Map Coordinate System Overview

In Strater, map layers and maps can have an associated coordinate system. All coordinate systems defined by the map layers are converted "on the fly" to the map's target coordinate system. This allows maps with different coordinate systems to be easily combined in Strater.

The standard procedure for creating maps in a specific coordinate system are:

Create the map by clicking the Map | Create | Well Map or Map | Base Map command.
Click on the map layer to select it. In the Property Manager, click on the Coordinate System tab.
If the Coordinate System is not correct, click the Set button next to Coordinate System. The Assign Coordinate System dialog opens.
Make any changes in the dialog. This is the existing coordinate system for the map layer. When finished making changes, click OK.
To change the coordinate system for the map, click on the Map object in the Object Manager.
In the Property Manager, click on the Coordinate System tab.
If the Coordinate System is not correct, click on the Change button next to Coordinate System to set the desired target coordinate system. When finished, click OK.
The entire map is now displayed in the desired target system.

Strater does not require a map projection be defined. Maps can be created from non-referenced map layers, working in the same manner as previous versions of Strater worked to create unreferenced maps. If you do not specify a source coordinate system for each map layer, it is highly recommended that you do not change the target coordinate system for the Map. Changes to the target coordinate system for the map can cause the unreferenced map layers to appear incorrectly.
