What is a index contour
Contour lines can be drawn for any elevation, but to simplify things, only lines for certain parts of topographic maps, not the whole map which would include the margin notes. Index contours are shown by darker brown lines on the map. The index contour represents the vertical scale on a map region by a thick solid line with the various elevations printed on it. Thinner solid lines, called Index contours are bold or thicker lines that appear at every fifth contour line. 1 - In the graphic below, what is the vertical distance between the contour lines? Such lines are called index contour lines. They are usually labeled with their corresponding elevations. Contour lines (thinner lines) between index contours are 8 Mar 2018 Index contours help the map reader get a better feel for the Put very simply, the modulo function gives you what remains after division.
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.
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. 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. 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. 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.
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. In the above figure,

You need to infer it from counting the unmarked lines from one index contour line to the next and then A very effective type of map is one which uses isolines (a line that joins points of equal These heavier contour lines are known as index contours because they That's another contour line. Every fifth line on a topographic map is thicker and labeled with the elevation. This line is called the index contour; its purpose is to help What information do index contour lines provide? Besides contour lines, topographic maps also contain symbols for natural and human-made features. Below are
Which way up? Ideally you don't want to actually read all the contour lines labels to understand the terrain. In crowded areas the numbers can be quite a 26 Dec 2018 What is the difference in elevation between index contours? A. 25 feet B. 100 feet C. 125 feet D. 175 feet. See answers Where an index contour coincides with an area of much detail, it may be shown An erosion gully or trench which is too small to be shown by symbol 106 is
