours are not identical in different PDFs. The
differences in contours depend on the clipping area, because if it's the same
area, the resulting contours are identical. I use one LIDAR reader over all.

Has someone ever had the same trouble? Thanks for help!
:)

I have a workbench set up where I create a Feature Class inside a file geodatabase. the next step is to create the metadata and load it into the same Feature Class. This all works fine.

 

 

I'm doing the exact same thing with a zipped file geodatabase and it's giving me errors.

 

 Attempting to create table 'XXXXXXX' with 'geodb_type' set to 'geodb_metadata'. FME features of 'geodb_metadata' can only be written to existing tables. If intending to write metadata, please ensure the table already exists.  If intending to create a new table, ensure the 'geodb_type' is set to a valid table type. A fatal error has occurred. Check the logfile above for details
 I've checked all my parameters and they are the same between my zipped and non-zipped file geodatabase.

 

 

Any idea why?

 

 

Thanks

If your dataset ist not too big, you could create the contour lines of the whole area at once and then do the clipping in a second step.


Thank you for
your answer. DaveAtSafe, after your Input about the triangulation I generated
them as separate DXF Output so I had the possibility to compare. As expected
they are not identical. But the differences are not just in the edges, they are
all over the clipping area. The only way to improve my results is to define a
smaller Surface Tolerance in the TIN Generator. At the moment I am testing the
runtime that is necessary for different sizes of clipping areas and different Surface
Tolerances. But as you say whkarto, I think to achieve identical results the
best way would be a two step calculation.
