--- layout: example-verbatim.html title: Wind shortdesc: Rendering wind velocities with a flow layer. docs: > This example uses a flow layer to render wind velocity. The input wind velocity data is encoded in a PNG, and much of the example code is related to sampling that PNG and generating data tiles representing a velocity field. The first band (or the red channel) of the data tile is the east-west component vector of the wind velocity, and the second band (or green channel) is the north-south component vector. The flow layer is configured with this data tile source and a style for applying a color ramp based on wind speed. experimental: true tags: "wind" --- Wind
