In 1879, the USGS began to <a href=\"https:\/\/pubs.usgs.gov\/circ\/1341\/\">map the Nation&#8217;s topography<\/a>. 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.<\/p>\n<p>The most current maps are available from <a href=\"https:\/\/nationalmap.gov\/index.html\">The National Map<\/a> and <a href=\"https:\/\/nationalmap.gov\/ustopo\/index.html\">US Topo<\/a> quadrangles. TopoView shows the many and varied older maps of each area, and so is useful for historical purposes\u2014for example, the names of some natural and cultural features have changed over time, and the &#8216;old&#8217; names can be found on these historical topographic maps.\u00a0<\/p>\n<p>TopoView was created by the\u00a0<a href=\"https:\/\/ngmdb.usgs.gov\/ngmdb\/ngmdb_home.html\" target=\"_blank\">National Geologic Map Database project<\/a>, in support of topographic mapping program managed by the <a href=\"https:\/\/www2.usgs.gov\/ngpo\/\">National Geospatial Program<\/a>.\u00a0 Geologic mapping and topographic mapping at the USGS have a long tradition together.<\/p>\n<div class=\"dnd-widget-wrapper context-full_width type-image\" readability=\"9\">\n<div class=\"dnd-atom-rendered\">\n<div class=\"field field-name-scald-thumbnail field-type-image field-label-hidden\">\n<div class=\"field-items\">\n<div class=\"field-item even\"><a href=\"https:\/\/www.usgs.gov\/media\/images\/topoview-philly-change-gif\"><img loading=\"lazy\" decoding=\"async\" class=\"img-responsive\" src=\"https:\/\/prd-wret.s3-us-west-2.amazonaws.com\/assets\/palladium\/production\/s3fs-public\/styles\/full_width\/public\/thumbnails\/image\/topoView%2C%20philly%20Change%20gif%20-%20July%202017.gif?itok=DrjfPAtt\" width=\"930\" height=\"405\" alt=\"\u200bComparing modern-day Philadelphia to the historical map of the area in 1891 gif\"\/><\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>\u200bComparing modern-day Philadelphia to the historical\u00a0map of the area in 1891.
