    118118Now that everything is setup, we can go on and call our OGR ZOO services with !JavaScript. Please add the following lines after the {{{init()}}} function, which will call the single geometry processes.

    176178Save your HTML file again. You should now be able to select a polygon and to launch a Buffer, !ConvexHull, Boundary or Centroid on it by clicking one of the button. The result of the process should appear as GeoJSON layer on the map, in orange color.
