To use PDAL to assign a CRS to a las file, do the following:
- Open up a Command prompt. Type in the pdal command:
C:\> pdal translate -i input.las -o output.las --writers.las.a_srs="EPSG:32750"
Note: where a_srs is the option to assign a CRS e.g. EPSG:32750
- To double check whether the CRS tag has been assigned to the las file, you can use the lasinfo tool from liblas, as shown below.
