cartagen.regularize_building_rectangle

regularize_building_rectangle(polygon, factor=1.0, method='mbr')

Transform a polygon into a rectangle.

This function transforms a polygon to a rectangle using the minimum rotated rectangle and scale it up or down.

Parameters:

• polygon (Polygon) – The polygon to regularize.

• factor (float, optional) – The scaling factor to apply.

• method (str, optional) –

  The method to calculate the rectangle:

  • ’mbr’ calculate the minimum rotated bounding rectangle.

  • ’mbtr’ calculate minimum rotated bounding touching rectangle. It is the same as the mbr but the rectangle and the polygon must have at least one side in common.

Returns:

Polygon
