Thank you for your questions and interest in the project

Shane, I'm going to write a blog post on this and try to get some of the
topics you raised.

Adam, the batteries are not being recharged currently however I am very
interested in solar going forward.

William, the map represents the approximate GPS location of the cell phone
tower that the GPRS modem is associated with . I get this location using a
built-in function of the GPRS modem and attach does latitude and longitude
as metadata to the trail counts. Going forward I may want to integrate a
GPS receiver on the device but for now this approximate location will help
me keep track of which sensor is which as I add more to the dashboard.
