My POIs: These are maps that contain points that are displayed on the 24K USGS maps. They are also transparent. I have also added other things. I found a file with the locations of 54,000 springs in MO and about 50,000 sink holes. I have included them. These maps cover, IL, MO, CO, IN, TN, DC, Iowa, KY, and OH.

These are transparent maps that show up on top of City Navigator which you still use for route calculation. They have topo lines and hydrology (streams, rivers, lakes, etc). The topo lines are from the USGS and they are more accurate than what is on the 24K USGS maps. I generally use a 10 foot contour interval. The hydrology is high resolution (equal to or better than the 24K USGS). Some places do not have the high resolution data). I have also done lots of corrections to the hydrology by looking at ExpertGPS, Google Earth, and field checks. What it looks like in the GPS is City Navigator with topolines and much better hydrology. This is great for caching as many times it helps you figure out how to get to a cache as you can see the terrain and where the water is. That makes it easier to figure out how to get to a cache as a straight line is not always the best way.

This set has three maps. One for the Mark Twain Lake (MOGA), Marquette State Park, and Cahokia Mounds State Historic Site. These are maps you can use if you don’t have City Navigator. These are non-transparent maps that have roads, trails, topo lines, POIs, and water. In MapSource you can also use them to see everything at once.
