OpenLayers Editor (ole) provides a set of controls for extended editing of spatial data.
editor = new OpenLayers.Editor(map, {
activeControls: ['SnappingSettings', 'SplitFeature', 'MergeFeature', 'CleanFeature'],
featureTypes: ['polygon', 'path', 'point', 'text']
});
editor.startEditMode();
See /examples
for some inspiration.
Some controls like merge, split and clean depend on server-side processing.
Examples for server-side processing and CRUD operations are available for several backends:
Set editor.oleUrl
according to your server configuration.
