Historical topographic maps are useful in determining how topogrophy and property development has changed over time, and they indicate possible risks or concerns. A topo map is a two 2 dimensional representation of our three 3 dimensional world. Both horizontal and vertical data can be recorded. 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.

A contour line displays the peaks and the valleys of the land. It makes it possible to measure the height of mountains and the steepness of slopes. The USGS Topo Maps in mountainous areas may have contour intervals of feet or more but a map of a relatively flat area may have a contour interval of 10 feet or less. The smaller the cumulative drop, the more detailed the survey becomes.

The topo maps displayed in our viewer are collarless but we provide a link to view the original map, circled below:. The years shown for the topos may represent reprints of the original. Therefore, the collars may be useful for identifying reprints and other details.

More than contours are shown on a topographic map. The maps depict the natural features as well as the manmade attributes of the land. The natural features include the mountains and hills, rivers and streams, and type of vegetation. Manmade structures depicted on a topo map may include railway lines, buildings, utilities, houses, cities, schools, roads and highways.

Thousands of symbols that represent the many features have been created and changed over the years on USGS Topographic Maps. To decipher what the symbols mean visit our Topographic Key Map. The first maps were created at scales offor 1-degree andfor minute areas. Bymost of the maps were minute areas and produced at a scale ofThe features shown on the early maps included civil divisions of state, county, township, and cities or villages; manmade structures including acequia, bridges, canals, dams, ferries, fords, railroads, trails, tunnels, wagon roads, and trails; miscellaneous features of forest, sand and sand dunes; and the determination and mapping of the relative elevation of land with contours and flood plain representations.

The early maps were made from the field sketches using a three color lithographic printing process based on copper plates. The civil divisions and manmade structures were done in black, bodies of water in blue and contours, depressions and miscellaneous features in brown. Vintage copper engravings of the greater St. Beginning in the s, the USGS began experimenting with photogrammetry as way to replace the time requirements of field sketching.

By using a pair of stereo photographs in a stereoplotter by doubly reflecting the overlap area, elevations could be determined. This has been the primary method to plot contour lines on topographic maps since the s. Afterthe USGS used pen and ink drawings that were photographed to film separations, eliminating the need for copper plates. After a few years the pen and ink process was replaced by use of engravers and scribecoat.

Demand for more detail on topographic maps resulted in thescale 7. With the larger scale, the USGS included almost features separated into color groups for the five color plates to be used in the film-based reproduction process.Buy digital format on media: Online Local center or by phone.
