To have the symbols on my Flanaess as separate files so they can be easily used in various forms of software have been on my to-do list for a long time.
Here is a zip with volume 1 of the symbols on my Flanaess map:

Volume 1 contains all the base symbols. What is missing are the variants for Dwarven, Elven etc. They will be part of the next volume. Vol1 contains 119 different symbols in PNG (with transparent background) format, and SVG vector format.
SVG is vector so it is scale independent and usable in any size. Several symbols had issues that couldn't bee seen unless you scaled them up. I have tried to fix all the issues I saw, but if you see any I missed please tell me so I can fix them before putting them on my website.
