Removes the loops from a lineString (Test to outline a lineString without having weird overlaps) Please note that this algorithm is not optimized for performance. I recommend only using it in command line tools

stephanbogner / convertAndInvertProjection.js

Created July 18, 2017 11:34

Simple example to convert coordinates from one projection into another one

	// import
	// - https://d3js.org/d3-geo.v1.min.js
	// - https://d3js.org/d3-geo-projection.v2.min.js

	// Keep x and y in the same range of values as coordinates
	var x = 180;
	var y = 90;
	var fromXY = [x, y];
	var fromLonLat = d3.geoEquirectangular().invert(fromXY);
	var toXY = d3.geoMercator()(fromLonLat);

Snippets writing apps with gyroscope and GPS

	function getAngleBetweenVectorAndPlane(vector, plane) {
	var angle = Math.asin(Math.abs(plane.x * vector.x + plane.y * vector.y + plane.z * vector.z) / (Math.sqrt(Math.pow(plane.x, 2) + Math.pow(plane.y, 2) + Math.pow(plane.z, 2)) * Math.sqrt(Math.pow(vector.x, 2) + Math.pow(vector.y, 2) + Math.pow(vector.z, 2))));
	// http://www.vitutor.com/geometry/distance/line_plane.html
	var direction = -vector.z / Math.abs(vector.z); // Because vector angle is always shortest and has no direction
	angle = angle * direction * 180 / Math.PI;
	return angle;
	}
