In 1999 I wrote the original AT Distance Calculator. I handed it off to Randy Rowell in 2010 and it is still up and running at
In 2011 I wanted to write a distance calculator for the Mason-Dixon Trail in PA, MD and DE. However, because of the way that their web server was configured, I needed to create a distance calculator that gave the results on the same page that the distance points were on. Ary Rodriguez, a developer where I worked as a system administrator, told me that he could code a web form that could do that. So Ary wrote the JavaScript code, I added the data and the HTML component and the rest was history. We should have been doing real work at the time so mea culpa.
Presented below are a number of trail distance calculators that I have written. If you find any bugs or would like an additional point added to any of these web apps, please use the
