## parcel_mrr_area_ratio

{% docs column_parcel_mrr_area_ratio %}
Ratio of the parcel's area to the area of its
[minimum rotated bounding rectangle](https://en.wikipedia.org/wiki/Minimum_bounding_rectangle).
Ratio of the parcel's area to the area of its minimum rotated bounding
rectangle.

The goal of this feature is to identify parcels with interior holes or strange
concave shapes, e.g. `16-01-402-008` (basically a right angle parcel).

[See here](https://en.wikipedia.org/wiki/Minimum_bounding_rectangle) for an
explanation of minimum rotated bounding rectangles.

## parcel_mrr_side_ratio

{% docs column_parcel_mrr_side_ratio %}
Ratio of the longest to the shortest side of the parcel's
[minimum rotated bounding rectangle](https://en.wikipedia.org/wiki/Minimum_bounding_rectangle).
Ratio of the longest to the shortest side of the parcel's minimum rotated
bounding rectangle.

The goal of this feature is to identify parcels with consistent, square shapes.
In practice, parcels with a high ratio tend to have long, extraneous
elements/slivers, e.g. `02-23-311-027`.

[See here](https://en.wikipedia.org/wiki/Minimum_bounding_rectangle) for an
explanation of minimum rotated bounding rectangles.
