The Blue Horizon map is no longer active.  The BlueHorizon site used to provide a dynamic and interactive Google map of the planet, showing all participating Blue Horizon edge hosts.  That map is no longer active, but this page describes how it worked and provides screen shots.

When you first arrived at the map page you would have seen something like this:


The blue dots on the map each indicated a participating active host on Blue Horizon (and gray dots indicating inactive hosts).  The locations were provided with the accuracy specified by their owner when the host was registered on Blue Horizon.  For example, the host could offer live realtime GPS location data, or actual static location data, optionally automatically obfuscated within some radius by the Blue Horizon system, or simpkly estimated by their public IP address.

Visitors could could scroll and zoom the map and tap any of the blue dots to reveal which of the Blue Horizon insight applications were being run on that host, as shown in the image below:


Tapping on a dot would enlarge the blue dot and also reveal one or more concentric circle containing icons for each of the Horizon Insights the host was running.  In the case of the highlighted host above, it is participating in the Software Defined Radio (SDR) insight (the radio antenna tower icon on the top left) and the Network Speed insight (the wifi network icon on the top right).  Tapping any of the Horizon Insight dots would take you to a page associate with that Horizon Insight application, tailored specifically for the selected edge host.

The Blue Horizon map also supported airplane tracking, by receiving ADS-B broadcasts on the SDR receivers of participating Blue Horizon edge hosts.  Whenever "planes" was enabled (with the check box at the top left of the map) map visitors would be shown realtime aircraft information in an interactive map, as you can see in the screen shot below:


Each plane was rendered with with a shadow showing the spot it was directly above, and with its size corresponding to its altitude (higher altitude planes are closer to the viewer so they are rendered larger).  Selecting a plane would show the flight information previously observed for that plane.  The plane with the black trail above, shown at low altitude (small icon) above at the south end of San Francisco Bay, apparently came in from somewhere to the east.  You can see from its trail that it has recently turned right, presumably to make its approach to San Francisco International Airport (SFO) which is on the West side of the bay just South of the city.  You could watch these icons move around in real time as updated data was read from their open ADS-B broadcasts.
