wind-js-leaflet

A plugin for Leaflet to add visualisation overlay of wind direction, wind velocity, and temperature. To use this plugin, you will need to run your own wind-js-server instance. The data is 1 degree, 6 hourly data from NOAA.

leaflet-velocity released

Consider using leaflet-velocity instead of wind-js-leaflet, as it is more flexible and up to date.

v2 Breaking Changes

Now supports both leaflet version 0.7.7 and 1.0.3. However this update brings one breaking change - how you initialise the plugin.

v1 way to init:

WindJSLeaflet({ options: 'here' });

v2 way to init:

WindJSLeaflet.init({ options: 'here' });
