Example

An example of the usage:

// Connect as anonymous user to a geoapps environment
geoapps.Initialize("<specified tenant>");

// Add the map to a div with element id `map`
var map = geoapps.AddMap("map", "<mapId>");

// Wait till the map loaded, before starting the draw actions
map.onLoaded.add(() => {
   // Drawing
   map.Drawing.onLoaded.add(function () {
     console.log(map.BaseLayers.items);
   });

   // Add feature
   map.Drawing.AddFeature(<wkt>, <attributes>);

   // Delete feature
   map.Drawing.DeleteFeature(<featureId>);

   // Get split feature
   map.Drawing.GetSplitFeatures(<layerItemId>, <targetFeature>, <splitFeature>);

   // Split feature
   map.Drawing.Split(<layerItemId>, <targetFeature>, <splitFeature>, <options>);

   // Start editing
   map.Drawing.StartEdit(<LayerId>);

   // Update attributes editing
   map.Drawing.UpdateAttributes(<layer>, <selectedFeature>);
});
