Feature services

With the 10.6.1 release, feature services have added support for the having clause and distinct-count query operations, along with added resources for layer-based metadata. These enhancements are for both enterprise geodatabase-based feature services and hosted feature services.

Feature services published to an ArcGIS Enterprise federated server with data stored in a registered enterprise geodatabase:

• Service Apply Edits includes support for split operations.
• Feature services can now be published with unique value symbology using multiple fields, proportional symbols symbology, and with symbology using ArcGIS Arcade expressions.

Hosted feature services in ArcGIS Enterprise:

• Added support for layer level truncate operation.
• Hosted feature services stored in a spatiotemporal big data store now have support for adding fields.

All types of feature services now support the quantizationParameters parameter when using layer query parameters returnCentroid , returnExceededLimitFeatures, and resultType. At ArcGIS Enterprise 10.6, coordinate quantization was only supported for hosted feature services and was disabled by default. This is now enabled by default and available for all types of feature services. Developers can check for this support via the supportsCoordinateQuantization property.

New layer properties added including supportsHavingClause, supportsCountDistinct, supportsCoordinatesQuantization, supportsReturningGeometryCentroid, supportsQueryWithResultType, geometryField, standardMaxRecordCount, tileMaxRecordCount, maxRecordCountFactor, and hasMetadata.

New service properties added including advancedEditingCapabilities and extractChangesCapabilities.

GeoAnalytics Tools

Three GeoAnalytics Tools are new at 10.6:

• Calculate Field calculates values on a new or existing field, and creates a new layer in your portal.
• Detect Incidents examines time-sequential values using a specified condition, marks features meeting that condition as incidents, and appends additional fields to those features detailing the incident.
• Geocode Locations from Table provides a convenient tool to geocode large tables of addresses into points. Its output is a feature layer in your portal.

Enhancements have been made to existing tools:

• Two new temporal relationships, Near Before and Near After, are available in Join Features.
• An option to summarize all features into a single feature has been added in Summarize Attributes.
• A Distance Split can now be applied to a track in Reconstruct Tracks.

Raster Analytics tasks

Eleven new Raster Analytics tasks are available at 10.6, in three different functional areas.

JSON content type
