# LAS/LAZ Pointcloud

* To Export a desired pointcloud in your Project into common mapping formats such as LAS or LAZ, click the “Export to LAS” button.

{% hint style="success" %}
You must first [create a .cloud file](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/create-a-cloud/create-cloud) in SpatialExplorer 6.0.X before exporting to LAS
{% endhint %}

* The Export Cloud to LAS window allows you to configure the various parameters associated with exporting the data

### Data to Export (Intervals to Fuse)

* This option determines which portions of the loaded trajectory will be exported to a LAS/LAZ file. 
  * The default option for this parameter is “All Data.” 
  * This will fuse the entire trajectory to the LAS/LAZ file and it will be the only option if you have chosen NOT to split the trajectory. 
* Otherwise, you can utilize [manual](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/create-a-cloud/manually-split-intervals) or [autosplit](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/create-a-cloud/automatic-intervals) trajectories to only fuse the portions of the trajectory that were split into intervals. 

### Output Coordinate System

* Click the "..." button to the right of "Output Coordinate System" to search for and select an output CRS. 
* By specifying the CRS, SpatialExplorer will transform the pointcloud from the project datum to the user specified output CRS.

* Select desired horizontal CRS, vertical CRS, units, and Epoch and then click "OK"
* **Note: If your vertical CRS is in orthometric heights, the "Select..." button will appear.** 
* **Click on the "Select.." button to download/select a geoid model** 

![](/files/-M_7WZY6edcvnfdnjFsW)

* Search for a geoid file name, select desired geoid, and click on the folder icon to the left of the name to download the file. 
* After the file is downloaded, the folder icon changes to a recycling bin icon.
*  Select the desired Geoid, and click "OK" 

![](/files/-M_7XrCkSULB1Kav_SW3)

* The geoid model will be displayed below the vertical CRS

* Configure the rest of the output parameters:
  * **File Version** 
    * Select output file version 1.2 or 1.4
  * **File Type**
    * Select output file as an uncompressed LAS or compressed LAZ
  * Options (Optional)
    * Only write Colorized points
    * Only write single-return points
    * Create one file per processing interval

    * Index of Interval starting at 0
    * Index of Interval starting at 1, with all curves set to 0
    * Index of LaserHead - Multilaser Scanners only
    * Range (using scalefactor) - Requires user specified scale factor
    * Zero
  * **Time Format**
    * GPS Microseconds
    * GPS Standard Time
    * GPS Standard Time (Adjusted)
    * No Time / Zero
    * Seconds in UTC day
    * Time of Week (seconds)
      * Recommend to be used with Phoenix LiDAR Terrasolid workflow
  * **Point Source ID**
    * Amplitude - Riegl scanners only
    * Deviation - Riegl scanners only
    * Index of Interval starting at 0
    * Index of Interval starting at 1, with all curves set to 0
      * Recommend to be used with Phoenix LiDAR Terrasolid workflow
    * Index of LaserHead - Multilaser Scanners only
    * Range in centimeters
    * Zero 
  * **Classes to Export**
  * Extra Bytes (Optional) - only compatible with version 1.4 output
    * store distance, amplitude, deviation, normalized height, sensor id, and laser id information
  * Manual Point Offset (Optional)
    * Specify an additional manual offset to be applied to the selected transformation
  * Trajectories (Optional)
    * Write Trajectories as LAS files
    * PointSource-ID
  * [Report](https://docs.phoenixlidar.com/lidarmill-desktop/post-processing/workflow-kk/export-cloud/reports#create-reports) (Optional)
    * [Write Project Report](https://docs.phoenixlidar.com/lidarmill-desktop/user-interface/toolbars/trajectory-cloud-reporting#save-report-tool)

* After configuring all parameters, SpatialExplorer is ready to fuse the data into a common mapping format file with the selected options. 

* This can be initiated anytime by clicking on the "OK" button at the bottom right.
