Release notes for 200.2

This page provides details about enhancements in the 200.2 release of ArcGIS Maps SDK for Qt. It also lists deprecations, resolved issues, known issues, and more.

Enhancements

Scene layers

Filter features in 3D object and point scene layers

Scene layers of type 3D object or point scene layer now support filtering by features and by area. Support includes web scenes published containing scene layers with filtered features. Features can be filtered using one of the following new methods on the ArcGISSceneLayer class:

Filter scene layer with IDs

Features in scene layers can also be filtered spatially using one or more polygon areas. A new class called SceneLayerPolygonFilter defines a filter from a set of polygons and a spatial relationship. The spatial relationship determines whether to show only those features inside the filter area or those outside the specified area. The filter is applied to the ArcGISSceneLayer via a new polygonFilter property.

Filter scene layer with IDs

Support for relative to ground surface placement mode

Scene layers of type 3D object scene layer or point scene layer now support features with a surface placement mode value of Relative (relative to the ground surface). This enhancement adds initial support for a new collection of global 3D scene layers. With this release, the Living Atlas layer OpenStreetMap 3D Buildings (Beta) can now be used in your 3D scenes.

Edge rendering

This release completes support for displaying edges on 3D object scene layers across all Native Maps SDKs and on all platforms.

Edges are now rendered on 3D object scene layers for iOS and macOS apps built with ArcGIS Maps SDK for Qt.

Real-time

Support for custom feeds

With this release of ArcGIS Maps SDK for Native Apps, you can create a custom DynamicEntityDataSource. This new API allows you to bring data from custom feeds that you manage into a DynamicEntityDataSource as dynamic entities. You can visualize them in your application using a DynamicEntityLayer. The API is flexible, allowing you to manage the connection and process data from any data feed required by your application. Use the custom DynamicEntityDataSource to connect to a variety of feed types from streaming feeds over a socket to data files that are updated over time.

Specify fields when connecting to an ArcGIS stream service

This release includes the ability to specify a subset of fields from an ArcGIS stream service using ArcGISStreamServiceFilter::outFields.

Support for camera controller, viewshed, and line of sight on a dynamic entity observation

In addition to a DynamicEntity, you can now use a DynamicEntityObservation as the input to a GeoElementViewshed, GeoElementLineOfSight, and OrbitGeoElementCameraController.

Performance improvements

Several performance improvements have been made to dynamic entities in this release. DynamicEntityObservation attribute information is now compressed down to 25% of previous sizes, and observational parsing has been increased by up to a factor of four, allowing for higher throughput.

Visualization

Support for clustering of point features

With this release, ArcGIS Maps SDK for Native Apps adds support for feature clustering. Point features in a feature layer can be clustered in a map when displayed using dynamic rendering mode.

Clustering

Feature clustering dynamically aggregates groups of points that are within proximity of each other so they can be represented with a single symbol. The size of the symbol indicates the relative number of points it represents. Clusters are updated as the map scale and extent changes, allowing you to see patterns in the data that may otherwise be difficult to visualize with a large number of overlapping points. You can use ArcGIS Pro or ArcGIS Online to author and publish point feature layers enabled with clustering.

Adding a cluster-enabled feature layer to your Maps SDK app, or opening a web map that contains one, will render clusters if the layer's rendering mode is dynamic. If the rendering mode is set to static, individual features in the layer are drawn using the layer's renderer.

Here are some details about working with clustering in ArcGIS Maps SDK for Native Apps:

  • A layer's renderer is separate from its cluster renderer. If a cluster renderer was not defined when authoring the data, the layer's renderer is used to infer cluster symbology.

  • If the rendering mode is set to static, individual features are drawn using the layer's renderer. This is the same appearance the layer would have if clustering was not enabled.

  • Point features that are not included in a cluster are drawn as individual features using the layer's renderer.

  • Clusters are dynamically updated as the map's scale and extent changes.

  • Identifying a clustered geoelement returns an AggregateGeoElement. The geometry of an aggregate geoelement is the centroid of the cluster graphic and its attributes are the summary fields defined at the time of authoring or publishing the layer.

  • Pop-ups on clusters are separate from the pop-ups defined on a feature layer. When you identify an aggregated geoelement, you can get access to pop-ups defined on the clusters.

  • You can toggle the visibility of clusters. When clusters visibility is turned off, the individual features are drawn.

  • Clustering does not apply to layers with polyline and polygon geometries and is not supported in 3D.

Here are a few known issues with clustering in this release:

  • Clusters do not display labels.

  • Cluster graphics cannot be selected or highlighted.

  • Pop-up expressions that use the $aggregatedFeature variable are not evaluated.

  • If the authored cluster symbology contains size visual variables on a summary field other than cluster_count, the cluster symbols do not display with the correct sizes.

Geometry

Programmatically move, rotate, and scale geometry

The GeometryEngine class introduces new static methods to move, rotate, or scale geometries.

Interactively rotate and scale geometry

The GeometryEditor now displays control graphics when appropriate geometry editor elements are selected. These graphics allow the user to interactively rotate and apply uniform or free-stretch scaling to the selected elements.

Create predefined shapes

The new ShapeTool, for use with the GeometryEditor, allows you to create a predefined shape, such as ellipse, triangle, rectangle, and arrow. These shapes can be represented using polyline or polygon geometry.

Utility network

Utility Network offline tracing enhancements

Offline tracing support was added to the Native SDKs 200.1 release and has been improved in 200.2 with additional bug fixes and tracing support.

  • The ArcGIS Maps SDKs for Native Apps now support tracing of utility networks taken offline from an ArcGIS Enterprise 11.1 feature service.
  • Offline traces now support nearest neighbor trace results and loops tracing.
  • Offline traces have an improved performance when tracing with propagators. These new tracing enhancements are available for all mobile geodatabase types.

SubtypeSublayer feature templates

Custom feature templates can be configured for each FeatureSubtype in a Subtype Group Layer using ArcGIS Pro, and the ArcGIS Native Maps SDKs now provide these templates via the SubtypeSublayer::featureTemplates property.

Arcade

Support for Arcade 1.23

ArcGIS Maps SDKs for Native Apps now support Arcade V1.23. Enhancements include the following:

  • Support for new geometry functions NearestCoordinate and NearestVertex.

  • Support for binary and octal number literals.

  • Updates to Feature and Dictionary functions. These functions now accept more types, easing conversions between features, dictionaries, and geometries.

  • Reduction of preparation time by half when a script is evaluated. This reduction is most significant in multiple evaluations of a small script, for instance a script calculating a value from a few feature attributes.

The newly added GetEnvironment function has limited support: locale and application values always return empty strings.

SDK Enhancements

Metal rendering for iOS and macOS

Metal is now the default rendering API for iOS and macOS. While OpenGL is still supported, Metal is the rendering API of choice for Apple, and offers improved performance and support. Note that shader files must now be deployed with apps. Further details and requirements are available in the System Requirements and Deployments topics.

Direct3D rendering for Windows

Direct3D is now the default rendering API for Windows. While OpenGL is still supported, Direct3D is the rendering API of choice for Windows, and offers improved performance and support. Note that shader files must now be deployed with apps. Further details and requirements are available in the System Requirements and Deployments topics.

QFuture asynchronous methods

Asynchronous "tasks" that return a TaskWatcher now have a new variation of the method to make working with asynchronous code easier. The new methods contain the suffix Async, for example RouteTask::solveRouteAsync(), and will return a QFuture. QFutures offer many benefits, including more centralized and concise code, chaining tasks together with .then(), and improved error handling. The TaskWatcher-based methods will be deprecated in an upcoming release, in favor of the QFuture-based methods. All new APIs will use only QFuture-based async tasks.

Qt 6.5.1

The minimum version of Qt is now 6.5.1. Qt 6.5 brings in numerous improvements, such as improved styling and theming. Along with the Qt upgrade, there are several compiler and OS updates, which are highlighted in the System Requirements.

Permissions API in AR Toolkit on Android

AR Toolkit uses the new Qt Permissions APIs for requesting Camera access.

Local Server

ArcGIS Maps SDK for Local Server 200.1 is an incremental compatibility release that provides support for geoprocessing and map packages created with ArcGIS Pro 3.x.

You can use ArcGIS Maps SDK 200.2 for Qt with ArcGIS Maps SDK for Local Server 200.1 or ArcGIS Runtime Local Server SDK 100.15. By default, the Qt Maps SDK version 200.2 will use Local Server SDK version 200.1. You can use an alternative version by setting the install path. For example, the code below will tell the API to use the developer installation of the Local Server SDK version 100.15:

Use dark colors for code blocksCopy
1
LocalServer::setInstallPath("c:/Program Files/ArcGIS SDKs/LocalServer100.15");

When deploying your application, ensure your Local Server deployment directory is included at the location specified by the install path property. For more information see the Deploy Local Server guide topic.

Breaking API changes

  • Due to Qt 6.5 and Xcode updates, bitcode is no longer supported on iOS.
  • Projection Engine compatibility: The internal directory structure of the Projection Engine data files has changed. The new file structure within the Projection Engine data files version 200.2 is supported with ArcGIS Maps SDK for Native Apps version 200.1 or later. If your application deployment includes the Projection Engine data files, you may need to update your build or setup process to reflect this change.

Behavior changes

  • GeometryEditor.symmetricDifference now supports curves.
  • Projection engine (PE) data for geographic transformations are arranged in a different file structure than previous releases. This change is designed to accommodate the increasing number, complexity, and size of the data files. See the readme in the projection engine data download for more information.
  • LabelDefinition::setWhereClause() sql can now include N for literal unicode text.

Deprecations

API deprecations

  • QML API is deprecated. ArcGIS Maps SDK for Qt comprises two different APIs: QML API and C++ API. The QML API offers a "pure QML" experience, where no C++ code is written, and everything is written with QML and JavaScript code. This was convenient and allowed for rapid prototyping but had several drawbacks and limitations to the APIs and functionality delivered. The C++ API allows apps to be written with either a QML UI or Qt Widgets UI (for desktop apps), both using the same C++ backend code. The C++ API is more flexible, faster, and follows the best practice patterns promoted by Qt Group. Developers will find that the C++ API offers the best scenario: building responsive UIs with QML and leveraging the full power of Qt with the backend C++ APIs available directly through the Qt Framework. Version 200.4 of ArcGIS Maps SDK for Qt is the last release to include QML API. Apps should begin migrating to the C++ API.

  • ArcGIS Extras API is deprecated. This announcement follows the QML API deprecation. This helper library augmented QML shortcomings by exposing Qt functionality that was only available in C++ to QML. 200.4 is the last release to include ArcGIS Extras. Apps should begin migrating to the Qt C++ API.

OS and framework deprecations

  • Support for Windows 10 Enterprise LTSC Version 1809 (Build 17763) and Windows Server 2019 Standard and Datacenter is deprecated. Version 200.2 is the last release to support these versions. A minimum of Windows 10 Enterprise LTSC Version 21H2 (Build 19044) and Windows Server 2022 Standard and Datacenter will be required at the next release.
  • Support for iOS/iPadOS 14 is deprecated. The last release to support this version is 200.2. A minimum of iOS/iPadOS 15 will be required at the next release.

Issues resolved

Issues addressed in this release are listed below.

  • BUG-000148628: After tilting scene towards the zenith, it is not possible to tilt it back towards the earth's surface.

  • BUG-000149324 Fixed an issue where pop-ups did not load when certain fields are hidden before publishing.

  • BUG-000152125: Changing the visibility of GroupLayer layers for map image layers does not trigger the layer viewer state change handler on a MapView object.

  • BUG-000155877: The nested feature group layer stored in a mobile map package (.mmpk) shows inconsistent visibility when the group feature layer's toggle button in the layer list is switched on or off.

  • BUG-000157495: Fixed an issue where new attachments may not be submitted for features to a feature service layer when the service contains a second layer without a global ID field.

  • BUG-000158130: Fixed the value reported by the scaleSymbols property of SubtypeFeatureLayer.

  • BUG-000158132: Fixed an issue where cloning a SubtypeFeatureLayer did not retain the scaleSymbols properties of sublayers.

  • The 3rd-party Libtiff library has been upgraded to 4.5.1.

  • Fixed a bug where an utility network that is configured with the "only include simple features" option could not be loaded from an ahead-of-time offline map.

  • Fixed a bug that did not preserve the rendering or pop-up configuration for a SubtypeFeatureLayer when taken offline in some scenarios.

  • Improved performance and decreased memory usage when reading mobile map packages, webmaps, and webscenes.

  • Fixed a bug that cleared attributes of a child feature in a simple relationship when its parent feature was deleted.

Known issues

Known issues or limitations for this release are listed below.

  • BUG-000160506: Using GeometryEditor to transform a geometry that has a different spatial reference than that of the associated map view can appear to distort the geometry. A workaround for this bug is to first project the geometry to the spatial reference of the map view and then pass it to the GeometryEditor.
