GeoBox.from constructor

GeoBox.from(Iterable<Geographic> positions)

A minimum bounding box calculated from positions.

Throws FormatException if cannot create (ie. positions is empty).

Examples:

// a 2D box (lon: 10.0 .. 15.0, lat: 20.0 .. 25.0)
GeoBox.from(
  const [
    Geographic(lon: 10.0, lat: 20.0),
    Geographic(lon: 15.0, lat: 25.0),
  ],
);

// a 3D box (lon: 10.0 .. 15.0, lat: 20.0 .. 25.0, elev: 30.0 .. 35.0)
GeoBox.from(
  const [
    Geographic(lon: 10.0, lat: 20.0, elev: 30.0),
    Geographic(lon: 15.0, lat: 25.0, elev: 35.0),
  ],
);

// a measured 2D box (lon: 10.0..15.0, lat: 20.0..25.0, m: 40.0..45.0)
GeoBox.from(
  const [
    Geographic(lon: 10.0, lat: 20.0, m: 40.0),
    Geographic(lon: 15.0, lat: 25.0, m: 45.0),
  ],
);

// a measured 3D box
// (lon: 10.0..15.0, lat: 20.0..25.0, elev: 30.0..35.0, m: 40.0..45.0)
GeoBox.from(
  const [
    Geographic(lon: 10.0, lat: 20.0, elev: 30.0, m: 40.0),
    Geographic(lon: 15.0, lat: 25.0, elev: 35.0, m: 45.0),
  ],
);

Implementation

factory GeoBox.from(Iterable<Geographic> positions) =>
    Box.createBoxFrom(positions, GeoBox.create);
