Hello everyone. I have been lurking for awhile, but just joined the forum today. Here is my story, and I will follow it with my idea, which hopefully someone can help me with. I am an avid fisherman from Minnesota. I bass fish all summer, and ice fish all winter. I own the Eris, and am 200% pleased with it, and equally impressed with it's GPS functionality. I use it all of the time, and rely upon it's accuracy. Here is what I want to do. I want to take the lake maps (with depth charts) from the DNR website and overlay them onto the actual Google Maps images. So, when I access that app, it will show my location, but added would be the water depths that I overlaid onto the map. It seems easy enough to do, but I am too dumb to do it. Here is a rough sample of my intentions. Does anyone know someone who would be interested in teaching me how to do this, or someone who would help develop the app? Thank you all for any and all help.
