Wow!
Thanks to everyone who worked on this. What a great resource. I wanted to add topo maps to my 60CSx but didn't like the fact that I had to toggle between CN and Topo maps. These transparent maps solved the problem. I built a couple yesterday following your instructions, and they came out great.
I have not tried adding water yet, cause I wasn't sure how to match the sizes of the maps. can you describe what you mean by trimming the water map? Do I do this after the download?
Thanks again!
