... for the paper maps. But that's not sufficient info for a computer screen, because they work in dots, not inches. You also need to know the size of the image in dots, and the resolution at which it was scanned in dots per inch (DPI). Templot will tell you the image size in dots, and it's easy to guess the DPI with a bit of trial and error. To see the size in dots, select the map in the list and look below the list, like this: 2_230620_050000000.png The numbers are the width and height of the image, in dots. If you tell me those numbers, and your model scale, I will do the rest of the calculations for you, and suggest the most likely sizes for the map to try in Templot. cheers, Martin. posted: 23 Feb 2019 13:17 from: Hayfield Martin Its the OS five feet to the mile sheet VII.65 1893-1896 Holborn viaduct to the platforms Where can I find the tutorial please as I am struggling finding the old ...
