Available in all license levels of LP360.

The Coordinate System Utility dialog allows you to set the Coordinate Reference System (CRS)*, of a project or output file and shows descriptions of selected coordinate systems. You are able to select from predefined horizontal coordinate systems or select your own from a file. You are also able to select from a number of predefined vertical datums. This allows you to insert the correct WKT or EPSG in the LAS header. When instantiated by the Coordinate System Utility , this dialog may be used to create PRJ files containing coordinate system and projection information for use in other workflows.

*Aka Spatial Reference System (SRS) because it usually contains both horizontal and vertical coordinate systems.

How to use the Coordinate System Utility

1. In LP360, select the File menu and then Coordinate System Utility or the Coordinate System Utility from the Project Tab of the ribbon.
2. The Coordinate System Utility dialog will open.
3. Set a Horizontal Coordinate System.
   1. 1. To use a predefined coordinate system, select the radio button for 'Select from Predefined Coordinate Systems', then navigate inside of the Horizontal Coordinate Systems box to the desired coordinate system.

Note: To use an Authority Code, simply enter a valid EPSG/ESRI code greater than zero into the box and press 'Find in List'. This value will be populated automatically upon browsing to and selecting a horizontal coordinate system in the upper right box.

1. 1. 2. To use a coordinate system from a file, select the radio button for 'Select from File', then select the ellipsis (...) to navigate to the file.

4. If desired, set a Vertical Datum using one of the datums in the 'Predefined Vertical Datums' box.
5. Once you have set your coordinate systems, you can use the 'Save PRJ' button at the bottom of the dialog to create a PRJ file to contain your coordinate system and projection information.
6. Press 'Close' when you are finished setting the coordinate system.

TOC Right Click Menu SRS Tools

After setting the Project CRS in the Project Settings dialog, if the user selects the following commands from the TOC Right Click Menu:

Set Layer SRS (using Project SRS)

 The current Project SRS will be copied to the layer SRS.

Set Project SRS (using Layer SRS)

The current layer SRS will be copied to the Project SRS.
