MrSID MG4 LIDAR Import

The Import MG4 Files dialog provides the ability to convert MrSID MG4 files into LAS Files or Shapefiles.

Unlike the ASCII Import Wizard, which involves 4 steps, this dialog simply requires you to select the MG4 files for conversion, an output folder to write the converted files to, and an output format (LAS Files or Shapefiles). 

Importing to a specific LAS File Version

You also have the choice to select one of several LAS file versions to create. Not all point attributes can be imported with each LAS file version. For example, the red, green, and blue color fields can only be imported when version 1.2 or later is selected. To learn more about the LAS file format, go to www.asprs.org/LAS_Specification.

How to Import MG4 Files

Adding MG4 Files, Selecting an Output Path, and Selecting an LAS File Version

  1. Open the Import MG4 Files dialog box by clicking the LP360 button on the LP360 toolbar and then Import -> Import from MG4 Files. (In LP360 for Windows, click File -> Import from MG4.) The Import MG4 Files dialog will open.

  2. To select one or more MG4 files to import, click the Add button.

  3. Navigate to and select the MG4 files to import and click Open. 

    Tip  Use the Ctrl or Shift key to select multiple text files to import.

  4. To select an output folder to write the new LAS files to, click the browse button (...) next to the box under Select a folder to write LAS files to. 

  5. Navigate to the folder you want to create the LAS files in and click OK.

  6. Click the arrow on the LAS File Version box, then select the desired file version for importing the text files. See the "Importing to a Specific LAS File Version" above for information about the different LAS file versions.

    Note  A warning may appear if you select fields that a file version does not support. You can cancel the selection or continue and set the unsupported fields to Unknown.

  7. Click Finish to start the import process.

Removing MG4 Files (optional)

  1. In the list of MG4 files, click the file you want to remove. Use the Ctrl and Shift keys to select multiple files in the list.

  2. Click the Remove button to remove the selected file(s) from the list or Remove All to remove all of the files from the list. The files are immediately removed from the list.
