windkit.map_conversion.poly2lines(poly_gdf, background_lc_id=None, atol=0, complete_polys=False)[source]

Convert a geodataframe of polygons to a geodataframe of lines.

Parameters:

poly_gdf (GeoDataFrame) – A geodataframe including the columns geometry filled with Polygons and id filled with integers or float.
background_lc_id (int or None, optional. Default: None) – When not None, all empty area of the polygon map will be filled with this value. This will be used to create change lines between polygons and empty space.
atol (float, optional. Default: 0) – maximum to distance to consider that two points are at the same place.
complete_polys (bool, optional. Default: False) – Do not rely on the assumptions that neighbour polygons vertices match. Recommended for raster objects. Only has an effect when atol is >0.
