Available Online USGS Map: How To Use The USGS National

USGS is a government survey agency which surveys and maps the geological formation of the country. By the use of various grids, signs, symbols and colors one can learn the topography of the earth, where the earthquake faults are and many other things. There are 56,000 usgs map reproductions which are available to view.


Thanks to modern technology, anyone who has a computer has access to these maps. By going to the USGS store on the Web, it is very simple to copy any map and print it out on a home printer. The beauty of this arrangement is that a whole map or a specific section can be selected and printed. Pre-printed maps are also available for purchase on this site.

These maps give a person access to learn everything and anything about the country. From mountains to underground water, all the information is available at the click of a mouse. This has been found to be an excellent source of information for many people, including scientific and history buffs. Students, especially, have found this site an excellent source of information for their studies.

Hikers, backpackers, campers, fishermen and many others have been able to use these maps to plan their trips with ease. They can find which roads to travel, which areas have deep canyons, where the best fishing is and many other things. This makes an excursion much easier to map out and avoid any obstacles along the way.

Using the map database is very easy and, once on site, very simple directions lead the viewer on the way. In addition to free maps, there are free analytical tools available. The vivid colors clearly indicate various things, such as blue for water, green for vegetation, red for roads and so forth. Symbols are explained and appear clearly on the map. Everything, including railroads and buildings are indicated, depending on which map one is looking at.

It is possible to concentrate on one particular area with one particular interest. For example, if one were interested in earthquake faults in California it would simply be a matter of looking up ‘earthquake maps’. These maps will not only show where the earthquakes are most likely to appear but will provide history of past and possible future quakes as well.

States and the government have found this site particularly important regarding building codes. There is a National Code as well as state codes regarding where buildings can be built without danger of, for instance, earthquakes. This has proved invaluable, in protecting property as well as human life. The database also makes it simple for a prospective project developer to determine where it is feasible to build.

This Government Survey Agency, as well as members of the NEHRP (National Earthquake Hazards Reduction Program and other agencies, have done wonders in presenting a clear and concise picture of the land that lies above and below the countryside. Having these watchdogs on the scene has enabled many mishaps to be avoided by their monitoring and predicting future occurrences.
