Isokontuurit, often translated as isocontours or contour lines, are graphical representations used to depict a scalar field in two or three dimensions. They are lines or surfaces that connect points of equal value within that field. The concept is widely applied across various scientific and engineering disciplines.

In cartography, isocontours are familiar as contour lines on topographic maps, connecting points of equal elevation above sea level. These lines help visualize the shape and steepness of the terrain. Similarly, in meteorology, isobars connect points of equal atmospheric pressure, and isotherms connect points of equal temperature, aiding in weather forecasting.

The generation of isocontours typically involves interpolation techniques to estimate values between known data points. Algorithms like the marching squares algorithm are commonly used for generating 2D isocontours, while its 3D counterparts are employed for surfaces. The spacing and curvature of isocontours directly indicate the rate of change in the scalar field; closely spaced lines suggest a rapid change, while widely spaced lines indicate a gradual change. Isocontours are a powerful visualization tool for understanding spatial variations in data.
