How can I measure travel distance on electronic maps?

Can you make a path in Photoshop? Select the Pen tool. Click where you want the path to begin and then click where you want it to end.

Next select the Type tool and click in the beginning of the path. Now you can write on the path. Wite a number (probably "0") and then press the tab key once. Write another number (probably "1"). Continue until you're satisfied. The numbers should now be evenly distributed along the path.

With the Pen tool you can add more anchor points on the path.

Then use the Direct selection tool to select and move those new anchor points.

Wouldn't that just place each number one tab's length away from the previous number's end, and not from the centre of the previous number? That is to say that once you start getting into double digits especially, it'll offset it quite badly.


I know that you can overlay an image onto google earth, and you can use that to measure distances. It's rendered entirely useless if your map is not of an entire world, of course. If you've got a world map, however, it should work fine. If you know Earth's dimensions and you know your own world's dimensions, it's a simple ratio change. You could even place the continent map onto Google Earth and find somewhere that is supposed to be roughly the same size as this place (unless you don't know. In which case, I'm sorry I'm being useless here. :s).

No, the tab's length are from the START of one set of numbers to the the START of the next set of mumbers. Just like a regular tab works in MS Word etc.
