Tasokäyristä

Tasokäyristä refers to the process of creating contour lines on a map or diagram. These lines connect points of equal value, representing a continuous surface. In cartography, tasokäyristä is primarily used to depict elevation, with contour lines showing areas of the same altitude above sea level. The closer the contour lines are to each other, the steeper the terrain. Conversely, widely spaced lines indicate gentler slopes.

Beyond topographical maps, tasokäyristä can be applied to various fields. In meteorology, isobars are contour lines connecting points of equal atmospheric pressure. Isotherms connect points of equal temperature, and isohyets connect points of equal rainfall. In engineering and design, tasokäyristä can visualize stress distributions or fluid flow patterns. The fundamental principle remains the same: illustrating how a measured quantity changes across a two-dimensional plane. The interpretation of tasokäyristä relies on understanding the specific quantity being represented and the interval between the lines, often indicated in a map legend.
