How to calculate the real world coordinate data for a map pixel:
The lower left corner of the map coordinate is the origin (0,0) zero site.
The ratio of pixel to map coordinate is 0.05
Use GIMP open the map and move mouse to the site of the Home Station you
wanted, as shown in following. The map pixel coordinate for this site is
[229 ,182], which is shown on the bottom row, see following demo:
In following image, top red mark “608x512”shows the map size(W x H)
middle red mark shows the site of “Home Station”
lower red mark shows pixel coordinate for Home Station
