Hi,
Here is a visual method that helps me keeping track when transferring a toppo map on a game map.
First you set coordinates in the topo map and then you choose a different scale for X and Y.
The reason of that is that the unit of measurement in the game map is a 6-side hex while in the topo map is a 4-side square. The best conversion (that i use) is for X-scale 1 kilometer=interval of 20 hexes: X axis_(0,0)-1km-(20,0)-1km-(40,0)...etc
For the Y-axis (I use) the conversion of y-scale 1 kilometer=interval of 25 hexes: Y axis_(0,0)- 1km-(0,25)-1km-(0,50)-1km-(0,75)...etc
For example the point (coordinates) 60,100 is 3km in the X axis and 4km in the Y axis. Of course the distance from (0,0) is (direct line) 5km (**root[3^2+4^2})
Anyway, here are the pictures of the visual aids for keeping track while designing on the editor map.
