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.
