Answer 1

There is a product that is similar. Logitech makes a pen that will store the written information digitally. Then you can connect it to your computer and upload whatever you wrote or drew. The problem is it needs a special kind of paper to write on so it has a reference to where it is on the paper.

The easiest way to find the distance from one point to another on a map is to use an online map like google maps.
