Maybe you've seen it? I was pointed to it a few weeks ago.
http://svg-edit.googlecode.com/svn/trun ... ditor.html
Tonight I used it to draw a quick map, saved to my desktop, loaded into svg2map and BAM!, done (with a few tweaks). Very handy. I don't know how long it will be there or how much development it will get but it's pretty cool. If it stays up we should add the link to wiki.arma under map making.
(also I'm looking to fill my new map with some good, aggressive, lower-rubber settings if you have any to donate - or I'll use my own.)
