D3 + Leaflet. This is a quick demonstration of using D3 to render GeoJSON shapes in conjunction with Leaflet.
The implementation is straightforward, but Leaflet is regretfully missing documentation and examples for custom overlays, [EDIT: the documentation has since been updated and there is now a helpful section titled “Implementing Custom Layers”] so hopefully this will help you get started. #Initializing the Map and SVG Overlay We’ll start with a basic map using MapBox tiles: The map is placed inside a paragraph (p) element with the id “map”. An associated stylesheet specifies the dimensions: Leaflet/Leaflet.label. Mlevans/leaflet-hash. Turbo87/leaflet-sidebar. Makinacorpus/django-leaflet. Yohanboniface/Leaflet.Storage.
Ben.Knows.Code(): Using Google Maps Drawing Manager to Create User Selectable Areas. The Google Maps API has been on my list of things to learn for some time now.
I recently had an opportunity to dive in and try a few features out. There's a lot of good documentation and small demos available from Google which makes it pretty easy to get started. I decided to create a simple scenario where, given a set of places marked on the map, the user can select a region of interest and list more details about the points inside the selected area. I started this experiment with the Drawing Tools demo, tweaking it, and adding various different features. There are several pieces needed to make it work: Create the map and center it Plot all the points the user can select Create the DrawingManager, tell it what to draw, and then listen for it to complete drawing that object Each time a selection is made, find the points inside the area and list them next to the map Maintain only one selection area. API 2.0: Introduction. What are the pros and cons of each "Places" API?
I blogged about Leaflet soon after it was first released and that post has been read by a lot of people and has generated more comments than any other. Computing Distances. Angularjs - Changing list-item css class using ng-class when mousing over Leaflet Map Markers. LEAFLET - store and retrieve user markers & diagrams from database. I am intending to use leaflet in order to build a "microscope laboratory" for my institute's medical school.

Die APIs der beiden Marktführer machen es Entwicklern leicht, das verfügbare Kartenmaterial in eigene Apps oder Webseiten zu integrieren. Ein einfaches HTML-Gerüst mit klickbarer Karte dient diesem Artikel als Beispiel für eine Entfernungsberechnung, wie sie mobile Nomaden etwa für die monatliche Spesenabrechnung brauchen. Rate Limits. Usage of the API is subject to rate limits. The limits are based on a moving window that tracks the number of requests you send per hour. An application can make up to 5,000 userless requests per hour to venues/* endpoints. An application can make up to 500 userless requests to most other endpoints groups per hour. Geographischer Mittelpunkt. Was ist der geographische Mittelpunkt? Orthodrome. Der kürzeste Weg auf der Kugeloberfläche zwischen Punkt A und B ist eine Orthodrome. Calculate distance between two points in google maps V3. Smallest-circle problem. The smallest-circle problem in the plane is an example of a facility location problem (the 1-center problem) in which the location of a new facility must be chosen to provide service to a number of customers, minimizing the farthest distance that any customer must travel to reach the new facility. Both the smallest circle problem in the plane, and the smallest bounding sphere problem in any higher-dimensional space of bounded dimension, may be solved in linear time.
Characterization Most of the geometric approaches for the problem look for points that lie on the boundary of the minimum circle and are based on the following simple facts: The minimum covering circle is unique.The minimum covering circle of a set S can be determined by at most three points in S which lie on the boundary of the circle. If it is determined by only two points, then the line segment joining those two points must be a diameter of the minimum circle. Das 1-Center-Problem. Design and publish beautiful maps. TileMill.

The haversine formula is an equation important in navigation, giving great-circle distances between two points on a sphere from their longitudes and latitudes.
It is a special case of a more general formula in spherical trigonometry, the law of haversines, relating the sides and angles of spherical triangles. The term haversine was coined in 1835 by Prof. The next most obvious thing.
