Create an array of globe coordinates based on a limited amounts of points.

rasterGlobe.ts

const rasterGlobe = (limit = 1000, x1 = -180, y1 = -180) => {
  type Coordinates = { x: number; y: number };

  let base = Math.pow(limit, 1 / 2);
  let root = Math.floor(base);
  let data: Array<Coordinates> = [];

  const rasterLine = (x2: number) => {
    for (let i = 0; i < root; i++) {
      let y = y1 + ((y1 * -2) / (root - 1)) * i;
      data.push({ x: x2, y: parseInt(y.toFixed(5)) });
    }
  };

  for (let i = 0; i < root; i++) {
    let x = x1 + ((x1 * -2) / (root - 1)) * i;
    rasterLine(parseInt(x.toFixed(5)));
  }

  return data;
