Large data sets need to be loaded in such a way that they use the least amount of memory possible. In the next section, you will load a prepared LiDAR import format from an IOP (Input/Output Parameters) file.

Note: If your data is in LAS format, many of the steps in the next section are not required. However, the corridor thinning technique is required for both formats. LAS format is the preferred format for LiDAR, as it is compact and loads fast.
