simplefeatures v0.33.0 Release Notes

  • 2021-10-11

    🚀 Special thanks to Albert Teoh for contributing to this release.

    • 💥 Breaking change: The Envelope type can now be an empty envelope. Previously, it was only able to represent a rectangle with some area, a horizontal or vertical line, or a single point. Its AsGeometry returns an empty GeometryCollection in the case where it's empty. The result of AsGeometry is unchanged for non-empty envelopes.

    • 💥 Breaking change: The NewEnvelope function signature has changed. It now accepts a slice of geom.XY as the sole argument. The behaviour of the function is the same as before, except that if no XY values are provided then an empty envelope is returned without error.

    • 💥 Breaking change: The Envelope type's EnvelopeFromGeoms method has been removed. To replicate the behaviour of this method, users can construct a GeometryCollection and call its Envelope method.

    • 💥 Breaking change: The Envelope type's Min, Max, and Center methods now return Points rather than XYs. When the envelope is empty, Min, Max, and Center return empty points.

    • 💥 Breaking change: The Envelope type's Distance method now returns (float64, bool) rather than float64. The returned boolean is only true if the distance between the two envelopes is defined (i.e. when they are both non-empty).

    • 💥 Breaking change: The Envelope method on the Geometry, GeometryCollection, Point, LineString, Polygon, MultiPoint, MultiLineString, and MultiPolygon types now return Envelope instead of (Envelope, bool). The empty vs non-empty status is encoded inside the envelope instead of via an explicit boolean.

    • The Envelope type now has IsEmpty, IsPoint, IsLine, and IsRectanagle methods. These correspond to the 4 possible envelope categories.
