LngLatRectangle

A longitude-latitude rectangle on an ellipsoid. Angular values are stored in radians.

Usage​

import {toRadians} from '@math.gl/core';
import {LngLatRectangle} from '@math.gl/geospatial';

const rectangle = new LngLatRectangle(
  toRadians(170),
  toRadians(-10),
  toRadians(-170),
  toRadians(10)
);

const center = LngLatRectangle.center(rectangle);

Because east is smaller than west, this example crosses the antimeridian and has a width of 20 degrees.

Fields​

west : Number​

The westernmost longitude in radians.

south : Number​

The southernmost latitude in radians.

east : Number​

The easternmost longitude in radians.

north : Number​

The northernmost latitude in radians.

width : Number​

The rectangle width in radians, accounting for antimeridian crossing.

Methods​

constructor(west : Number, south : Number, east : Number, north : Number)​

Creates a longitude-latitude rectangle.

LngLatRectangle.center(rectangle : LngLatRectangle, result? : Vector3) : Vector3​

Computes the rectangle center. The returned vector contains longitude, latitude, and a zero height.

  • rectangle - The rectangle whose center should be computed.
  • result - Optional Vector3 in which to store the result.

Returns the supplied result or a new Vector3.
