STM cannot load pod-files

Hi Krister,

Is it possible that your POD files are already locked by some other applications or modules?

Also does the points in your POD files classified?

If you could provide us some dataset we would be glad to investigate further what is going on.

In the meantime a possible workaround would be to export your POD files to XYZ files and use the XYZ files to create the STM.

Thanks,

Mathieu

Hi,

The files are originally classified .las-files.

I've also  tried to export as xyz, recreate the pod-files from xyz. Still no success.

Attached is one .las and the resultning .pod-file.

Hi Kristen,

I tried with your pod file and it also failed for me. But I had success with the xyz export...

 I exported to xyz  from point cloud File export Ascii XYZ with 'Exclude' flagged on both intensity and Classification. (not sure if that made the difference)

/edit

Forgot to mention I used the xyz ascii file directly as the point source for the stm.

Mike

Hi Krister,

Thanks for the dataset.

It appears that there is a GCS in the .LAS file that is exported to the POD file and the WKT representing this GCS cannot be interpreted by MicroStation.

Actually a POD containing a GCS that cannot be interpreted by MicroStation is not considered a valid data source for a STM. Since this seems to be a bit too much restrictive, even more considering that the source GCS can be overwrite in the STM source option dialog, I have entered the TR 350436.

Note that there is actually no way to change the GCS information in the POD file or block the export of the GCS from the LAS to the POD file.

So the only workaround is to export your POD files to .XYZ files and create your STM file with those XYZ files.

Finally note that you can choose the correct position channels in the XYZ files when adding the XYZ files as STM sources (see below).

Thanks,

Mathieu

sorry Mathieu, can you explain the WKT acronym please?

GCS - global coordinate system

STM - scaleable terrain model

WKT - ?

thanks, Dan
