UR - http://www.ngs.noaa.gov/NGSDataExplorer/ ER - TY - Generic T1 - Scanned "newer" 1:25K topographic maps (from MassGIS) Y1 - KW - #MapsDataPublications KW - #Topo KW - 1:25000 KW - 7.5 KW - historic KW - quadrangles KW - topographic KW - topographic maps KW - topography AB - MassGIS scanned the USGS topographic quadrangles to create a digital database that can provide images of the paper maps. These images can be used as a backdrop for plotting vector data and for interpretation and analysis. MassGIS scanned the 15-minute series (vintage 1982-1990) where these maps were available; the 7.5-minute maps (1967-1979) were used elsewhere. Note that the elevation labels for the contours on the maps may be in meters or feet, depending on the vintage of the original paper map that MassGIS scanned. Contour labels on maps from 1982 and later are in meters. Labels on maps from 1967 through 1979 are in feet. See the Index Map for details. Most paper maps are at 1:25,000 scale; some older 7.5-minute quads were produced at 1:24,000 scale.

TopoView highlights one of the USGS's most important and useful products, the topographic map. In 1879, the USGS began to map the Nation's topography. This mapping was done at different levels of detail, in order to support various land use and other purposes. As the years passed, the USGS produced new map versions of each area. The most current maps are available from The National Map. TopoView shows the many and varied older maps of each area, and so is useful for historical purposes—for example, the names of some natural and cultural features have changed over time, and the 'old' names can be found on these historical topographic maps.
