FeatureCollection

Definition

A FeatureCollection groups one or more map features together. Any events that occur on a feature in the collection will also trigger the corresponding event in the collection component. FeatureCollections can be loaded from external resources to populate Maps with content. GeoJSON is the only format supported at this time.

HeightPercent

Specifies the FeatureCollection’s vertical height as a percentage of the Screen’s Height.

Source

Width

Specifies the horizontal width of the FeatureCollection, measured in pixels.
