Create Projected Coordinate System
Feature Description
The Coordinate System Settings dialog supports creating new projected coordinate systems.
Feature Entry
- Start tab->Data Processing group->Projection Settings->Projection Settings window->New Coordinate System->Projected Coordinate System.
- Workspace Manager dataset context menu->Properties->Coordinate System option's Reset Coordinate System...->Projection Settings window->New Coordinate System->Projected Coordinate System.
- Map context menu->Properties item, in Layer Properties panel->Coordinate System option's Reset Coordinate System...->Projection Settings window->New Coordinate System->Projected Coordinate System button.
Steps
- In the Coordinate System Settings dialog, click the New Coordinate System drop-down button and select Projected Coordinate System.
- In the Create the Projected Coordinate System -> Set the Geographic Coordinate System dialog, configure parameters including geographic coordinate system name, EPSG Code, datum, reference spheroid, and prime meridian. For detailed parameters, refer to Custom Geographic Coordinate System.
- After completing parameters, click Next to proceed to the Create the Projected Coordinate System -> Set the Projected Parameters dialog. Configure the following parameters:
- Projection Type:
- System predefined projection type: Click the drop-down button to select from predefined projection types. Parameters are fixed and uneditable when using system-provided types.
- Custom projection method: Enter a new projection name in the combo box to create a custom projection with editable parameters.
- Projection Parameters:
- False Easting and False Northing prevent negative values in GCS, mainly used for Gauss-Krüger, Mercator, and UTM projections.
- In conic projections: Use single standard parallel for tangent cones (set both parallels equally) or two standard parallels for secant cones. Set central parallel as southernmost latitude line.
- Parameter units: Choose between "Degrees" and "dd:mm:ss". Check "Display in 'dd:mm:ss' format" to switch units.
- Projection Type:
- After configuring parameters, click OK to complete the creation.
