Coordinate System Utility

The Coordinate System Utility dialog allows you to set the coordinate system 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. From this dialog, PRJ files may be created containing coordinate system and projection information for use in other workflows.

How to use the Coordinate System Utility

1. In LP360 for Windows, click the File menu and then Coordinate System Utility. The Coordinate System Utility dialog box will open.

2. Set a Horizontal Coordinate System.

a) To use a predefined coordinate system, click the button for 'Select From Predefined Coordinate Systems' and then navigate inside of the Horizontal Coordinate Systems box to the desired coordinate system.

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

b) To use a coordinate system from a file, click the button for 'Select From File' and then click the ellipsis button (...) to navigate to the file.

3. If desired, set a Vertical Datum using one of the datums in the 'Predefined Vertical Datums' box.

4. 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.

5. Hit 'Close' when you are finished setting your coordinate systems.

TOC Right-Click Menu SRS Tools

After setting the Project SRS in the Project Settings dialog, if the user selects the 'Set Layer SRS to Project SRS' command from the TOC right-click menu then the current project SRS will be copied to the layer. Selecting 'Set Project SRS to Layer SRS' will do the opposite.
