BoundingBox class
A BoundingBox is a rectangular region in a coordinate system, generally used to define the extent of a Feature or FeatureCollection. A BoundingBox can be created from a Coordinate or a WKT String.
Example:
BoundingBox(1, 2, 3, 4); // BoundingBox(1, 2, 3, 4)
BoundingBox(1, 2, 3, 4).toWKT(); // POLYGON((1 2, 3 2, 3 4, 1 4, 1 2))
Constructors
- BoundingBox(double minLong, double minLat, double maxLong, double maxLat)
- BoundingBox.empty()
-
Creates an empty BoundingBox.
This is the default value for BoundingBoxs.
factory
-
BoundingBox.fromCoordinates(List<
Coordinate> coordinates) -
Creates a BoundingBox from a List of Coordinates.
The List must contain at least two Coordinates.
It's very similar to
BoundingBox.fromPoints, but it's designed for use with Coordinates.factory -
BoundingBox.fromPoints(List<
Point> points) -
Creates a BoundingBox for a List of Coordinates.
The List must contain at least two Coordinates.
