DataSourceOptions interface

Package:

azure-maps-control

A data source for managing shape data that will be displayed on the map. A data source must be added to a layer before it is visible on the map. Options for a DataSourceOptions.

Properties

buffer	The size of the buffer around each tile. A buffer value of 0 will provide better performance but will be more likely to generate artifacts when rendering. Larger buffers will produce left artifacts but will result in slower performance. default 128
cluster	A boolean indicating if Point features in the source should be clustered or not. If set to true, points will be clustered together into groups by radius. default false
clusterMaxZoom	The maximum zoom level in which to cluster points. Defaults to one zoom less than maxZoom so that last zoom features are not clustered.
clusterMinPoints	Minimum number of points necessary to form a cluster if clustering is enabled.
clusterProperties	Defines custom properties that are calculated using expressions against all the points within each cluster and added to the properties of each cluster point.
clusterRadius	The radius of each cluster in pixels. default 50
filter	An expression for filtering features prior to processing them for rendering.
generateId	Whether to generate ids for the geojson features. When enabled, the feature.id property will be auto assigned based on its index in the features array, over-writing any previous values.
lineMetrics	Specifies whether to calculate line distance metrics. This is required for line layers that specify lineGradient values. default false
maxZoom	Maximum zoom level at which to create vector tiles (higher means greater detail at high zoom levels). default 18
promoteId	A property to use as a feature id (for feature state). Either a property name, or an object of the form {: }.
tolerance	The Douglas-Peucker simplification tolerance that is applied to the data when rendering (higher means simpler geometries and faster performance). default 0.375
