Saving cloud as "las"

Post by guysadot »

hey

I'm trying to export cloud and save it as LAS file.
I've got those error (added image)

In advance I gave two different clouds (of the same area) the same coordinates (Israel ITM) with high level of accuracy about 1-2 cm, therefore they have integrate automatically.
later I merged them together and wanted to export as well.

What's the meaning of the error please?

Did both of the files had a 'scan angle rank' scalar field? If only one of them has one, then after the merge, the other points will have an invalid 'scan angle rank' scalar value assigned automatically. Which wouldn't be accepted by PDAL (the library in charge of saving the LAS file).

Either you can create this scalar field before merging (with 'Edit > Scalar field > Add constant SF', and set all the values to 0 for instance). Or remove the scalar field from the other cloud if you don't need this field.

And the other error is probably related. But if it is not, try saving the file to a path without any special character.
