Hypsometric Curve
This plugin calculates the hypsometric curve of a drainage basin using a DEM raster layer and a vector polygon representing the basin boundary. It computes elevation intervals, partial and cumulative areas, minimum, maximum and mean elevation, and the Hypsometric Integral (HI). The plugin also generates the hypsometric curve graph and provides export options for both the table and the graph. Includes full QGIS 4 compatibility, robust CRS handling, improved raster masking, corrected HI computation, and customizable graph colors. Requires NumPy and Matplotlib.
Calculate the hypsometric curve of a drainage basin starting from a DEM and a polygon representing the basin boundary. The plugin computes elevation intervals, partial and cumulative areas, h_min, h_max, h_med, and the Hypsometric Integral (HI). It also generates the hypsometric curve graph and allows exporting both the table and the plot. Fully compatible with QGIS 4 and Qt6.
