Dataset Coordinate System Information

If no input coordinate system information is entered for a dataset, then MapLink Pro Studio will assume that the data is in Lat/Long and using the WGS-84 datum.

When the dataset is not in lat/long, an input coordinate system for the dataset needs to be applied by doing the following:

• Select Dataset | Input Coordinate System

This takes you to the Dataset Properties/ Coordinate System page.

From this page you can access the following:

• The Coordinate System Browser - This enables you to view details of all the available coordinate systems and select one for the dataset.
• The Coordinate System Viewer - From here you can view/ edit details of the currently selected coordinate system for the dataset
• The Coordinate System Wizard - This enables you to create a new user defined coordinate system.

To carry out the following operations, please see the appropriate sections:

Selecting a pre-defined Coordinate System
Creating a new user-defined Coordinate System
Viewing/ Editing the current Coordinate System

Where a datum transform is necessary, MapLink Pro Studio will automatically select an appropriate one. To override MapLink Pro Studio's choice of datum transform, do the following:

• If you have not already done so, select Dataset | Datum Transform
• De-select the 'Always use the default Datum Transform' box
• Browse through the datum transforms and make your selection
