This map covers Ohio and uses custom type styles developed on an Oregon 300 with shaded relief set to 'do not show'.
Transportation - Census TIGER (2010 Nov.- 2011 Feb) - enhanced
Hydrology - USGS NHD (2010 Sep)
Contours - 20 and 40 ft depending on terrain - created from USGS 1/3 arc sec (about 10m point spacing) NED (2011 Feb). USGS is now deriving the 1/3 arc sec data from State wide 1/9 arc sec LIDAR data
POI's - USGS GNIS (2011 Feb) - enhanced. NGS benchmarks
Boundaries: State & County from Census TIGER (2011-Feb). BLM surface management data (2011 May).

Version 2.0 Released May 30, 2011
There is an issue with the 64-bit installer used in the PC version of this mapset. If this is the first mapset you are installing on a Windows 7 64 bit PC, you will need to FIRST install a mapset which used a 32-bit installer, 'My trails ....' http://www.gpsfiledepot.com/maps/view/53 works and is small in size.
