Blast2demPro error

[Martha Bostwick]

New to LAStools, and trying to understand this error I get when processing 4 LAZ files with  blast2dempro. I'm running this through an ArcGIS Pro 10.8 toolbox. It says Successful Completion of tool, but I have no resulting TIF images at the end, and there are a number of errors reported. 

Any help greatly appreciated.

Hi Martha,
We have a similar issue using blast2dem. We are getting the following error:

set_VerticalCSTypeGeoKey: look-up for 1127 not implemented
ERROR: unknown vertical EPSG code in '-vertical_epsg 1127'.
tin2dem usage error.

Did you find a workaround?

Hi Jean-Sebastien,

what does 

    lasinfo64 -i "<your_input_file.laz>"

say about your input file?

Who does your command you try to run look like?

If you want you can provide a link to your file and we will have a look.

Thanks,

Jochen @rapidlasso
