What distinguishes topographic maps from other types of maps?
Like General Reference Maps, Topographic Maps are a summary of the landscape and show important physical (natural and man-made) features in an area. The primary difference is that they show elevation in detail. Characteristics of topographic maps include: they show elevation using contour lines.
What are the four main uses of topographic maps?
Topographic maps have many multiple uses in the present day: any type of geographic planning or large-scale architecture; earth sciences and many other geographic disciplines; mining and other earth-based endeavours; civil engineering and recreational uses such as hiking and orienteering.
What kind of maps does the military use?
A military city map is a topographic map (usually at 1:12,550 scale, sometimes up to 1:5,000), showing the details of a city. It delineates streets and shows street names, important buildings, and other elements of the urban landscape important to navigation and military operations in urban terrain.
How are topographic maps measured?
In the late 19th century, surveyors created topographic maps in the field. They measured a series of points in the field, using tape and compass traverses with elevations determined with an aneroid barometer and used in a process known as field sketching to draw a terrain representation using contours.
What are some examples of topographic maps?
Examples include mountains, hills, valleys, lakes, oceans, rivers, cities, dams, and roads. Elevation - The elevation, or height, of mountains and other objects is recorded as part of topography. It is usually recorded in reference to sea level (the surface of the ocean).
What are the two types of topographic maps?
Contour maps use contour lines to indicate height and maybe, more importantly, changes in elevation across the terrain. A relief map is a type of topographic map that doesn't use contour lines. Elevation data is continuous data.
Why do we use topographic maps?
Topographic maps are used to understand the shape of the land, whether a slope will fail, how glaciers are changing, and geologic history, among many other things.
How do you make a topographic map?
Draw a horizontal line on the graph paper that is the length of your profile line. Draw vertical lines above your starting and ending points. Label the y-axis (vertical lines) with elevations making sure that your scale goes from highest to lowest on your cross-section (see step 3).
What is the importance of topographic maps?
Topographic maps are an important tool because they can represent the three-dimensional landscape in two dimensions. A person who can read a topo map can find out the location of peaks, valleys, ridges and saddles, among other land features.
What are the 5 colors on a map?
- RED -Overprinted on primary and secondary roads to highlight them. ...
- BLACK -Manmade or cultural features.
- BLUE -Water-related features.
- BROWN -Contour lines and elevation numbers.
- GREEN -Vegetation features.
- WHITE -Sparse or no vegetation. ...
- PURPLE -Denotes revisions that have been made to a map using aerial photos.
What does 1 50000 mean on a map?
The scale on a map is the ratio between real life sizes and how many times it has been shrunk to fit it on the map. On a 1:50,000 scale map, 1 cm on the map represents 50,000 cm on the ground (= 500 m or 0.5 km).
What compass do Army Rangers use?
For the ultimate in precision sighting, look no further than our ranger cl compass. Known to perform under the most demanding conditions, it has features like a split-sighting mirror, so you get superior accuracy when navigating on distant landmarks.
