momepy.orientation#

momepy.orientation(geometry)[source]#

Calculate the orientation of objects.

The ‘orientation’ is defined as the deviation of orientation of the bounding rectangle from cardinal directions. As such it is within a range 0 - 45. The orientation of LineStrings is represented by the orientation of the line connecting the first and the last point of the segment.

Parameters:

geometryGeoDataFrame | GeoSeries: A GeoDataFrame or GeoSeries containing polygons to analyse.

Returns:

Series
