- In This Tutorial, I wil present how to create Hypsometric Curve in ArcGIS
The hypsometric curve is the graph on the right hand side of this page. This curve is typically used to demonstrate that the Earth has two types of crust, continental and oceanic. The curve shows the percentage of the Earth's surface above any elevation. The horizontal axis, labeled "% of Earth's surface," gives the percentage while the vertical axis shows elevation above or below sea level.
Hypsometry is the measurement of the land elevations which is relative to the sea level. The representation of such a measurement is the hypsometric curve. The hypsometric curve defines the elevations of the earth’s surface in the form of cumulative distribution. And the graph given above in the form of a two-dimensional histogram shows the elevation on the vertical y-axis and the area above the corresponding elevation is shown on the x-axis. It is clearly visible from the figure that the hypsometric curve is the cumulative height frequency curve of the Earth’s surface. Thus, in simple terms hypsometry is the calculation or the measurement of the land elevations and the hypsometric curve is the graphical representation of the frequency distributions (cumulative) of the elevations of the earth’s surface.
As is clear from the given definitions, hypsometry is the measurement of the high risen or highly deep points on the earth surface and hypsometry is the graphical representation of the same. As clearly visible, the hypsometric curve gives two humps of maxima in the cumulative distribution of elevation in Earth’s surface, one at 100 metre and another at 4700 metres which indicate the correlations with the mean level of the lowland continental areas and the deep sea-floor. The interesting thing about the hypsometric analysis of Earth’s surface is that it supports the theory that the crust of the Earth’s surface consists of simatic materials under the ocean and of sialic materials above the ocean i.e. the surface of the continents.
Application:
The hypsometric curves are usually commonly used in limnology. In limnology, the relationship between the surface area of the lake and the depth is represented by the curve and is used to calculate the total lake volume. The graphs of the curve will be used to predict other different characteristics of the lakes like productivity, dilution of the incoming
chemicals and the potential mixing for the water.
