Determine the area to be investigated. On a physical or digital map, establish the location of the area to be studied, noting the beginning and ending points. Acquire an elevation profile for this region. Consult a mapping tool such as Google Maps, MapQuest or Garmin for a topographical repr...
The background map is 2D, contains an area elevation marker, the second map is a seemingly 3D map containing a line marker. This 3D map is cut into pieces and placed on the base map. The cut 3D pieces are thrown into space and then placed in a place in the 2D map that corresponds...
This is to avoid the map being crowded with writing, making it harder to read. The key as to how to read a map is exactly that: a key. Also known as a legend, the key sits in the corner of the map for you to refer to and tells you what the different symbols mean so that ...
One of the advantages to using a topographical map is that it shows the three dimensional lay of the land. It does this by using contour lines. A contour line is a line that connects points of equal elevation. On the topo map they appear as the brown lines. ...
contour line. Contour intervals vary from map to map. Intervals set at 40-feet are common on 1:24,000 scale maps. But many maps, especially small scale maps, have 50-foot or 100-foot intervals. Index contours are the more prominent, bold colored lines with the elevation marked on them....
To be able to use these types of maps out in the wilderness, you need to learn how to read a topographic map. When reading a topographic map, you need to visualize a 3-dimensional view of what the symbols and contour lines on the map are showing. ...
Contour interval:The change in elevation from one contour line to the next is always the same within the same map. Many maps have either a 40- or 80-foot contour interval: An 80-foot interval simply means that each contour line is 80 vertical feet away from the next closest line. You ...
Topographic maps use contour lines to show the elevation of an area. These lines have rules: they cannot cross, and they form circles around hills...
Maps represent actual locations of areas, landforms, and water bodies. Learn how to read a map and find out the meaning and significance of...
Elevation Mountains and hills, or elevations, can also be represented on maps. This is usually done with contour lines. Contour lines are lines drawn on a map that join points of equal heights, generally in reference to sea level. The interval between the contour lines can vary, depending on...
