What is a index contour

Index contours are shown by darker brown lines on the map. These are the contour lines that are usually labeled. The example at right is a section of a topographic map. The brown lines are the contour lines. The thin lines are the normal contours, the thick brown lines are the index contours. The index contours are a darker or wider brown line in comparison to the regular contour lines. You'll see the elevations marked on the index contour lines only. To determine elevations, pay attention to the amount of space in between lines. If the contours are close together, you're looking at a steep slope.

Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. This tells you the elevation above sea level. This tells you the elevation above sea level. Index contours are shown by darker brown lines on the map. These are the contour lines that are usually labeled. The example at right is a section of a topographic map. The brown lines are the contour lines. The thin lines are the normal contours, the thick brown lines are the index contours. This reference line is an index contour. As noted earlier, an index contour is one that is a bolder, darker contour line and has a value written on the line ever so often. First, find the value of the index contour addressed in the question and then follow the line until you see a number associated with the line. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. A contour interval is the vertical distance in meters or feet between contour lines on a topographical map. These show the general rise and fall of the land and help identify and define terrain features such as hills and valleys. Index contours give specific elevation data for a particular line.

Index contours are shown as slightly darker lines to make them more  An index contour is one of the ways that vertical dimension, or vertical scale, is demonstrated on a topographical map. The index contour represents the vertical scale on a map region by a thick solid line with the various elevations printed on it.

Put simply, a contour line is a line which joins points of equal elevation above sea level; they have an This is the index for the IMW maps which cover Australia.

An index contour is one of the ways that vertical dimension, or vertical scale, is demonstrated on a topographical map. The index contour represents the vertical scale on a map region by a thick solid line with the various elevations printed on it. Definition of index contour. A contour line shown on a map in a distinctive manner for ease of identification, being printed more heavily than other contour lines and generally labeled with a value (such as figure of elevation) along its course. index contour line A contour line accentuated by a heavier line weight to distinguish it from intermediate contour lines. Index contours are usually shown as every fifth contour with their assigned values, to facilitate reading elevations.

Index contours are shown by darker brown lines on the map. These are the contour lines that are usually labeled. The example at right is a section of a topographic map. The brown lines are the contour lines. The thin lines are the normal contours, the thick brown lines are the index contours.

Index contours help the map reader get a better feel for the topography of an area. Symbolising index contours is easy to do with a little bit of preparation. In an earlier post we looked at creating elevation contours: This time we’ll look at how we can better display our contours by symbolising some index contours. On a topographic map, an index contour is a contour which is usually thicker and bolder with its elevation value written on it. Using this index contour and the contour intervals, we can estimate the values of other contour lines on the map. A contour map consists of contour lines of a given geographical region. To keep the contour map simple and easy to read, not every contour line is marked with its elevation reading. These marked or labeled lines are known or termed as Index Contour Lines.
