Unable to export classes larger than 31 #314

Closed kcotar closed 7 months ago

kcotar commented 1 year ago

In the latest version, we noticed that exporting classes larger than 31 is not working as before in 2.2.0. For the test, I have an input LAS 1.4 file with point format 7 with random classification values from 1 to 255. In the latest version, all points that have a classification larger than 31 are set to the fixed value of 1. This leads me to believe that the problem is not in throwing away some bits during some data-type conversion, but an actual value remapping happens.

Can this be related to my other problem with exporting LAS 1.4 data? https://github.com/connormanning/entwine/issues/313

Using entwine 3.0.0 (installed version, reported version is 2.3.0) and pdal 2.6.0.
