HYPSOMETRIC CURVES
|
|
==================
|
|
|
|
Description
|
|
-----------
|
|
Calculate hypsometric curves for features of polygon layer and save them as
|
|
CSV file for further processing.
|
|
|
|
Parameters
|
|
----------
|
|
|
|
- ``DEM to analyze [Raster]``: DEM to use for calculating altitudes.
|
|
- ``Boundary layer [Vector]``: Polygonal vector layer with boundaries of areas
|
|
used to calculate hypsometric curves.
|
|
- ``Step [Number]``: Distanse between curves. Default is 100.0
|
|
- ``Use % of area instead of absolute value [Boolean]``: Write area percentage
|
|
to "Area" field of the CSV file instead of absolute area value.
|
|
|
|
Outputs
|
|
-------
|
|
|
|
- ``Output directory [Directory]``: Directory where output will be saved. For
|
|
each feature from input vector layer CSV file with area and altitude values
|
|
will be created.
|
|
|
|
File name consists of prefix "hystogram_" followed by layer name and feature
|
|
ID.
