Thanks.
One issue for large water bodies like Mark Twain Lake, Mississippi River,
etc is when you add them to the topo maps since they are transparent
overlays, they cover roads crossing the lake and river. So what I do is if
the water body is in City Navigator, I will not add it to the topo map.
Mark Twain Lake is like that. So the topo map does not have the lake. Many
times the hydrology from USGS is better quality than what is in City
Navagator and will not match up with the topolines as well as the USGS data.
Also remember lakes and rivers rise and drop. So you are never sure where
the actual water ends.
Also remember I have these topo maps for most of the STL area. So they
have much more use than just MOGA.
Like I said, if anyone wants them let me know and I will train you on how to
install them. Its real simple once they are installed.
If anyone has track files of the trails in the MOGA area, I can add them to
a trail map.
