Line labeling improvements

At this release, labels on line features are kept in the visible extent when possible. This behavior is automatic (no additional API calls are required) unless repetition is being used along the line. If repetition is used then it is assumed that the author is deliberately controlling the approximate frequency of labels on the map in order to avoid clutter.

Line labels will also make more small local movements to avoid obstacle features or other labels. This applies to labels that use repetition and those that don't. For labels with repetition, this may affect the distance between repetitions.


Support for text symbol flip angle

ArcGIS Runtime now honors flip angle on a CIMTextSymbol. The flip angle property defines the angle at which rotated text is flipped (mirrored) in place. The property gets applied dynamically at rendering time and is not exposed via a public API. Angle is calculated in degrees from vertical. There are four different ways rotation can be applied to a symbol: map rotation, symbol rotation, geometry rotation, and marker rotation (defined on the respective symbol layer). Flip angle is not honored in 3D or if the text symbol's angle property is greater than 0.

Utility Network

Prevent subnetwork controller deletion

The utility network allows designating specific features as subnetwork controllers. Subnetwork controller features serve as network sources or sinks and form the starting points of a subnetwork. After a device or junction object has been assigned as a subnetwork controller, the feature cannot be deleted. Beginning with version 100.15, when attempting to delete a feature that is a subnetwork controller, ArcGIS Runtime will prevent its deletion.


Geotriggers are now floor-aware

Geotriggers that use floor-aware feature data can now make use of the level information provided by a floor-aware LocationDataSource (such as the IndoorsLocationDataSource ) to limit notifications to fences on the correct floor. For example, notifications will only be sent when you enter/exit a fence based on a feature that is on the same floor as your current Location . If the location does not include floor information then the floor attribute of a fence is ignored.

Indoor positioning

Support for large positioning files

In previous releases, the IndoorsLocationDataSource did not always work effectively on all platforms when using large positioning files (30 MB or more). With release 100.15, the indoor location data source can use positioning files up to 300 MB.

Improved indoor position accuracy

This release includes several improvements to indoor positioning system (IPS) accuracy.

  • Indoor positioning output that does not use path snapping is now more stable. The display presents fewer horizontal/sideways jumps and drifts and follows the user's actual position more precisely.
  • Positioning accuracy has been improved when the location data source switches between GNSS and IPS.
  • Floor level estimation is now more accurate.

Improved output

  • IndoorsLocationDataSource will no longer send warnings that are not relevant to the diagnosis of indoor location data source issues.
  • The timestamps for indoor location data source positioning output are now correct for estimated positions. IndoorsLocationDataSource will no longer output the last known position when a position cannot be estimated.


Arcade improvements

At this release, ArcGIS Runtime supports Arcade 1.19, which has the following enhancements.

  • Support for while loops like the one shown below.
Use dark colors for code blocksCopy
var count = 1
while (count < 10){
  count *= 2
  • Simplified Dictionary construction where the name of an entry is the same as the variable containing the value.
Use dark colors for code blocksCopy
var hello = "Hello"
var name = "Arcade"
{hello, name} // Equivalent to {"hello":hello, "name":name}
  • A new ConvexHull function added to the set of geometry functions.
  • The FeatureSet constructor can now accept a dictionary.

For more information, see the Arcade documentation.

Enhanced support for attribute rules

ArcGIS Runtime 100.15 adds support for the following Arcade data functions for use with attribute rules:

  • GetFeatureSetInfo() returns metadata for the original source database and service (if applicable) of a feature set. This function was added in Arcade version 1.18.

  • NextSequenceValue() returns the next sequence value from the database sequence specified. This function executes locally when called from attribute rules running in stand-alone mobile geodatabases.


Utility Network Trace Toolkit Component

The Utility Network Trace Tool allows you to easily run a trace for any map that has been authored with trace configurations. To use the tool, select a trace configuration and click on the map to add a starting point. Run the trace, and the results will be displayed in the UI and on the map. This is supported in WPF, UWP, and Xamarin Forms.

Projection engine updates

The following changes have been made to coordinate systems, map projections, and geographic transformations:

  • Several planetary satellites and extraterrestrial bodies had updated definitions added based on the IAU/IAG 2015 publication. Projected coordinate systems for Mars and the moon were also added.

  • The Luxembourg 1930 name was updated to LUREF which affected geographic and projected coordinate systems and several transformations.

  • Several edits were made to geographic transformations:

    • The name of MGI_1901_To_WGS_1984_12, 8688, was updated to MGI_1901_To_WGS_1984_16.
    • The rotation values were fixed in 9383, KSA-GRF17_To_WGS_1984_1, and 9472, DGN95_to_SRGI2013_1.
    • The transformation method was fixed in 1825, Hong_Kong_1980_To_WGS_1984_1.
    • The WKIDs and transformation methods were updated for CR05_to_CR-SIRGAS_1 and CR05_To_WGS_1984_2.
    • A rotation value was fixed in 8827, Camacupa_2015_To_RSAO13_1.
  • Many years ago, the EPSG registry ( deleted entries that had problems. They added corrected entries with new well-known IDs (WKID). This included a large group of geographic transformations where the ‘old’ WKIDs were in the 8xxx range. Esri kept the previous WKIDs in case someone was using them, but ‘code-changed’ the objects to use the official WKIDs. EPSG has started reusing the 8xxx numbers, although only a few objects so far have been affected. The code-change entries that used 8xxx (and which no longer exist in the EPSG registry) were removed at this release. This allows us to use the 8xxx values for new EPSG entries. Five GDA2020 transformations were affected and had been given Esri WKID numbers (108xxx). They now have code-change entries to their official EPSG WKID numbers. These are:

    • GDA_1994_To_GDA2020_1, 108060 to 8048
    • GDA_1994_To_GDA2020_NTv2_2_Conformal_and_Distortion, 108447 to 8447
    • GDA_1994_To_GDA2020_NTv2_3_Conformal, 108446 to 8446
    • GDA_1994_To_GDA2020_NTv2_4_Christmas, 108444 to 8444
    • GDA_1994_To_GDA2020_NTv2_5_Cocos_Keeling, 108445 to 8445
  • Several new vertical transformations based on geoids, quasi-geoids, or other conversion grids are available. You can use them to transform to or between gravity-related vertical coordinate systems for the following areas: Belgium, Estonia (geoid file distributed by AlphaGIS, Estonian distributor), Italy (EVRF 2019), Latvia, Lithuania, Switzerland, Tasmania (Australia), Ukraine (EVRF 2019), and United Kingdom (HS2-VRF).

  • Projection mathematics for the Hotine oblique Mercator projection and the Rectified skew orthomorphic projection have been modified to fix an issue with ±90° azimuth cases. This is expected to cause about 4 cm offset in the center of the Swiss projected coordinate systems (affected WKIDs are: 2056, 21780, 21781 and 21782). The projection algorithm has been added as a new variant to the Hotine oblique Mercator projection.

Support for iOS 16

Shortly after iOS 16 was announced during Apple's WWDC conference in June 2022, testing began on the developer and public betas to ensure apps built with ArcGIS Runtime could adopt it quickly. Following the official release of iOS 16 on September 12, 2022, ArcGIS Runtime 100.15 was certified to support iOS 16.

Local Server

ArcGIS Runtime Local Server SDK 100.15 is an incremental compatibility release that provides support for geoprocessing and map packages created with ArcGIS Pro 2.9.x. This release supports the ArcGIS toolbox format (.atbx file extension), which represents the next generation of geoprocessing toolbox, tool, script, and model storage. Using ArcGIS Pro, you can create toolsets, add new model and script tools, change properties, and copy tools from legacy toolboxes (.tbx file) into the new toolbox format. For more information see Create a toolbox.

Breaking API changes

There are no breaking changes with this release.

Behavior changes

  • Layers imported from ArcGIS Pro 3.0 that specify labels be offset to the Left or the Right of a line feature (following its digitization direction), will now have that positioning respected rather than defaulting to Above and Below the line feature on the screen.
  • Horizontal labels offset from a line feature are now positioned so that their closest point is at the expected offset from the line feature. This was not previously correct in all cases, especially when the map was rotated.
  • Labels are no longer lost when elevation changes.


API deprecations

There are no API deprecations with this release.

OS and framework deprecations

  • Support for .NET Framework 4.6.1 is deprecated. The last release to support .NET Framework 4.6.1 will be version 100.15. A minimum of .NET Framework 4.7.2 will be required at the next release.
