Merge feature properties

ShowAssets

Comma-separated list of shown asset names.

Outputs a list of asset names visible in current extent separated by comma (,). Only layers with property merge equal to true are taken into consideration.

AssetNameTemplate

String template used to merge Features.

Template to use when merging properties coming from Features widget property. Templates are string literals where the property names between curly brackets ({propertyName}) are replaced with the value of that property.

Features

List of features to be merged with the layers marked with the layer property merge equal to true. The merged is done by matching the asset names in the layer (using the assetNameTemplate layer property) and the asset names for the features (items) passed in this widget property (using the AssetNameTemplate widget property).

Using this property it's possible to modify or extend the properties of the matching features, for example, when there are assets in a layer coming from a GIS server with properties that are mostly static, and some other related data exists on another data source (real-time sensor values, alarms, transactional information in a database, etc.).

After the properties are merged, it's possible to use the new information to change how the feature (or asset) is rendered on the map, for example, by changing the position of a moving asset, or changing the marker color depending on an alarm status.
