Leaflet path example

GeoJSON is becoming a very popular data format among many GIS technologies and services — it's simple, lightweight, straightforward, and Leaflet is quite good at handling it.

In this example, you'll learn how to create and interact with map vectors created from GeoJSON objects. Leaflet supports all of the GeoJSON types above, but Features and FeatureCollections work best as they allow you to describe features with a set of properties. We can even use these properties to style our Leaflet vectors. To create it and add it to a map, we can use the following code:. Alternatively, we could create an empty GeoJSON layer and assign it to a variable so that we can add more features to it later.

The style option can be used to style features two different ways. First, we can pass a simple object that styles all paths polylines and polygons the same way:. Alternatively, we can pass a function that styles individual features based on their properties. In the example below we check the "party" property and style our polygons accordingly:.

Points are handled differently than polylines and polygons. We could also set the style property in this example — Leaflet is smart enough to apply styles to GeoJSON points if you create a vector layer like circle inside the pointToLayer function. A common reason to use this option is to attach a popup to features when they are clicked. To accomplish this we pass a function as the filter option.

This function gets called for each feature in your GeoJSON layer, and gets passed the feature and the layer. You can then utilise the values in the feature's properties to control the visibility by returning true or false. See this example stand-alone.

I have used polyline method of Leaflet to draw the path between the source to destination, but it gives a scrambled path. The latlong in the above code is an array of latitude and longitude points. But it gives a scrambled output like this:.

So let's go! Leaflet is an open-source JavaScript library for interactive web maps. It's lightweight, simple, and flexible, and is probably the most popular open-source mapping library at the moment.

Leaflet is developed by Vladimir Agafonkin currently of MapBox and other contributors. What Leaflet does: "Slippy" maps with tiled base layers, panning and zooming, and feature layers that you supply. It handles various basic tasks like converting data to map layers and mouse interactions, and it's easy to extend with plugins.

It will also work well across most types of devices. See Anatomy of a Web Map for an introduction to the most common kinds of web maps, which is what Leaflet is good for.

What Leaflet does not do: Provide any data for you!

Leaflet is a framework for showing and interacting with map data, but it's up to you to provide that data, including a basemap. If you need total freedom of form, interaction, transitions, and map projections, consider working with something like D3.

How this tutorial works: It's structured around examples that progressively build upon one another, starting from scratch and ending with slightly advanced techniques. It assumes a basic knowledge of HTML and JavaScript, or at the very least assumes the will to tinker with the code to better understand what it does—and how to use it for your own work. It won't explain every little object or array, but will contain plenty of links.

Many code blocks show only a snippet of code, highlighting the changes over previous examples. Click the "View this example on its own" link underneath a map to see complete code.
