[pdal] pdal translate cropping problem/question

[Stefan Ziegler]

Then I get:

PDAL: the argument ('([593000, 594000], [227000, 228000])') for option
'--bounds' is invalid


Looking at the source: pdal translate wants a BOX3D, the crop filter a
BOX2D. Is this the reason for this error message?

regards
Stefan
