Using the I3 Connectivity Explorer

Tips for using the I3 Connectivity Explorer

  • When you first log in, you’ll be guided through creating a “notebook” that contains one or more “localities”.
  • When you’re just starting out, it’s easiest to associate the notebook with a single locality.
  • Once you have an active notebook, the navigation bar allows access to many views. In general, the view settings hold across all related views and all notebooks.
  • You can have more than one locality in a notebook, but the map views work best if they’re geographically close — for example adjacent communities.
  • You can have any number of notebooks, but only one is active. There is a drop-down box in most views that allow you to change the “active” notebook.
  • The “Up” and “Down” buttons next to the Active notebook allow you to zoom out (or in) geographically — the main sequence is from Place to County to State, but the sequence differs depending on the locality you’re dealing with. For example, a Congressional District usually spans several counties, to zooming out would include all of the counties that the district touches.
  • The zoom level also persists across views, so if you move to a new view, the zoom level is the same.
  • You can print tables and maps, but the defaults don’t always guess correctly. You may need to scroll the map so that the areas of interest appear nicely in the printed version.


  • The Settings menu allows you to create, modify and delete notebook and localities.
  • The Explore menu provides access to background information about the datasets and the technologies
  • The Policies menu provides access to the Privacy and other policies.
