Next Generation Map

We have recently been working on replacing the main CellMapper web based map.  This current map has its roots in code that was written around 2010, which, as you can image, makes it extremely difficult to add features into and fix bugs.
As a result, we've been experimenting with some new technologies in order to allow us to create a next generation map that is fast, mobile friendly, and has a good foundation upon to which we can add new features much more quickly than before.

You can see the new map at the following URL:
