What Is An Index Contour
What Is An Index Contour. Usually there are different contour intervals for the different maps. A contour interval on the survey is the vertical distance, or the difference in elevation between two contour lines of topographic maps.

A contour map legend usually identifies the contour interval on the map but sometimes available on only part of a map. Answer:index contours are bold or thicker lines that appear at every fifth contour line. A contour interval is a vertical distance or difference in elevation between contour lines.
On Most Maps, Each Fifth Contour Line, Shown As A Darker Line Or A Heavier, Is An Index Contour Or An Index Line.
A contour line accentuated by a heavier line weight to distinguish it from intermediate contour lines. This tells you the elevation above sea level. Index lines are the prominent contour lines represented with a round number contour interval.
For Example, In A Contour Map Of 0.25M Interval, Every Fifth Contour Line Will Be A Round Number (Like 1.00, 2.00, 3.00 Etc) And They Will Be Known As Index Contour Lines.

If the numbers associated with specific contour lines are increasing, t… Index contours are bold or thicker lines that appear at every fifth contour line. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line.
Contour Interval Is Used When A Big Space Is To Be Mapped To A Small Piece Of Paper.
Sharp contour points indicate pointed ridges. In a bigger map, index contour lines are much less to maintain the map easy to learn. A contour interval is a vertical distance or difference in elevation between contour lines.
Every 100 Ms Above Sea Level, The Contour Is A Darker, Thicker Brown And Is Also Labelled With The Elevation, While The Others Are Lighter, Thinner And Have No Label.
A contour map contains contour lines of a given geographical region.to maintain the contour map easy and understandable to read, not every. Index contours are bold or thicker lines that appear at every fifth contour line. An index contour line is shown after every five contour lines.
