Contour lines may be either traced on a visible three-dimensional model of the surface, as when a photogrammetrist viewing a stereo-model plots elevation contours, or interpolated from the estimated surface elevations, as when a computer program threads contours through a network of observation points of area centroids.
Topographic maps are also commonly called contour maps or topo maps. In the United States, where the primary national series is organized by a strict 7.5-minute grid, they are often called or quads or quadrangles. Topographic maps conventionally show topography, or land contours, by means of contour lines.
Contour plot : A two-dimensional plot which shows the one-dimensional curves, called contour lines on which the plotted quantity q is a constant. Optionally, the plotted values can be color-coded. Optionally, the plotted values can be color-coded.
Contour drawing is an essential technique in the field of art because it is a strong foundation for any drawing or painting; it can potentially modify a subjects’ form through variation within the lines. It is widely accepted among schools, art institutions, and colleges as an effective training aid and discipline [3] for beginner artists. In ...
Each contour line can be defined as a closed line joining relief points at equal height above sea level. [1] It is usually drawn on the same horizontal scale as the map, but the use of an exaggerated vertical scale is advisable to underline the elements of the relief.
Plot structures include a house, private walkways, and at the back - a detached garage with a drive access to the alley and a small area for refuse. In real estate , a land lot or plot of land is a tract or parcel of land owned or meant to be owned by some owner (s).

Contour plowing or contour farming is the farming practice of plowing and/or planting across a slope following its elevation contour lines. These contour line furrows create a water break, reducing the formation of rills and gullies during heavy precipitation and allowing more time for the water to settle into the soil. [ 1 ]
