Everything started during the Tollwood festival in summer 2012 in Munich. While I was looking at a signpost telling distances to different cities around the world, I wanted to have such a thing for my garden.
As a future geodesist I wanted to have the distances as accurate as possible, so I started to implement the calculations in MATLAB®.
I published my program on MATLAB® file exchange and after a few weeks I received the first requests and questions on it. In spring 2013 I decided to launch a web application under distanz-rechner.de. From now anybody can do an accurate distance calculation »on demand«. More details on the calculation can be found in » How it works. Later I started to translate the site into other languages based on my visitors' residence.
Some other features are in progress right now. I am going to publish them as soon as they are ready for use.
