Class: VectorTileLayer
dojo.require("esri/layers/VectorTileLayer");
Description
(Added at v3.15)
A VectorTileLayer renders cached tiles of data. It is similar to a WebTiledLayer in that it renders cached data; however, a WebTiledLayer renders as a series of images, not vector data.
Unlike image caches, vector tiles contain data for rendering the tile information. Because the data in VectorTileLayer is vector, it is stored in individual layers containing geometry, attributes, and styles. Styling information is stored separately from the tile geometry and attributes, and more than one style can be defined. This means that one set of vector tiles may be styled numerous ways without having to generate a new cache for each style. This saves space and speeds up the process for creating new map styles.
Styles may contain multiple options for rendering the same type of feature. In a street layer, for example, major highways might have three symbology options. Styles can also be changed on the client without having to make a request for a new tile from the server. This enables maps to be dynamic on the client while still taking advantage of cached vector data.
For more information about vector tile layers see the Vector tile layer topic in the ArcGIS Online Help and the Vector Basemaps group in ArcGIS Online.
Known Limitations:
- Vector tile layers can be displayed in Internet Explorer 11 and higher and most other current versions of desktop browsers, including Chrome, Firefox, and Safari.
- Vector tile layers have the best performance on machines with newer hardware.
- In some cases, labels along vector tile boundaries may collide with labels from the neighboring tile.
- VectorTileLayer printing requires ArcGIS Server 10.5.1 or later. Using ArcGIS Server 10.5.1, the PrintTask will create a client-side image for the VectorTileLayer in the printout. For printing secure VectorTileLayers with ArcGIS Server 10.5.1 or 10.6.0, the PrintTask will also create a client-side image for the VectorTileLayer in the printout. This has some limitations related to large size printing quality and a dependency on browser window height/width ratio.

The loaded layer. |
Fires when the layer opacity has been changed, and returns an object with the opacity value. Should be used in favor of onOpacityChange. (Added at v3.5)
Event Object Properties:

Fires when a layer's minScale and/or maxScale is changed. Should be used in favor of onScaleRangeChange. (Added at v3.5)
Fires when a layer's scale visibility changes. The scale visibility changes when a layer is initially visible and becomes invisible because the map scale does not intersect the layer's scale range or vice versa. Should be used in favor of onScaleVisibilityChange. (Added at v3.5)
Fires when the style is changed on the layer.
Event Object Properties:
< |
The style object of the service with fully qualified URLs for glyphs and sprite. |
Sample:
require([
"esri/layers/VectorTileLayer", ...
], function(VectorTileLayer, ... ) {
var vectorTileLayer = new VectorTileLayer("https://basemaps.arcgis.com/arcgis/rest/services/World_Basemap/VectorTileServer");
vectorTileLayer.on("style-change", function(event){
console.log("Event: ", event);
});
...
});
Fires when the layer has finished updating its content. This event is always preceded by update-start. (Added at v3.21)
Event Object Properties:
< |
Optional argument. The error object is available when an error occurs during the update. |
Fires when the layer visibility has been changed, and returns an object with a Boolean visible property containing the new visibility value of the layer. Should be used in favor of onVisibilityChange. (Added at v3.5)
Event Object Properties:
< |
Fires when the layer visibility changes. A boolean property named visible indicates whether or not the layer is visible after visibility changed. |
