  1. This map product series, named “US Topo,” is modeled on the now historical USGS 7.5-minute (1:24,000 scale) topographic map series produced and printed by the USGS from 1947 to 2006. US Topo maps have the same extent, scale, and general layout as the historical topographic maps. US Topo maps incorporate an orthorectifie

  2. The project was launched in late 2009, and the term “US Topo” refers specifically to quadrangle topographic maps published in 2009 and later. These maps are modeled on the familiar 7.5-minute quadrangle maps of the period 1947-1992, but are mass-produced from national GIS databases on a repeating cycle.

  3. The US Topo series is a latest generation of topographic maps modeled on the USGS historical 7.5-minute series (created from 1947-1992). Like the historical topographic mapping collection, we've added a variety of file formats previously unavailable for the US Topo series, including GeoTIFF and KMZ.

  4. USGS OnDemand Topo maps and USGS US Topo maps are built using similar datasets but can look different depending on what areas or options the user selects. OnDemand Topos--created using the topoBuilder application --offer customizations such as custom extents, a variety of scales, contour smoothing, and user-selected data layers.

    Topographic maps originally were produced to support a geological survey of the western United States (Powell, 1888). But they quickly became popular with many other disciplines and with the general public because of their usefulness for viewing and studying the Nation’s vast landscape (U.S. Geological Survey, 2010a, 2010b). Technological capabilit...

    The distinctive characteristic of a topographic map is that the shape of the Earth’s surface is shown by contour lines. Contours are imaginary lines that join points of equal elevation on the surface of the land above or below a reference surface, such as mean sea level. Contours make it possible to visualize the height of mountains, depths of the ...

    In most web mapping interfaces, there are a variety of ways to zoom/pan around the map. In topoView, panning is enabled by default. Simply click anywhere on the map, hold down the left mouse button and drag the mouse. For zooming into an area, we offer the magnifier tool, but instead you may find it easier to: 1. Hold the shift key and drag a box o...

    To find maps for a location, such as your house, or town, or larger area, use the location search bar. There, you can enter very specific information, such as your full street address (e.g., 12201 Sunrise Valley Drive, Reston, VA 20192) or latitude/longitude coordinate pair, or more general information (e.g., zip code, town name, or park name). Not...

    When you click on any of the colored map boxes, a map records table is populated along the right side of the interface and a marker appears on the point that was clicked. By default the active record is expanded and contains information like quadrangle name, map year, map edition, map scale, and a list of downloadable files associated with the reco...

    The information for a particular map can be accessed by simply clicking on the map record. When clicked, the map information window will expand revealing the basic metadata information, the map download options, a list of actions for that particular record (detailed later in this guide), and a preview image of the map (click the preview image to vi...

    A base map, commonly shown as a backdrop to give locational information such as cultural or physical features, is essential to help us locate ourselves on the ground. TopoView offers a variety of base maps which can be toggled in the upper left corner of the map window. Our default base map layer is powered by Mapbox using open data from OpenStreet...

    TopoView offers the topographic maps in a variety of downloadable file formats, in order to meet a range of user needs. The GeoTIFF, KMZ, and GeoPDF formats are georeferenced file formats. Georeferencing means that the internal coordinate system of a map can be related to a ground system of geographic coordinates. The relevant coordinate transforms...

    TopoView lets users preview any of the historical maps within the interfaceand provides tools to compare them to a modern base map. Overlaying historical maps on a modern base allows users to explore things like coastline change, urbanization, geographic name changes, and how people have altered the landscape over time. To preview the map record in...

    Metadata is the background information which describes the content, quality, condition, and other appropriate characteristics of the data. Paper maps contain metadata, primarily as part of the map legend. In this form, metadata is readily apparent and easily transferred between map producers and map users. When map data are in a digital form, metad...

  7. US Topo is the next generation of topographic maps from the U.S. Geological Survey (USGS). Arranged in the familiar 7.5-minute quadrangle format, digital US Topo maps are designed to look and feel (and perform) like the traditional paper topographic maps for which the USGS is so well known.
