This was my entry in the Aug-Sept Light Challenge: http://www.cartographersguild.com/showthread.php?11588-August-September-Entry-Portolan-Chart

I created it using Inkscape and Ruby. All the textures were generated as SVG Filter effects.

My primary inspiration was this chart: http://en.wikipedia.org/wiki/File:Mediterranean_chart_fourteenth_century2.jpg

There isn't much story to it. I've decided to call the inhabitants of the central island 'High Elves'. Those to the north are 'Dark Elves', and the southeast island has 'Dwarves'. I slapped together simple naming languages for them and wrote a generator (one of the things I used Ruby for).

I've also made a wallpaper version: http://hai-etlik.deviantart.com/art/Portolan-Chart-Wallpaper-179320559

Looks good so far. Cool font! I would personally remove the lines from the land masses. Most ancient maps I know don't display those lines on the land. But I might be wrong. :)

Most portolans I've seen, including my model, extend the rhumb lines into the land. And it's actually a renaissance style of map not ancient.

The typeface is Orotund: http://www.fontsquirrel.com/fonts/Orotund

I meant to ask before - what are the bottom left and upper right boxes?

Scale bars, though I've no idea of the unit. Presumably the Elves just assume that anyone who should have one of their maps knows what the preferred Elven unit of distance is. I modelled them fairly closely on the one in the source map.

That is a really fantastic map! I love how you made the ink look old and worn, if you don't mind me asking, how did you do it?

The ink effect is an SVG filter effect I put together. The core of it is simply a turbulence filter and an IN composition with the source image, then a normal composition with a faded and blurred copy of the source image. Besides that it incorporates displacement mapping, colour matrices (To tweak the alpha channel at various stages), and ends by doing a multiply blend with the background.
