standard line and background designations of terrain objects used on topographic maps. A legend is a list that describes the symbols used on a map. It is impossible to label every single feature in words on a map, therefore we use map symbols. Symbols are used to represent geographic phenomena, which exist in, and are represented by, a variety of spatial forms. Symbols are one of four types—marker, line, fill, or text—depending on the type geometry they draw. 3 minute read. See Also: Map Skills, Compasses & Directions, Maps, Overviews & Huge Sites, Geography Lesson Plan Index. HOME . Map symbols are intended to provide designations of common outline and color for similar groups of objects; there are no major differences among the basic symbols used on topographic maps in various countries. Map symbols simultaneously serve several purposes: Description & Examples: Maps show features in a plan view as birds see it from above. Usually found at the map's top or bottom corner, this string of numbers and letters is a timestamp. Map symbols generally convey the appearance (shape and dimensions), location, and certain qualitative and quantitative characteristics of the objects, contours, and relief elements shown on maps. B. The area occupied by the scale symbol may be delimited and colored, as in the case of forests, bodies of water, or blocks in population centers; it may be hachured, for the depiction of swamps, solonchaks, and floodwaters; or it may be filled in with graphic signs, usually in checkerboard fashion, as in the case of grass and semishrub vegetation or clayey and hum-mocky surfaces.
), unit reference numbers, IP addresses and Map symbols represent the physical features of land and help the map's reader gain an acute awareness of his surroundings. City Symbols. Sandbars in rivers, as well as orchards and vineyards, may be emphasized by a combination of these methods, Nonscale symbols are used to show objects that are not expressed in the scale of the map (primarily local objects); such objects are shown in a top or side view.The point on a map symbol that indicates the actual position of the real object depends on the type of object.

Represented by different colors and shapes, map symbols are used to indicate certain terrain features or important locations in a specified area. Waterfalls are also shown and mark small waterways with a notch, while large rivers are marked with ripples.Is the Coronavirus Crisis Increasing America's Drug Overdoses?Fact Check: What Power Does the President Really Have Over State Governors?Festival of Sacrifice: The Past and Present of the Islamic Holiday of Eid al-AdhaHow Worried Should We Be About the Saharan Dust Cloud’s Arrival?Has the Time Come to Abolish the Electoral College?Is the Coronavirus Crisis Increasing America's Drug Overdoses?Fact Check: What Power Does the President Really Have Over State Governors?Festival of Sacrifice: The Past and Present of the Islamic Holiday of Eid al-AdhaHow Worried Should We Be About the Saharan Dust Cloud’s Arrival?Conventional Signs and Symbols Used in Topographic MapsConventional Signs and Symbols Used in Topographic Maps These symbols are commonly used to describe different features mapped. They are conventionally divided into area, non-scale, line, and explanatory symbols.Scale map symbols are used to reproduce topographic features whose shape and dimensions in plan can be expressed within the scale of a particular map. Intro to Map Symbols. Sound and geographic visualization. One of the first coded pieces of data you might notice on a weather map is a 4-digit number followed by the letters "Z" or "UTC." For example, a point is used to fix the place where absolute relief measurements or relative differences, such as the height of a kurgan or cliff, have been determined. For example, Moscow Oblast is shown as Standardized typefaces for captions on topographic maps make it possible to give important information in addition to that provided by symbols. Different kinds of symbols are used to portray different spatial forms.The number of spatial dimensions needed to represent a phenomenon determine a choice of The dimensionality of a map symbol representing a feature may or may not be the same as the dimensionality of the feature in the real world; discrepancies are the result of Many map symbols visualize not just the location and shape of a geographic phenomenon, but also one or more of its properties or attributes. A map may have different symbols for cities, rivers, lakes, roads, railroad tracks, and so on. If some such object can only be reproduced on the map with an exaggerated width, its position in plan is fixed by the axis of the symbol. Make a map activity card. NOAA JetStream School for Weather. The typefaces for rivers indicate size and navigability. These symbols come from the Unified Modeling Language or UML, which is an international standard for drawing process maps. Symbols graphically describe, categorize, or rank geographic features, labels, and annotation in a map to locate and show qualitative and quantitative relationships. B., & Reeves, C. (1992).
