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. New functionality driven by your feedback

Topographic Mapping and the USGS. A longstanding goal of the USGS has been to provide complete, large-scale topographic map coverage of the United States. The result is a series of more than 54,000 maps that cover in detail the entire area of the 48 contiguous States and Hawaii. Produced at a scale of 1:24,000 (some metric maps are produced at ...

There are three ways to get full-scale plots of USGS topographic quadrangle maps, including Historical Topographic maps (produced 1884-2006), US Topo maps (produced 2009-present) or customized OnDemand Topos. Order a paper map from the USGS Store. Use the Store’s Map Locator to find the desired map.* Download a free map file and send it to a local printing business.

1. The Historical Topographic Map Collection (HTMC) is the set of scanned images of USGS topographic quadrangle maps originally published as paper documents in the period 1884-2006. Visit Historical Topographic Maps - Preserving the Past for more information. 2. US Topo is the current USGS topographic map series for the Nation.

In modern mapping, a topographic map or topographic sheet is a type of map characterized by large- scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods. Traditional definitions require a topographic map to show both ...

A large-scale map has a smaller ratio (1:10,000 or 1:25,000) and would have more details such as streets and building footprints. Whereas a small- scale map has a larger ratio (1:500,000 or 1:1,000,000) and illustrates an entire state , province , or country with just the larger cities or towns and major highways .

Therefore a RF scale of 1:1,200 is the same scale as a verbal scale of 1″ = 100′. USGS topographic maps typically have both bar scales and representative fractions (RF). ... For example, a large scale map could have a RF scale of 1 : 1,000. Large scale maps are typically used to show neighborhoods, a localize area, small towns, etc.

Figure 2.9 Map Scale from a United States Geological Survey (USGS) Topographic Map. ... For instance, a map with an RF of 1:1,000 is considered a large-scale map when compared to a map with an RF of 1:1,000,000 (i.e., 1:1,000 > 1:1,000,000). Furthermore, while the large-scale map shows more detail and less area, the small-scale map shows more ...
