I am trying to use the LAScatalog engine and clip out several thousand point clouds using a shapefile. I have already run this successfully but I specified my output names using {XCENTER}_{YCENTER} which as I have come to find out isnt the best option for me. What I want is something very similar to the documentation where {_LAKENAME1} was used, in my case this will be {shotnumber} as per my file. Unfortunately, it does not recognize this name within the file and thus cannot use it as a naming convention. Any help would be greatly appreciated.
