pyguymer3.geo.clean

pyguymer3.geo.clean(shape, /, *, debug=True, prefix='.', tol=1e-10)[source]

Clean a shape

This function cleans a shape by removing bad points.

Parameters:

  • shape (shapely.coords.CoordinateSequence, shapely.geometry.polygon.LinearRing, shapely.geometry.linestring.LineString, shapely.geometry.multilinestring.MultiLineString, shapely.geometry.polygon.Polygon, shapely.geometry.multipolygon.MultiPolygon) – the shape

  • debug (bool, optional) – print debug messages

  • prefix (str, optional) – change the name of the output debugging CSVs

  • tol (float, optional) – the Euclidean distance that defines two points as being the same (in degrees)

Returns:

cleans – the cleaned shape

Return type:

shapely.coords.CoordinateSequence, shapely.geometry.polygon.LinearRing, shapely.geometry.linestring.LineString, shapely.geometry.multilinestring.MultiLineString, shapely.geometry.polygon.Polygon, shapely.geometry.multipolygon.MultiPolygon

Notes

According to the Shapely documentation for the function shapely.geometry.polygon.orient() :

“A sign of 1.0 means that the coordinates of the product’s exterior ring will be oriented counter-clockwise.”
