Is there a way to install pdal on Linux?
It does, however, offer you the ability to churn through points in many formats, and string together complex processing tasks easily. You can install PDAL on Linux, MacOS and Windows, using the conda package manager or docker or native installation. Please note that each prepackaged distribution has slightly different sets of plugins included.
