Google Maps: A Tool For Mapping And Surveyingīy displaying contour lines for every location on the planet, Google Maps is an excellent tool for mapping and surveying. The elevation of a map is usually shown by its location at every fifth contour line, which aids in the identification of elevation changes. In essence, topographic maps represent the three- dimensional landscape of Earth within a two-dimensional space.Ī map’s index contour line is a bold or thicker line that identifies the elevation of various points. A topographic map uses a combination of colors, shading, and contour lines to reflect changes in elevation and terrain. What Maps Show Contour Lines?Ī topographic map is defined as one with contour lines on it. These maps are distinguished by contour lines that show changes in elevation and can be used to see features as small as a house or as large as the Himalayas. The higher the elevation, the higher the color. Topographic maps, which depict elevations in shades of blue, show the shape of the Earth’s surface. These lines have more spacing than the Intermediate lines and are used to measure changes in elevation. This section shows elevation changes using Supplementary lines. They are distinguished by spacing farther apart than the Index lines and thus show more complex slopes. The intermediate lines are used to distinguish hills and elevations that are not precisely located. Using these points, steep slopes can be seen by connecting points of equal elevation. The index line is the most fundamental type of contour line. Finally, you can often find contour maps in hiking and camping guidebooks. Another way is to purchase a contour map from a store that sells them. One way is to go online and search for them on a website such as Google Maps.
