# Target Coordinate System - Map

Maps can be displayed in any coordinate system. The map is displayed
in the coordinate system defined as the Target
Coordinate System for the map. A coordinate system normally has
a defined projection
and datum. If some map layers are using a different
source coordinate system than the map's target coordinate system, the
map layer is converted to the map's Target
Coordinate System. The map's Target
Coordinate System is the new coordinate system that you want to
use to project your X, Y coordinate data.

When a new plot is created, the plot and layers of the plot are set
to an unreferenced coordinate system.

##

## The Coordinate System Page

The Coordinate System page is
located in the plot properties.
Pin maps have a separate
data coordinate system. Edit the Data
Coordinate System in the Coordinate
System page of the Property
Manager for a pin map.

Specify the map coordinate system on the Coordinate
System page.

### Coordinate System

Click the Change button next
to Coordinate system to open
the Assign Coordinate System
dialog. This dialog lets you set the desired target coordinate system.
This is the coordinate system in which you want the map to be displayed.

Projection and Datum information is displayed
for the current Target Coordinate
System on the Coordinate
System page.
