Smart Mapping

The new Smart Mapping capability introduced in the March 2015 update of ArcGIS Online is also a big part of the 3.13 release of the JavaScript API. Smart Mapping is a new approach that both developers and users of the ArcGIS platform will be able to leverage for making maps that are useful and visually stunning. For more information on Smart Mapping see the Introducing Smart Mapping blog article, Smart Mapping video on esritv, API Reference, and sample below.

Geometry Engine

A new synchronous and asynchronous client-side geometry engine is part of this release. There are over 30 different methods for performing operations that previously would have required a round-trip to a server. For more information on the these new modules, follow the previous links. Note: These features are currently in beta.

], function (Point, geometryEngine, SpatialReference){
  var pt1 = new Point(-118.15, 33.80, new SpatialReference({wkid: 4326}));
  var pt2 = new Point(-119.15, 32.80, new SpatialReference({wkid: 4326}));

  // Using Module to Union
  var union = geometryEngine.union([pt1, pt2]);
  console.log("geometryEngine.union: %o", union);

Search Widget

The Search Widget new at version 3.13 has been designed to provide a single searching and suggestion experience. It allows you to search across multiple Locator and Feature Layer services from a simple interface.
