What is meant by contour interval?
A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing.
What is contour and its characteristics?
Contours show distinct characteristic features of the terrain as follows: i) All points on a contour line are of the same elevation. ii) No two contour lines can meet or cross each other except in the rare case of an overhanging vertical cliff or wall. iii) Closely spaced contour lines indicate steep slope.
Which best describes a contour line drawing?
Contour drawing is the place where most beginners start, following the visible edges of a shape. The contour describes the outermost edges of a form, as well as dramatic changes of plane within the form. Put simply, a contour line drawing is an “outline drawing,” that uses no shading.
What is pure contour drawing?
Pure contour line drawing is the simplest form of linear expression. The line describes visible edges of an object. If the subject is carefully chosen and oriented, a pure contour drawing can have strength, clarity, and simplicity. Draw only clearly defined edges, resisting the temptation to color in shadows.
What is contouring and contour 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.
What are the uses of contouring?
Uses of the Contour Lines
- To estimate the water storage capacity, back water limit and max .
- Volume of the proposed excavation wok,
- To decide whether certain location is visible from another location,
- To decide exact line of railway or road way haing safe slope,
- To determine the ground water level from contours of ground water.
What is the difference between a contour line and an outline?
Lines that describe a shape of a figure or an object and also include interior detail. These lines can vary in thickness. an outline is the line made by the edges of an object. Contour lines describe the shape of an object, and include interior detail.
What is the outline of a shape called?
The visual outline is the line or set of lines that define a shape or figure. They are the outlines that configure the shapes. The length or measure of a contour is called perimeter , used especially in mathematics and technical drawing. The stroke makes the contour line or outline.
What is line quality art?
Line quality is also called line weight and simply put, refers to the thickness or thinness of the line. Lines may become wider or thicker in areas where the object itself is thicker. Or lines may become thicker to help indicate a light source.
What is single line art?
Recently I started making one line drawings. A one line drawing, also known as a single line drawing, is a drawing made with just one line. For most artists it is a way to simplify the complex world around us.
