Making a map symbol collection

[vidugavia]

I'm in the process of scanning, cleaning and vectorizing rather a lot of map symbols from Olaus Magnus map Carta Marina from 1539. I'm working in gimp and Inkscape.

I now wonder what kind of formats I should use in order to share my work with the world. What do you think? I've been thinking about making a photoshop brush. Any more suggestions?

Transparent .png files are always nice.

It would be nice to have a vector format as well, since you're going through the effort of vectorizing them. SVG is an open standard and I think most vector packages open them, and they happen to be native to Inkscape, so that seems perfect.

If you're vectorizing then I agree with Alan that you should go with an SVG library. I personally prefer PNGs with an alpha channel to preserve the transparency, but I know plenty of people who swear by GIF. If you're interested in eventually turning these into brushes, then a GIF is a good one to go with, as it'll save you the trouble of (re)layering any animated brushes at that point.
