This node returns a geometry feature containing a simplified representation of each geometry with geopandas.simplify(). The algorithm (Douglas-Peucker) recursively splits the original line into smaller parts and connects these parts’ endpoints by a straight line. Then, it removes all points whose distance to the straight line is smaller than tolerance. It does not move any points and it always preserves endpoints of the original line or polygon.
The node is based on the GeoPandas project and uses the following related information and functions:
Select the geometry column to use.
The simplification tolerance distances for geometry. All parts of a simplified geometry will be no more than tolerance distance from the original. It has the same units as the coordinate reference system of the GeoSeries. For example, using tolerance=100 in a projected CRS with meters as units means a distance of 100 meters in reality.
