Calculate distance and bearing between two Latitude/Longitude points using haversine formula in JavaScript

Historypin Great, you've started a collection - now it needs some pins. Great, you've created a tour - now it needs some pins. You can choose from exisiting pins on Historypin. When you see a pin you like, click the repin button: To find pins, browse Historypin or choose them from your own profile. If you want to upload brand new pins, go for it. Computational Geometry, C++ and Wykobi Download source - 108 Kb. Introduction Good C++ computational geometry libraries to date have been hideously over-designed and incorporate usage patterns that in most cases require extensive redesigns and rewrites of code in order to functionally integrate within an existing project. Sometimes a lightweight portable solution that has a bit of error is deemed to be more appropriate and reasonable. However these libraries even though being more than able to cater for such a requirement still burden the end user with undue code clutter, very steep learning curves and in some cases unnecessary overheads. The solution to such a situation is to simplify use, implementation and application.

OpenGL ES 2.0 for iOS, Chapter 3 - Fundamentals of 3D Programming Before we start writing code, we need to go over some of the basics concept and algorithms used in 3D programming. Essentially, we need to make sure we're all speaking the same language. In this chapter, we're going to discuss some of the most basic and fundamental concepts underlying the use of OpenGL ES 2.0, as well as some of the data structures and algorithms that we'll need to create and manipulate virtual three-dimensional objects. We'll talk about what vertices, vectors, polygons, and colors are and how they are represented in OpenGL ES. We'll also look at some of the math that you'll need to perform on each of them.

Directions Service - Google Maps JavaScript API v3 Overview You can calculate directions (using a variety of methods of transportation) by using the DirectionsService object. This object communicates with the Google Maps API Directions Service which receives direction requests and returns computed results. You may either handle these directions results yourself or use the DirectionsRenderer object to render these results. Directions may specify origins and destinations either as text strings (e.g. "Chicago, IL" or "Darwin, NSW, Australia") or as LatLng values. Does leaflet support user defined Layer identifiers If you place all your layers in the same L.featureGroup or L.layerGroup, like this: group = L.featureGroup().addTo(map); L.marker([34.07,-118.29]).addTo(group); L.marker([34.06,-118.28]).addTo(group);[etc., etc....] you can iterate over the layers using the .eachLayer method. This will allow you to create a property of any name you like (say, layerID) and assign a unique value to each layer: To access that ID later, you can use .eachLayer again to find the matching feature and perform whatever task you like on it.

EGSnrc C++ class library: Geometry module This module contains classes that model various geometry types. If you are looking for description of how to define a certain geometry in your input file, click on the corresponding class and see the detailed description. More... Detailed Description This module contains classes that model various geometry types. Panorama Mapping and Tracking Panorama created in real-time on the mobile phone. Summary Tracking for outdoor Augmented Reality (AR) applications has very demanding requirements: It must deliver an accurate registration with respect to a given coordinate system, be robust and run in real time. Despite recent improvements, outdoor tracking still remains a difficult problem.

Google Maps Javascript API V3 Reference - Google Maps JavaScript API v3 Release Version Last updated Saturday, January 30, 2016 This reference documents version 3.23 (the release version) of the Maps Javascript API released Nov 19, 2015. A simple implementation of AJAX You should have the basic express-generator template In app.js, add(you can add it anywhere after var app = express.app()): app.post(function(req, res, next){ next(); }); Now in your index.js file (or its respective match), add:

Does this algorithm have a name? Oct 20, 2010 at 10:47pm Oct 20, 2010 at 8:47pm UTC I do not understand: are you trying to find the area, or the polygon that is the intersection of the two? [Edit:] Second remark: if A is a very small quadrilateral lying entirely inside a very large quadrilateral B, then the intersection in question should be equal to A. I tried to run your algorithm through the so described setup and I don't see how I will get the right answer.
