What is CONTOURING? What does CONTOURING mean? CONTOURING meaning, definition & explanation

Contouring * A contour line is a imaginary line which connects points of equal elevations. * The vertical distance between two consecutive contour lines is called contour interval. * Some important characteristics of contours are: 1. Widely spaced contour – flat surface 2. Closely spaced contour – steep ground 3. Equally spaced – uniform slope 4. Approximately concentric closed contours with decreasing values towards centre – pond. 5. Concentric closed contour with increasing values towards centre – hill 6. V-shaped contours with convexity towards higher ground – valley 7. U-shaped contour with convexity towards lower ground – ridge 8. If contour lines meet – existence of cliff or well 9. If contour lines cross – overhanging cliff or cave * Methods of contouring: 1. Direct method: In this method vertical and horizontal contours of the points selected on the selected contour lines are established. 2. Indirect method: The points are selected first and their reduced levels are found. Then...
