Contour lines
- The curved lines on a map are called contour lines. They are thin, curved lines that appear to wrap around certain areas on the map. Contour lines connect points of equal elevation, allowing us to visualize the shape and steepness of the terrain.

Aug 18, 2022 · Topographic Contours. Many maps of land areas have series of curved lines, called contours, that represent the topography of the area. Such a map is called a topographic map. A contour is a horizontal curve that’s the locus of all points on the map with the same elevation (Figure 3-35).
Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation. If you walk along a contour line you will not go uphill or downhill. Mathematically, a contour line is a curve in two dimensions on which the value of a function f(x, y) is a constant.
Feb 17, 2024 · Contour intervals on a topographic map show the elevation of the land, usually expressed in feet or meters. These contours are usually represented by a series of curved lines, called 'contour lines', that connect areas of similar elevation.
The fi rst features usually noticed on a topographic map are the area features, such as vegetation (green), water (blue), and densely built-up areas (gray or red). Many features are shown by lines that may be straight, curved, solid, dashed, dotted, or in any combination. The colors of the lines
Jul 4, 2023 · Contour lines are curved lines on a map that connect points of equal elevation. They help us visualize the shape of the land, including mountains, valleys, and hills. By reading these lines, you can determine the steepness of slopes and identify potential obstacles or landmarks.
Sep 24, 2014 · Particularly what is the difference between a straight line, which is a Rhumb line on Google Maps, and a curved line. There is a common misconception that if you were to walk in one direction without wavering and then drew a line of all the places you stopped it would appear as a curve on a map.
