Get your topographic maps here! The latest version of topoView includes both current and historical maps and is full of enhancements based on hundreds of your comments and suggestions. Let us know how we can continue to improve access to the USGS topographic map collection.

This interface was created by the National Geologic Map Database project (NGMDB), in support of the topographic mapping program, managed by the USGS National Geospatial Program (NGP). Geologic and topographic mapping have a long tradition together (see 1888 report). The NGMDB project is proud to assist the NGP in bringing these maps to the Web.

US Topo Series added to topoView 

 We've added the US Topo series to topoView, giving users access to over 3 million downloadable files from 2009 to the present day. 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 

 The latest version of topoView is full of enhancements based on hundreds of your comments and suggestions. We've added the ability to preview maps within the interface and give you tools to compare any historical map with maps of the present. Filters and searches work seamlessly with the map records table to get you the info you need with fewer clicks. Accessing the information you need is easier and quicker than ever. As always, your feedback is important to us so don't hesitate to let us know what you'd like to see in future releases!

Im new to sketchup and trying to design a property. Ive built a few structures to learn and still have a long way to go. But I am stuck on the actual plot of land I am designing. Its fairly sloped and I am wanting to start over with a base of building on the topography.

How are you going to generate the data? Are you engaging a surveyor? Generally data from open sources is not accurate enough to be used as a base for actual building operations. Surveyors can output their data in a form that can be utilized in SketchUp. The site data you get through the Geolocation function in SketchUp might be enough for rough sketches.

It seems manually creating it in sketchup based on 2d contour data may be the best or most accurate method. Though there is an app Moasure.com that I could walk the property and generate a file based on the data points I chose for accuracy. But we are talking over 4 acres @ 10-25% slopes.

Lots of good replies. I think I may try the cadmapper. Im still mostly in the pencil 2D stage of planning mostly with a little sketchup experience. Im having trouble visualizing the slope and necessary grading needs and a 3d model is going to help me wrap my head around it.

The U.S. Geological Survey (USGS) has been the primary Federal civilian mapping agency since it was founded in 1879. Some of the most well-known USGS maps are the 1:24,000-scale topographic maps, also called 7.5-minute quadrangles.

The Historical Topographic Map Collection (HTMC) is a digital repository of all scales and editions of USGS topographic maps. The HTMC contains thousands of scans of topographic maps originally published as paper documents between 1884 and 2006.

TNM Access Application Programming Interface (API) provides developers with programmatic access to historical topographic maps and US Topo as well as other geospatial data products of The National Map.

All topographic maps produced by the U.S. Geological Survey (USGS) are in the public domain and are not copyrighted except for the following three cases that apply only to US Topo maps (produced 2009-present): Most maps in the period 2010-2016 contain commercially licensed road data (see note below). Orthoimages in Alaska are commercially licensed. Orthoimages in Hawaii were commercially licensed...

Historically, USGS topographic maps were made using data from primary sources including direct field observations. Those maps were compiled, drawn, and edited by hand. By today's standards, those traditional methods are very expensive and time-consuming, and the USGS no longer has funding to make maps that way. A new USGS topographic map series was launched in 2009 and branded "US Topo." Though...

Bulk delivery is available for US Topo maps (produced 2009-present) and the Historical Topographic Map Collection (produced 1884-2006). Only current US Topo maps (not superseded maps) are available for bulk distribution (use topoView to download individual superseded maps). Bulk delivery options are currently only available for maps in GeoPDF file format. Options for bulk delivery: 1. Batch...

Like topographic maps, topographic map symbols have evolved over time. There is no single document that describes all of the symbols used on all USGS topographic maps since they were first created. Maps published 2013-present: US Topo maps have a symbol sheet attached to the map file (PDF format only). Open the PDF file in Adobe Acrobat and click on the paperclip icon.
