The default coordinate system of the map and layers is NAD_1983_UTM_Zone_17N. To change it:
- Click the Options button in Home tab. The Options window will appear.
- Switch to GIS tab and select the desired coordinate system from the Default coordinate system list. Note that the GIS tab is not available without a valid ArcGIS license.
- Click the OK button to save the option. The new default coordinate system would take affect for the next new project. It won’t change the coordinate system of the current project.
