Isohyetal lines are mainly based on interpolation between rain gauge stations. Isohyets are then drawn to create an isohyetal map. The method allows for the plotting of rainfall values on a proper basemap at their respective stations. Additionally, an isohyetal method uses topographic data together with other data to come up with authentic estimates. The method is used when drawing lines of equal precipitation on a map. The method used in estimating average rainfall across a particular area is known as an isohyetal method. Isohyetal LinesĪn isohyet is also known as isohyetal line, and it is a line on a map which connects points that have the same amounts of precipitation in a given period or for a particular storm. The lines are named following the nature of the variable that is being mapped even though the phrase ‘contour line’ is applied in many usages. There are different types of counter lines, and they are often given a specific name which begins with ‘iso’ which is an ancient Greek term meaning equal. Contour lines could either be straight, curved, or a mixture of both lines on a map, and they describe an intersection of a hypothetical or real surface with one or more horizontal planes.

If contour lines are found close to each other, then the magnitude of the gradient increases, implying the variation will be elevated. The function’s gradient is perpendicular to the contour lines at all times. A contour line is always a function of two variables and is depicted as a curve that connects the points where the function has the same value.

A contour line is also known as an isarithm, isoline, or isopleth, and it is contour line on a map which represents an imaginary line on the land’s surface.
