LG asked if I would try and help with the mini-map. Here's something I threw together this morning...
I start with a 1-pixel black round hard brush. Have the satellite map graphic on it’s own bottom layer. Zoom in a good bit and start tracing the borders. The “curviness” of the coastline is your call.
I’ve lowered the opacity of the base maps layer to about 35% - enough so I can see the image, but my new borders will stand out more.
I use a standard mouse. Try to move it your arm/wrist smoothly when tracing.
Also in Photoshop, you can move the canvas by holding the spacebar and moving your mouse. It helps when you’re zoomed in real close.
Next I’ll start a new layer for each of the bonus regions colors. You can either use a paint brush to color the regions, or the magic wand selection tool. I used the magic wand for this example. You can use the eye-dropper tool to match the big maps colors, or if you have a color pallet made, use that.
Now I have all my regions colored and on separate layers. I’m now going to ctrl-shift select all those layers so I end up with all the lands selected (First image below, before expanding by 1-pixel). Then I will go to Select > Modify > Expand by 1 pixel. It may be under a different drop-down menu, but you should find "expand" somewhere under the select menu. I will make a new layer and call it ALL LAND. I will fill this with a dark green. This layer is underneath the other color layers. I also add a very slight outer glow to this layer. This will give a well defined coast line and help the map stand out from the oceans.
That gives you your land. Next just play around with the font until you’re happy. I normally like crisp black text. I found it hard to position the text horizontally, so I tilted it all and liked how it looked.
