While Leaflet is meant to be as lightweight as possible, and focuses on a core set of features, an easy way to extend its functionality is to use third-party plugins. Thanks to the awesome community behind Leaflet, there are literally hundreds of nice plugins to choose from. The following plugins allow loading different maps and provide functionality to tile and image layers. Really big ones. The following plugins provide new ways of loading overlay data GIS vector data : points, lines and polygons. Load overlay data from third-party-services. See also basemap providers and plugin collections. These plugins provide new markers or news ways of converting abstract data into images in your screen. Leaflet users versed in GIS also know these as symbolizers. These plugins animate markers or some geometries. See also geometries with time or elevation. The following plugins enable users to interact with overlay data: edit geometries, select areas or features, interact with the time dimension, search features and display information about them. The following plugins help users navigate these extra dimensions. The following plugins enhance or extend L. Display two maps at once. One of them might be a different size and zoom level, usable as a minimap to aid with navigation. The following plugins perform several sorts of geoprocessing mathematical and topological operations on points, lines and polygons. External services that transform an address or the name of a place into latitude and longitude or vice versa. Leaflet keeps it simple. There are no hard requirements on how to create your own plugin, but all developers are encouraged to read the recommendations in the plugin guide. Leaflet Plugins While Leaflet is meant to be as lightweight as possible, and focuses on a core set of features, an easy way to extend its functionality is to use third-party plugins. The plugin provides 96 daily updated layers with satellite imagery and science parameters. Includes lower-level API for deeper integration with other Leaflet plugins. Add Bing Maps tiles to your Leaflet Map. Requires Leaflet v1. Displays map tiles from HERE maps demo. Displays Google maps with minimal artifacts thanks to a DOM mutation observer technique demo. Support for SuperMap services, tiles and more.

Leaflet is the leading open-source JavaScript library for mobile-friendly interactive maps. Leaflet is designed with simplicityperformance and usability in mind. Here we create a map in the 'map' div, add tiles of our choiceand then add a marker with some text in a popup:. Learn more with the quick start guidecheck out other tutorialsor head straight to the API documentation. If you have any questions, take a look at the FAQ first. Leaflet doesn't try to do everything for everyone. Instead it focuses on making the basic things work perfectly. If you find some feature really missing in Leaflet, first check if there's a plugin for it and if it's been discussed before already on GitHub issues. If not, please open a new GitHub issue. Let's create the best mapping library in the world! Leaflet was originally created by Vladimir Agafonkinbut is now developed by a big community of contributors. Pull requests are always welcome. However, there are many more ways to get involved with the development of Leaflet. You can help the project tremendously by discovering and reporting bugsimproving documentationhelping others on Stack OverflowGIS Stack Exchange and GitHub issuestweeting to LeafletJS and spreading the word about Leaflet among your colleagues and friends. Check out the contribution guide for more information on getting involved with Leaflet development. Nov 17, — Leaflet 1. Features Leaflet doesn't try to do everything for everyone. Interaction Features Drag panning with inertia Scroll wheel zoom Pinch-zoom on mobile Double click zoom Zoom to area shift-drag Keyboard navigation Events : click, mouseover, etc. Marker dragging. Visual Features Zoom and pan animation Tile and popup fade animation Very nice default design for markers, popups and map controls Retina resolution support. Misc Extremely lightweight No external dependencies.

First and foremost I would like to express my thanks to Vladimir Agafonkin. He is the driving force behind leaflet. His efforts in bringing Leaflet to the World and constantly improving it are tireless and his altruism in making his work open and available to the masses is inspiring. Vladimir has worked with a large collection of like-minded individuals in bringing Leaflet to the World. These contributors also deserve honours for the work on leaflet. At the time of writing there are over contributors listed on GitHub and the project is listed as used by over 28 thousand other repositories. Those who write the plugins also deserve a special thanks. In the same way that Leaflet provides an excellent framework to work on, the diversity and ingenuity of the available plugins is staggering. There are so many that I am not going to attempt to single any one out for individual praise. Instead, please accept my heartfelt thanks as a group of dedicated individuals. The tile makers. Without the map tiles, there would be no maps. These organisations provide a valuable resource that Leaflet leverages and I would like to recognise them as well. Lastly, I want to pay homage to Leanpub who have made the publishing of this document possible. They offer an outstanding service for self-publishing and have made the task of providing and distributing content achievable. The idea of writing a book on Leaflet came about pretty much as soon as I first used it. It seemed so easy to use and I went looking for some books to help me through some of the more advanced topics. Since they are fairly scarce on the subject inI thought it would be a neat project to write one! This decision has been supported mainly by the success of publishing my first book on d3. When I started writing D3 Tips and Tricks at the end of I had a desire to put out some documentation, but the method was a bit sketchy. I was lucky to stumble upon Leanpub while I was putting information together and it ticked all the boxes I was looking for in terms of being able to publish easily and distribute for free while providing the ability for people to get updates to the book when it gets improved.

Creating An Interactive Map With Leaflet and OpenStreetMap


This reference reflects Leaflet 0. Check this list if you are using a different version of Leaflet. Map properties include interaction handlers that allow you to control interaction behavior in runtime, enabling or disabling certain features such as dragging or touch zoom see IHandler methods. An object literal returned by map. The difference is mostly in zIndex order that such overlays get. Interaction handlers are properties of a marker instance that allow you to control interaction behavior in runtime, enabling or disabling certain features such as dragging see IHandler methods. Used to open popups in certain places of the map. Use Map openPopup to open popups while making sure that only one popup is open at one time recommended for usabilityor use Map addLayer to open as many as you want. Path overlays like polylines also have a bindPopup method. Here's a more complicated way to open a popup on a map:. Used to load and display tile layers on the map, implements ILayer interface. You can use custom keys in the template, which will be evaluated from TileLayer options, like this:. Used to display WMS services as tile layers on the map. Extends TileLayer. Used to create Canvas-based tile layers where tiles get drawn on the browser side. Used to load and display a single image over specific bounds of the map, implements ILayer interface. An abstract class that contains options and constants shared between vector overlays Polygon, Polyline, Circle. Do not use it directly. Set it to false to disable borders on polygons or circles. Set it to false to disable filling on polygons or circles. Doesn't work on canvas-powered layers e. Android 2. Events You can subscribe to the following events using these methods. A class for drawing polyline overlays on a map. Extends Path. Use Map addLayer to add it to the map. MultiPolylines accept all Polyline methods but have different behavior around their coordinate contents since they can contain multiple line features:. A class for drawing polygon overlays on a map.

This reference reflects Leaflet 1. Check this list if you are using a different version of Leaflet. Returns the instance of Renderer that should be used to render the given Path. It will ensure that the renderer options of the map and paths are respected, and that the renderers do exist on the map. Opens the specified popup while closing the previously opened to make sure only one is opened at one time for usability. Closes the popup previously opened with openPopup or the given one. Increases the zoom of the map by delta zoomDelta by default. Decreases the zoom of the map by delta zoomDelta by default. Zooms the map while keeping a specified geographical point on the map stationary e. Zooms the map while keeping a specified pixel on the map relative to the top-left corner stationary. Sets a map view that contains the given geographical bounds with the maximum zoom level possible. Sets the view of the map with a smooth animation like flyTobut takes a bounds parameter like fitBounds. Restricts the map view to the given bounds see the maxBounds option. Sets the lower limit for the available zoom levels see the minZoom option. Sets the upper limit for the available zoom levels see the maxZoom option. Pans the map to the closest view that would lie inside the given bounds if it's not alreadycontrolling the animation using the options specific, if any. Pans the map the minimum amount to make the latlng visible. Use paddingpaddingTopLeft and paddingTopRight options to fit the display to more restricted bounds, like fitBounds. If latlng is already within the optionally padded display bounds, the map will not be panned. Checks if the map container size changed and updates the map if so — call it after you've changed the map size dynamically, also animating pan by default. If options. Tries to locate the user using the Geolocation API, firing a locationfound event with location data on success or a locationerror event on failure, and optionally sets the map view to the user's location with respect to detection accuracy or to the world view if geolocation failed. Stops watching location previously initiated by map. Adds a new Handler to the map, given its name and constructor function. Creates a new map pane with the given name if it doesn't exist already, then returns it. The pane is created as a child of containeror as a child of the main map pane if not set. Returns a plain object containing the names of all panes as keys and the panes as values. Runs the given function fn when the map gets initialized with a view center and zoom and at least one layer, or immediately if it's already initialized, optionally passing a function context. Returns the minimum zoom level of the map if set in the minZoom option of the map or of any layersor 0 by default. Returns the maximum zoom level of the map if set in the maxZoom option of the map or of any layers. Returns the maximum zoom level on which the given bounds fit to the map view in its entirety. If inside optional is set to truethe method instead returns the minimum zoom level on which the map view fits into the given bounds in its entirety. Returns the bounds of the current map view in projected pixel coordinates sometimes useful in layer and overlay implementations. Returns the projected pixel coordinates of the top left point of the map layer useful in custom layer and overlay implementations. Returns the world's bounds in pixel coordinates for zoom level zoom.
