OpenLayersExt.Control.RoutePlotter

A custom OLE control for editing paths and polygons over an OpenLayersExt.Map.

Functional Description

RoutePlotter is an OLE control that allows users to draw and edit paths and polygons. Drawings can be exported and imported in GML and KML format. This control is added by default to OLE maps. Users can activate the control by clicking on its icon located in the OLE map's main control panel. Once activated, the RoutePlotter panel is shown, offering all the different tools for handling vectors.

Using the Control

This control is added to the map object just as any other standard OpenLayers Control would be added. The official OpenLayers website offers more general information on the use of OpenLayers controls:

  map.addControl( new OpenLayersExt.Control.RoutePlotter() );

Once the control has been added to the map, users will be able to activate the control by clicking on its icon in the map's control panel.
