The download was not terribly fast, however, I did get 105 kb p/sec download… not bad.
Clicking the “Download” link causes just that, I download a 5 MB file containing the USGS topo file. Clicking the “all maps for this location” option brings up a HUGE list of maps and data products for this region (shaded relief, topos, elevation maps, and other scientific data products). Geological Survey for decades, with nice additional features from our much-loved, but. These are the same topographic maps that were published by the U.S.

as a multi-page PDF that can be printed on letter size paper on any printer. The same topographic maps are also downloadable through other interfaces. National Geographic is allowing everyone to easily download any USGS 7.5 minute topo map in the continental U.S. Optionally, I can then order the data or even cooler… download the file directly (so why the heck would anyone actually go and pay to download this data from a datadepot or other “commercial” provider of these free data?). This is the primary search and download application for USGS topographic maps and base-layer GIS data. In my case I see a 7.5×7.5 quadrangle, a 30×60 sheet, and a 1×2 from a nearby area. Clicking on the ever-familiar Google map balloon icon invokes a pop-up window that displays all the available map products.
Once you’ve explored, you then have access to free data served up as GeoPDFs… read on for more about working with these GeoPDF data products… best of all this is all FREE!Īs a sample, I search using the term “Fort Collins, CO” – optionally, I can elect to view results that are either 7.5 or 15 minute (zoom in tighter for this one), or for 30 minute datasets. The USGS has a number of clever ways for users to search, navigate, purchase, and download maps and data… the Map Locator is the latest addition and it’s pretty darned sweet! Using a Google Maps UI, visitors search the map by entering a search string, zoom into an area of interest, or select a point on the map for relevant hits.
