Right!

A new question which may have been answered before.

While working on a map of Sourthern Scandinavia, as part of a board game on the political situation in Denmark, during the period 900 AD to 1050 AD, I have come up with a problem which I'm sure, I'm not alone with; hex mapping.
This is of course only meant as a prototype of the final board, if it is ever to be published.
I have this large png-file map and I have to hex it into .5" hexes which has to be numbered. I plan to do this in either Adobe Illustrator or in Adobe Photoshop (both CS 3 versions).
After having layered the map and the hexes in two different layers, I plan to add trees, rivers, elevation aso. using coloration and different brushes i PS.
The hex grid (and the map) has to look like this (which is a picture of the GMT game "Under The Lily Banners").

How du I make this grid and how du I number each hex?

TIA.
