Topographic Map Symbols What is a Topographic Map? A map is a representation of the Earth, or part of it. The distinctive characteristic of a topographic map is that the shape of the Earth’s surface is shown by contour lines. 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. Contours make it possible to measure the height of mountains, depths of the ocean bottom, and steepness of slopes. A topographic map shows more than contours. The map includes symbols that represent such features as streets, buildings, streams, and vegetation. These symbols are constantly refined to better relate to the features they represent, improve the appearance or readability of the map, or reduce production cost. Consequently, within the same series, maps may have slightly different symbols for the same feature. Examples of symbols that have changed include built-up areas, roads, intermittent drainage, and some lettering styles. On one type of large-scale topographic map, called provisional, some symbols and lettering are handdrawn.

Reading Topographic Maps Interpreting the colored lines, areas, and other symbols is the first step in using topographic maps. Features are shown as points, lines, or areas, depending on their size and extent. For example, individual houses may be shown as small black squares. For larger buildings, the actual shapes are mapped. In densely built-up areas, most individual buildings are omitted and an area tint is shown. On some maps, post offices, churches, city halls, and other landmark buildings are shown within the tinted area. The first features usually noticed on a topographic map are the area features, such as vegetation (green), water (blue), and densely built-up areas (gray or red). Many features are shown by lines that may be straight, curved, solid, dashed, dotted, or in any combination. The colors of the lines usually indicate similar classes of information: topographic contours (brown); lakes, streams, irrigation ditches, and other hydrographic features (blue); land grids and important roads (red); and other roads and trails, railroads, boundaries, and other cultural features (black). At one time, purple was used as a revision color to show all feature changes. Currently, purple is not used in our revision program, but purple features are still present on many existing maps. Various point symbols are used to depict features such as buildings, campgrounds, springs, water tanks, mines, survey control points, and wells. Names of places and features are shown in a color corresponding to the type of feature. Many features are identified by labels, such as “Substation” or “Golf Course.” Topographic contours are shown in brown by lines of different widths. Each contour is a line of equal elevation; therefore, contours never cross. They show the general shape of the terrain. To help the user determine elevations, index contours are wider. Elevation values are printed in several places along these lines. The narrower intermediate and supplementary contours found between the index contours help to show more details of the land surface shape. Contours that are very close together represent steep slopes. Widely spaced contours or an absence of contours means that the ground slope is relatively level. The elevation difference between adjacent contour lines, called the contour interval, is selected to best show the general shape of the terrain. A map of a relatively flat area may have a contour interval of 10 feet or less. Maps in mountainous areas may have contour intervals of 100 feet or more. The contour interval is printed in the margin of each U.S. Geological Survey (USGS) map. Bathymetric contours are shown in blue or black, depending on their location. They show the shape and slope of the ocean bottom surface. The bathymetric contour interval may vary on each map and is explained in the map margin.

* USGS-USDA Forest Service Single-Edition Quadrangle maps only. In August 1993, the U.S. Geological Survey and the U.S. Department of Agriculture’s Forest Service signed an Interagency Agreement to begin a single-edition joint mapping program. This agreement established the coordination for producing and maintaining single-edition primary series topographic maps for quadrangles containing National Forest System lands. The joint mapping program eliminates duplication of effort by the agencies and results in a more frequent revision cycle for quadrangles containing National Forests. Maps are revised on the basis of jointly developed standards and contain normal features mapped by the USGS, as well as additional features required for efficient management of National Forest System lands. Singleedition maps look slightly different but meet the content, accuracy, and quality criteria of other USGS products.

** Provisional-Edition maps only. Provisional-edition maps were established to expedite completion of the remaining large-scale topographic quadrangles of the conterminous United States. They contain essentially the same level of information as the standard series maps. This series can be easily recognized by the title “Provisional Edition” in the lower right-hand corner.

Standards for 1:24,000- and 1:25,000-Scale Quadrangle Maps Part 6: Publication Symbols SUMMARY OF CHANGES Change Notice 7/01 An electronic complete revision of the Part 6 symbol book supersedes the hand-annotated printed version and is posted to the USGS NMP Standards web site. In addition to incorporating the previous pen-and-ink changes, the complete revision eliminates outdated symbols for airport outlines, rice fields, swamp clearing outlines, and black fence lines in land office States and Texas. It also includes changes that reflect the designations of patterns and fills currently in use. Change Notice 3/94 A change is made to indicate the addition of enhancement tint to Federally administered reservation boundaries. Change Notice 1/94 Changes are made to be consistent with the decision made during the October 19-21, 1992, Technical Exchange Meeting for the Hydrography and Transportation themes of the Standards for 1:24,000-Scale Digital Line Graph and Quadrangle Maps to include operational status only for the features AIRCRAFT FACILITY, RUNWAY, and ROAD (class 1 and 2 only). Change Notice 10/93 Changes are made to be consistent with STI 93-4-C, which provided new size criteria and symbolization for buildings shown on 1:24,000- and 1:25,000-scale quadrangles. Change Notice 8/93 The practice of pointing cave and mine shafts in the direction of the tunnel is changed to orient the shaft perpendicular to the contours. Change Notice 4/93 A change is made to indicate how to show former tidal gaging station sites in Florida. Change Notice 8/91 Changes are made to be consistent with STI 90-2-C, which redefined the revision categories and processes for the National Mapping Program products. Change Notice 7/91 The requirement to classify buildings is discontinued and the symbols for large buildings and tanks are changed from being patterned to solid black. Change Notice 11/84 These specifications were originally issued in 1958 as “Symbols for Standard Topographic Maps Published at the Scale 1:63,360 and Larger to be Scribed at 1:24,000-1:48,000�. The information subsequently was incorporated into the Topographic Instructions as Chapter 4A1. It was reissued in December 1981 with minor modifications to bring the symbols into conformance with current practices and with instructions to use the symbol specifications for all 1:24,000-scale standard edition maps prepared in conventional units. The 11/84 Change Notice specifies that the Part 6 symbol specifications are to be used only for photorevision or limited update maps when it is necessary to match the symbols on existing 1:24,000- and 1:25,000-scale quadrangle maps.
