Release notes for 4.7

April 2018

WebGL rendering updates

FeatureLayers are now rendered with WebGL by default as of version 4.9.

  • FeatureLayer performance continues to improve, allowing you to load features more efficiently and navigate the view more seamlessly.
  • FeatureLayerView can now be queried when WebGL is enabled.
  • TextSymbol is now supported with FeatureLayers. This includes support for multi-line text.

Client-side projection

The new projection module provides an engine for converting geometries from one spatial reference to another client-side. To see how this is done, please refer to the Client-side projection sample. The browser must support WebAssembly for the client-side engine to work. The new Coordinate Conversion widget and Coordinate formatter module takes advantage of this functionality.

Mobile support in 3D

WebScenes are now supported on modern mobile devices enabling developers to build 3D web applications that can be used on phones or tablets without needing to install an app. See Hardware requirements for 3D for more information on supported devices.

Edge rendering for 3D Object SceneLayer

Perception of object shapes in 3D is now improved by rendering contour edges of buildings and extruded polygons. The new edge properties on FillSymbol3DLayer within MeshSymbol3D and on ExtrudeSymbol3DLayer within PolygonSymbol3D can be used to activate edge rendering and to set the color of the edges. Edges can have two different styles: SolidEdges or SketchEdges3D for lines that should look more hand-drawn.

Widget updates

Coordinate Conversion widget

The CoordinateConversion widget provides a way to display user cursor position either as map coordinates or as any of several popular coordinate notations. To see this widget in action, please refer to the CoordinateConversion widget and CoordinateConversion widget - Custom Formats samples.

3D Area Measurement widget

Areas can be measured in 3D using the AreaMeasurement3D widget. To see how to use this widget or the DirectLineMeasurement3D widget, see the Measurement in 3D sample.

Legend widget card style

The Legend widget now has a style property allowing you to toggle between two different views of the widget. We added support for a new card style, which displays widget content in a fresh, different way.

new-legend

The card style is also responsive, collapsing to a different layout depending on the view size. This makes it an ideal style for mobile devices.

LayerList updates

We added support for panels in the LayerList widget. This allows you to add custom content to a layer's list item, including: widgets, text, and DOM elements specific to the application. Check out these samples, which demonstrate how to add additional content types to LayerList panels:

layerlist-chart

We removed the createActionsFunction property from LayerList and LayerListViewModel classes. This is a breaking change. Use listItemCreatedFunction instead.

Draw updates

  • SketchViewModel now has support for creating rectangle, square, circle and ellipse shapes. These shapes are created with the help of SegmentDrawAction under the hood.
  • SketchViewModel now has support for updating temporary geometries. You can now move the entire geometry or move one or more vertices at a time. See the updated Sketch temporary geometries sample.
  • Draw and SketchViewModel now have support for different drawing modes when creating Polygon and Polyline geometries.

Custom builds with npm and webpack

You can now use both npm and webpack to create custom builds of the ArcGIS Maps SDK for JavaScript. This allows you to take advantage of modern web development tooling to build your web applications. See the Using Webpack for Custom Builds guide page for more information.

Better support for ES promises

This release improves our compatibility with ES Promises. Prior to 4.7, the WebMap, WebScene, MapView, SceneView, Basemap, Ground, Layer, and LayerView classes were not compatible with ES Promises. At this release, we make the API compatible by default. This is a breaking change. Please read this blog post to learn more about how to make your code compatible with these updates.

Smart Mapping updates

The Smart Mapping renderer creator methods now support generating renderers with the following:

Arcade expressions are referenced with the new valueExpression parameter in each of the creator methods.

FeatureLayer updates

  • FeatureLayer can now be constructed with dynamic data sources (with data either from map service sublayers or data from a registered workspace) by passing the appropriate data source to the dynamicDataSource property.
  • FeatureLayers pointing to dynamic data sources can also be conveniently created using the createFeatureLayer() method on a Sublayer instance already containing the same configuration. See the MapImageLayer - Explore data from a dynamic workspace sample for an example of the createFeatureLayer() method.

CSVLayer updates

CSVLayers are now rendered with WebGL by default as of version 4.9.

CSVLayer can now be rendered using WebGL. This allows you to render more data in the browser and update the visualization of features more rapidly. To enable WebGL for rendering CSVLayer (and FeatureLayer), paste the following script in your application prior to loading the ArcGIS Maps SDK for JavaScript.

</script>

This CSV sample demonstrates how to enable WebGL rendering for a CSVLayer.

csv layer

Other CSVLayer updates include:

  • Added support for definitionExpression, allowing you to filter data directly on the layer.
  • Added support for querying features and statistics on the layer instance.
  • You can now generate renderers for CSVLayer with the Smart Mapping modules.

Mesh geometry

Mesh geometry is a new type of geometry, similar to point, polyline and polygon. It allows users to create 3D geographical objects by directly manipulating vertices, connecting them into faces and mapping corresponding textures. See the Low poly terrain using mesh geometry and Working with 3D mesh primitives to understand how to use it.

Thumbnails for attachments in popup

For services that support it, and supported file types, the popup will display thumbnails for image attachments.

layerlist-chart

Coordinate formatter

The new coordinateFormatter module allows users to convert between Points and formatted coordinates notation strings such as:

  • decimal degrees
  • degrees, minutes, and seconds
  • U.S. National Grid (USNG)
  • Military Grid Reference System (MGRS).
