min property
The "west-south" geographic position of this bounding box.
For geographic bounding boxes this represents the most southwesterly point. When a bounding box spans the antimeridian, it's possible that "min-longitude" (west) is larger than "max-longitude" (east) as a number. See also RFC 7946 chapter 5 about bounding boxes in GeoJSON for reference.
Implementation
@override
Geographic get min => Geographic(
lon: _west,
lat: _south,
elev: _minElev,
m: _minM,
);
