Thread: Scaling Maps in Photoshop

Um, I really suck at math (more so at 2am) but I think if you have a 1 to 1 and you want 1 to 1/8, you need to make it 8 times bigger? I took the liberty of downloading your image and doing the following: bigger the circled bit by 400%; gaussian blur 1.5 to smooth it a bit; and unsharp mask set to 100 1.0 0 to bring back some of the crispyness. Mind you, even re-sizing this much it looses a lot in quality. But I don't know of any other way to do it. Maybe someone with more knowledge can enlighten us.

Basically yes - x8.

Section 11 onwards. Maybe you can try some of the newer fancier resampling options out there now. Resampling upwards is always a limited exercise so for this reason always make any maps at as high a res as you can stand if you think your going to want to do that in the future.

The way I approach things is I go ahead and do the resize, then I merely use that image as a template for the new map. Here's an example of my workflow:

Of course, I was drilling in much deeper than only 8:1. It's more like 25:1, I think.

bump your dpi up to 2400
