Compute elevation bands

class hydrobricks.preprocessing.catchment.Catchment(outline=None)[source]

Bases: object

Creation of catchment-related data

extract_dem(dem_path) → bool[source]

Extract the DEM data for the catchment. Does not handle change in coordinates.

Parameters:

dem_path (str|Path) – Path of the DEM file.

Return type:

True if successful, False otherwise.

get_elevation_bands(method='isohypse', number=100, distance=50)[source]

Construction of the elevation bands based on the chosen method.

Parameters:

  • method (str) – The method to build the elevation bands: ‘isohypse’ = fixed contour intervals (provide the ‘distance’ parameter) ‘quantiles’ = quantiles of the catchment area (same surface; provide the ‘number’ parameter)

  • number (int) – Number of bands to create when using the ‘quantiles’ method.

  • distance (int) – Distance (m) between the contour lines when using the ‘isohypse’ method.

Return type:

A dataframe with the elevation bands.

get_mean_elevation()[source]

Get the catchment mean elevation.

Return type:

The catchment mean elevation.
