Pretty cool - thanks.

But I'm on GM 12 and have decided to sit out a few upgrades since it really does everything I need at this point.
BTW, if anyone is playing around with this, I made a couple small tweaks that I think produce better results. First, when I select all the features in the "Residential" layer, I am use primary BLUE as a color instead of RED like the tutorial. This seems to create a more accurate boundary between the forest and populated areas. Since red and green are complimentary colors, I *think* this was creating a gray zone between areas after blending in Photoshop and gray is closer to the black pallete color, therfore creating a gap.
The other difference is that I am up-sampling the raster export at 30 feet per pixel instead of 50 feet per pixel in the tutotial. This makes for less noticeable stair-steps as you zoom in on the finished map. At 50 feet/pixel the landcover starts to look pretty "jaggy" zooming in closer than .3 miles in Mapsource. At 30 feet/pixel the jaggies become noticeable when you hit the 500 foot zoom in Mapsource.
Further experimentation would be a good idea if you plan to use this technique, to see what you personally find acceptable. It also depends on other map features. In an area with lots of roads and/or contour lines the jaggies aren't so noticeable.
Also, in areas that are predominately forest you can end up with some huge and very complex green polygons. These are fine until you try to slice and dice them (such as as gridded export). If the polygons are too big and complex, GM messes them up when cropping sometimes. The only fix I have found for this is to work with smaller images to prevent the polygons from getting too large.
