About SVGZ Graphic: Final USGS DRG Topographic Map Update ....
Back when I was in Boy Scouts, we often used 1:24k quadrangle topographic maps from the USGS. These maps from the pre computer age, manually drafted, they are no longer updated in favor of GIS data sets and the computer created National Map product. Some of the trails and landmarks not in the GNIS dataset never made it over to the new maps - especially on state land. And the National Map topographic maps are hardly the works of art that many the old topographic maps were.
