contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level Numbers on the lines give the height in feet (Sea level is zero) Lines drawn closely together indicate that a slope is steep
What do contour lines describe in art?
A contour line defines the outline of a form, as well as interior structure, without the use of shading A fundamental basis of drawing, contour lines are usually the first technique children adopt to draw people, houses, and trees
What do contour lines provide?
Contour Lines: Contour lines are used to determine elevations and are lines on a map that are produced from connecting points of equal elevation (elevation refers to height in feet, or meters, above sea level)
What is contouring What are the characteristics and uses of contour lines?
Contouring in surveying is the determination of elevation of various points on the ground and fixing these points of same horizontal positions in the contour map
How do you describe a contour map?
a topographic map on which the shape of the land surface is shown by contour lines, the relative spacing of the lines indicating the relative slope of the surface
Why are contour lines useful?
Contour lines are very important in teaching natural sciences because they represent relief in an accurate way Relief is controlled by rock type and geological structures These two factors influence in the location and shape of rivers, which in terms, help the development of soils and vegetation
Why are contour lines important in art?
The purpose of contour drawing is to emphasize the mass and volume of the subject rather than the detail; the focus is on the outlined shape of the subject and not the minor details
What are the main characteristics of contour lines?
Characteristics of Contours Must close on themselves, on or off the map Perpendicular to the direction of max Slope between them is assumed uniform The distance between them indicates the steepness of the slope, gentle or steep Irregular signify rough, smooth signify gradual slopes
What is contour line and its characteristics?
A contour line is an imaginary line which connects points of equal elevation Such lines are drawn on the plan of an area after establishing reduced levels of several points in the area The contour lines in an area are drawn keeping difference in elevation of between two consecutive lines constant
What characteristic of contour lines indicates steep terrain?
Closely spaced contour lines indicate a steep slope (Figure F-1) 2 Widely spaced contour lines indicate a gentle slope (Figure F-2)
How do contour lines work?
Contour lines connect points that share the same elevation: Where they’re close together (they never intersect), elevation is changing rapidly in short distance and the terrain is steep Where contour lines are wide apart, elevation is changing slowly, indicating a gentle slope
How do you describe topography?
Topography describes the physical features of an area of land These features typically include natural formations such as mountains, rivers, lakes, and valleys Manmade features such as roads, dams, and cities may also be included Topography often records the various elevations of an area using a topographical map
What is meant by contour in geography?
Definition: Contours are a collection of lines found on maps that show mountains, valleys and landforms Contours are measured from sea level Contours can be used to understand the map and to know where land will be steep or flat
What are contour lines and how they are useful?
Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain constant Contour lines show elevation and the shape of the terrain They’re useful because they illustrate the shape of the land surface — its topography — on the map
What is a contour line in art for kids?
A contour drawing is a line drawing Lines define every edge of an object with no shading Kids naturally draw outline type drawings because they are the simplest form of drawing
What is contour shading?
The shading describes the three-dimensional form, and it’s absence creates the highlights The lighting suggests a rounded form, so the straight vertical lines create confusion Wherever possible,let your hatching follow the form of the object you’re drawing This is often called Contour Hatching
What artist used contour lines?
Artists such as Leonardo da Vinci have used contours in their sketches, while Henri Matisse employed the use of dark lines to outline his jubilant figures in The Dance
What are the characteristics of contour explain with neat sketch?
Contour line is closer near the top of a hill or high ground and wide apart near the foot This indicates a very steep slope toward the peak and flatter slope toward the foot 2 Contour line is closure near the bank of a pond or depression and wide apart toward the centre
What is contour in civil engineering?
Contour • An imaginary line on the ground surface joining the points of equal elevation is known as contour • In other words, contour is a line in which the ground surface is intersected by a level surface obtained by joining points of equal elevation
What do you understand the term contour also explain?
: a line (as on a map) connecting the points on a land surface that have the same elevation
How are contour lines used in construction?
It is the line on a plan or map that represents those points that have the same height, that is to say, they have the same altitude, in relation to a reference plan They must not intersect or coincide, except in vertical walls and cornices, as the higher they are the less developed they are
What is a contour explain the spacing pattern of the contour and list its basic characteristics?
Spacing of contours: close contours indicate a steep slope; distant contours a shallow slope Two or more contour lines merging indicates a cliff By counting the number of contours that cross a segment of a stream, the stream gradient can be approximated
How do you identify a contour line?
What does contour mean in drawing?
contour drawing, version of outline drawing, in which the artist, looking closely at the contour of an object, transfers it in one continuous line to paper without looking down to see what he is doing, except when he needs to place an internal feature such as an eye
What do contour lines represent on a topographic map?
Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes
What is the definition for topographical?
Definition of topographical 1 : topographic 2 : of, relating to, or concerned with the artistic representation of a particular locality a topographical poem topographical painting
