Use a blue color pencil to draw a curvy stream or small pond.

. For example the 500-foot contour line for a topographic map connects points that have an elevation of 500 feet. Essentially topographic maps represent the three-dimensional landscape of Earth within the two-dimensional space of a map. Topographic maps use a combination of colors shading and contour lines to represent changes in elevation and terrain shape.

Open an existing map the more recent the better. In this case a line of equal elevation. A map with contour lines on it is called a topographic map.

Every map has a. A topographic map is printed on a flat piece of paper yet it provides a picture of the terrain and man-made features through the use of contour lines colors and symbols. Depression contours - getting into and out of a hole Take a look at this volcano with a crater at the top that rises up above a flat plain.

Save it as new in a different folder under the same root directory. The part of the map illustrating the map area. Topographic maps use contour lines to show different elevations on a map.

Geological maps are maps that illustrate the rock types rock ages and other geological features of the mapped area. Topographic maps are maps that illustrate the topography vertical shape such as hills of the mapped region. Start with a sheet of drawing paper I use 9x12 construction paper the size will dictate the size of the final model.

Map area or data frame. Contour lines represent the shape and elevation of the land such as ridges. Mapping is a crucial part of Earth science.

Contour lines are used to determine elevations and are lines on a map that are produced from connecting points of equal elevation elevation refers to height in feet or meters above sea level. Create a Map From an Existing Map. If you walk along a contour line you will not go uphill.

Draw a 12 border on each of the edges. A map is a plan view representation of an area on Earths surfaceTopographic maps are maps that illustrate the topography of the mapped regionGeological maps are maps that illustrate the rock types rock ages and other geological features of the mapped area. Pick a spot for your cabin.

For example a topographic map with a 20-foot contour interval would have a curve for 500 feet another for 520 feet and so on. Each contour map has a contour interval that governs the spacing of the contour lines. The topographic map of Painted Canyon in the worksheet and near the end of these instructions shows the elevation of the land surface and will be used to locate your samples.

Topographic maps also have a vertical scale to allow the determination of a point in three dimensional space. Ive marked the elevations of the highest point on the volcano on the rim between its outer slopes and the crater the lowest point in the crater note that its not in the center of the crater and a. Goals for This Week Understand what a topographic map shows eg contours and be able to recognize features hills ridges valleys etc on a topographic map.

Fetch the layers for your map see. A contour line is a type of isoline. Its time to improve our initial cabin map and make it a topographic map.

Topographic maps represent the locations of geographical features such as hills and valleys.
