View Full Version : Regional Map Scale

09-28-2009, 09:55 PM
I have a land-locked regional map (altitude false color with shadows) 250 by 444 km at 69.45m/pixel that I would like to change into a fantasy / steampunk regional map. Looking at printed maps what I want comes out to between 2.5 and 5 miles per inch. The map is going to be for online display, so I don't particularly care about the print-out, but I don't have a clue about how to scale information for online display.

In addition to standard terrain (hills, mountains, forests, lakes, marshes) the map will indicate cities, rivers, a variety of roads (including railroads, flagged and drained, graveled and ditched, and cattleways), cave entrances, and boundaries (counties, baronies, and the continental divide). It will probably include tourist landmarks, and hunting, fishing, hiking, and skiing areas, but I haven't completely made up my mind.

Any and all thoughts about what scale I should use would be appreciated.

I'm still looking for advice. I've looked at some online maps and, so far it looks like 64m/pixel is definitely too large and 128m/pixel is a trifle small. My original impulse was just to map to 100m/pixel. Could I have been right to start with?

Start with posting the map you want to use. Any advice people give will just be a shot in the dark without it.

I agree, it's a bit difficult to get a sense of scale without a visual (at least for me).

The map is a 40MB png. I'll put it on the web, but it will have to wait until I get to a computer with a better connection than my home one, which will take a while. As this is a map based on real-world information if you can tell what sort of things will help you I can probably dig up a comparison map.

Horizontally, this google map (http://maps.google.com/?ie=UTF8&ll=39.334297,-106.66626&spn=1.011198,1.299133&z=9) is roughly the area I'm looking at. Most of the "busyness" of the map is in or near the equivalent of Lake County Colorado (http://publicrecords.onlinesearches.com/maps/map-of-Lake-County-Colorado.htm) (and I'll be grabbing a lot of the county boundaries once I figure out what scale to use.

Finally got the map on the web. Warning: this is 40 mb, so I'm just going to provide the link.


What I'm currently looking at is downloading the USGS data and playing with various options in GIMP to see if I can get slope effects. Had I found this site first, that's what I would have gone for originally.

I'm still debating GIMP vs. AutoRealm.
