Version 6

Added marine and maritime data. 

All maps include bathymetry (depths), relevant features like boat ramps, slips, jetties etc, and navigational infomation (buoys, lights, wrecks etc). Don’t use it for actual navigation of your ship … Data will be straight from the gov’t computers so it should be as accurate as is possible, but I haven’t double checked it. 

Also adding 2018 seasonal road closures by giving affected tracks a pink co-line.
