A Leaflet plugin that allows to add elevation profiles using d3js
For a working example see one of the following demos:
- loading .gpx file
- loading .geojson file
- loading .kml file
- loading .tcx file
- loading a local .gpx file
- loading data from a textarea
- loading individual .geojson tracks
- loading individual .gpx tracks
- loading multiple .gpx tracks (hover to toggle)
- loading multiple .gpx tracks (click to toggle)
- loading multiple maps
- translating plugin labels
- rotating chart labels
- using custom colors
- using .gpx extensions (cadence, heart, pace)
- using .gpx waypoint icons
- using .geojson waypoint icons
- autohide map
- autohide chart
- clear button
- collapsible button
- custom summary
- edge scale control
- follow marker
- layer almostover
- linear gradient
- slope chart
- speed chart
- temperature chart
- walking marker
Initially based on the work of Felix “MrMufflon” Bache
- include CSS & JavaScript
<head> ... <style> html, body, #map, #elevation-div { height: 100%; width: 100%; padding: 0; margin: 0; } #map { height: 75%; } #elevation-div { height: 25%; font: 12px/1.5 "Helvetica Neue", Arial, Helvetica, sans-serif; } </style> <!-- leaflet-ui --> <script src="https://unpkg.com/leaflet@1.7.1/dist/leaflet.js"></script> <script src="https://unpkg.com/leaflet-ui@0.6.0/dist/leaflet-ui.js"></script> <!-- leaflet-elevation --> <link rel="stylesheet" href="https://unpkg.com/@raruto/leaflet-elevation/dist/leaflet-elevation.css" /> <script src="https://unpkg.com/@raruto/leaflet-elevation/dist/leaflet-elevation.js"></script> ... </head>
- choose the div container used for the slippy map
<body> ... <div id="map"></div> ... </body>
- create your first simple “leaflet-elevation” slippy map
<script> // Full list options at "leaflet-elevation.js" var elevation_options = { // Default chart colors: theme lime-theme, magenta-theme, ... theme: "lightblue-theme", // Chart container outside/inside map container detached: true, // if (detached), the elevation chart container elevationDiv: "#elevation-div", // if (!detached) autohide chart profile on chart mouseleave autohide: false, // if (!detached) initial state of chart profile control collapsed: false, // if (!detached) control position on one of map corners position: "topright", // Toggle close icon visibility closeBtn: true, // Autoupdate map center on chart mouseover. followMarker: true, // Autoupdate map bounds on chart update. autofitBounds: true, // Chart distance/elevation units. imperial: false, // [Lat, Long] vs [Long, Lat] points.

Within your local development environment:
git clone git@github.com:Raruto/leaflet-elevation.git
cd ./leaflet-elevation
npm i # install dependencies
npm run dev # start dev server at: http://localhost:8080
npm run build # generate "dist" files (once)
npm run test # test all "*.spec.js" files (once)After that you can start developing inside the src and test folders (eg. open "http://localhost:8080/test" in your browser to preview changes). Check also CONTRIBUTING.md file for some information about it.
1. How can I change the color of the elevation plot?
There are multiple options to achieve this:
- You could either use some default presets (see: theme: "lightblue-theme" option in readme file and the following file
leaflet-elevation.cssfor some other default "*-theme" names). - check out this example
- Or add the following lines for custom colors.
.elevation-control .area {
fill: red;
}
.elevation-control .background {
background-color: white;2. How to enable/disable the leaflet user interface customizations?
These customizations are actually part of the leaflet-ui and can be toggled on/off using e.g. the following options:
var map = L.map('map', {
center: [41.4583, 12.7059], // needs value to initialize
zoom: 5, // needs value to initialize
mapTypeId: 'topo',
mapTypeIds: ['osm', 'terrain', 'satellite', 'topo'],
gestureHandling: false, // zoom with Cmd + Scroll
zoomControl: true, // plus minus buttons
pegmanControl: false,
locateControl: false,
fullscreenControl: true,
layersControl: true,
minimapControl: false,
editInOSMControl: false,
loadingControl: false,
searchControl: false,
disableDefaultUI: false,
printControl: false,
});3. How can I import this library as ES module?
Usually, when working with a js bundler like Vite or Webpack, you need to provide to this library the full path to some dynamically imported files from the srcFolder:
import './your-custom-style.css';
import 'leaflet/dist/leaflet.css';
import L from 'leaflet';
import '@raruto/leaflet-elevation/src/index.js';
import '@raruto/leaflet-elevation/src/index.css';
const map = L.map('map', {
center: [41.4583, 12.7059]
zoom: 5,
});
const controlElevation = L.control.elevation({
// CHANGE ME: with your own http server folder (eg. "http://custom-server/public/path/to/leaflet-elevation/src/")
srcFolder: 'http://unpkg.com/@raruto/leaflet-elevation/src/'
}).addTo(map);
// Load track from url (allowed data types: "*.geojson", "*.gpx", "*.tcx")
controlElevation.load("https://raruto.github.io/leaflet-elevation/examples/via-emilia.gpx");4. Some real world projects based on this plugin?
