    3434   * Enter the output Range offsets into the range corrections dialog of ALSPP. Only need R1 for A and B for now.
    3535 * Uncheck the BIT mode data (we don't need to process this) and run the ALSPP processing
    36  * Look at the filesizes of the output data.  If the LAS files are over 400MB in size then Attune will not run. If this is the case re-process with only the part of interest of the line.
     36 * Look at the filesizes of the output data.  If the ATN.LAS files are over 400MB in size then Attune will not run. If this is the case re-process with only the part of interest of the line.
    3737   * Part of interest will be the area where all flight lines overlap.
    38 3. Ground classification needs to be performed on the files before tie pointing in Attune.
     383. Ground classification needs to be performed on the files before tie pointing in Attune. But to load the ATN.LAS files into Terrascan we need to first import them into Attune to convert them. To do this follow the first step of 4. below and import the .bin files into Terrascan.
    3939 * We do this so that we only use points on the ground in the tie pointing (since we don't want errors due to perspective or shadowing)
    4040 * Ground classification procedures can be found [wiki:Sensors/LeicaLIDAR/MashUp#Groundclassification here]
