In order to create new maps you can use:
the Create Map link of the Maps menu in the navigation bar
the Create Map button in the Explore Layers page [Data menu > Layers] is greyed out - unavailable
If you followed the steps above, you have just created your first Map. Now you should see it in the Explore Maps page (Maps menu > Explore Maps], see Map Information for further details.
The Map you created is now available to everyone in your team. We will take a closer look at the Map Viewer tools in the Exploring Maps section.
