Class: ArcGISTiledMapServiceLayer
[ AMD Module Require | Legacy Module Require ]
require(["esri/layers/ArcGISTiledMapServiceLayer"], function(ArcGISTiledMapServiceLayer) { /* code goes here */ });
Description
(Added at v1.0)
Allows you to work with a cached map service resource exposed by the ArcGIS Server REST API. A cached service accesses tiles from a cache instead of dynamically rendering images. For dynamic map services, see DynamicMapServiceLayer. For additional information on working with map service attribution please visit the official attribution in your app documentation.Samples

Constructor Details
Creates a new ArcGISTiledMapServiceLayer object. A URL is a required parameter. This layer also takes some optional parameters. These optional parameters can be included in any order.
Parameters:
< |
Required | URL to the ArcGIS Server REST resource at represents a map service. An example is http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Portland/Portland_ESRI_LandBase_AGO/MapServer. For more information on constructing a URL, see The Services Directory and the REST API. |
< |
Optional | Optional parameters. See options list. |
options properties: < |
Optional | Class attribute to set for the layer's node. |
< |
Optional | Lists which levels to draw. In the following example, assume you have two layers. The first layer is an ArcGIS Online Street Map layer, and you want to use only levels 0 through 7. You also have a second layer with more recent street data that you want to use for levels 8 through 12.
require([
"esri/map", "esri/layers/ArcGISTiledMapServiceLayer", ...
], function(Map, ArcGISTiledMapServiceLayer, ... ) {
var map = new Map( ... );
var agoServiceURL = "http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer";
var agoLayer = new ArcGISTiledMapServiceLayer(agoServiceURL, { displayLevels:[0,1,2,3,4,5,6,7]});
map.addLayer(agoLayer);
...
});
require([
"esri/map", "esri/layers/ArcGISTiledMapServiceLayer", ...
], function(Map, ArcGISTiledMapServiceLayer, ... ) {
var map = new Map( ... );
var myServiceURL = "http://myserver/ArcGIS/rest/services/myservice/MapServer";
var myLayer = new ArcGISTiledMapServiceLayer(myServiceURL, { displayLevels:[8,9,10,11,12]});
map.addLayer(myLayer);
...
});
|
< |
Optional | An array of objects that define areas where a tiled map service should not display tiles. Each exclusion area object has the following properties:
min/maxZoom take precedence over min/maxScale. The value for geometry is of type Extent. Other geometry types might be supported in the future but are not currently supported. Geometry must be in the same spatial reference as the map. The exception is that a geographic extent (WGS84) can be used with web mercator maps and vice versa. Example:
var exclusionAreas = [{
minScale: 40000,
maxScale: 9028,
geometry: new Extent(
13871520.850500003,
3910293.086000003,
14574034.873400003,
4686306.161399998,
new SpatialReference(102100)
)
}];
|
< |
Optional | Id to assign to the layer. If not assigned, esri.Map assigns value. |
< |
Optional | infoTemplates object. See the infoTemplates property for details. |
< |
Optional | Initial opacity or transparency of layer. Values range from 0.0 to 1.0, where 0.0 is 100% transparent and 1.0 has no transparency. The default value is 1.0. |
< |
Optional | Refresh interval of the layer in minutes. Non-zero value sets up automatic layer refresh at the specified interval. |
< |
Optional | The purpose of resampling is to enlarge the image and fill in at the levels where there are no tiles available. When true, tile resampling is enabled. The default value is true for Esri's basemaps. For other services, it is initially undefined until the layer loads, then defaults to the value in the resourceInfo, or false if not specified in the resourceInfo. Prior to version 3.12, the default was false.
By specifying this option, it does not necessarily mean resampling to any scale will work. For example, a tiled map layer may not have data beyond level 15 in some areas (for example rural areas). But in other areas (for example metropolitan areas), it may have data down to level 19. Enabling resampling would draw images all over to the last level and deliver a consistent user experience. In areas with no data, blurred images display.
The tiled services need to return a 404 for missing tiles to get this option to work. Note that 404s for missing tiles did not become the default for ArcGIS Server until 10.2. Added at 3.6, updated at 3.12 |
< |
Optional | Number of levels beyond the last level where tiles are available. If not specified, resampling is enabled at all levels where tiles are not available. The tiled services need to return a 404 for missing tiles to get this option to work. Note that 404s for missing tiles did not become the default for ArcGIS Server until 10.2. Added at 3.6. |
< |
Optional | Specify the metadata of the layer. |
< |
Optional | When true, the layer's attribution is displayed on the map. The default value is true. Added at v3.1
require([
"esri/layers/ArcGISTiledMapServiceLayer", ...
], function(ArcGISTiledMapServiceLayer, ... ) {
var basemap = new ArcGISTiledMapServiceLayer(layerUrl, {
showAttribution: false
});
...
});
|
< |
Optional | Array of REST endpoints that can be used to retrieve tile images. At version 2.7, layers hosted on ArcGIS Online will automatically use server.arcgisonline and services.arcgisonline.com as the tile servers. |
< |
Optional | Initial visibility of the layer. The default value is true. |
Sample:
require([
"esri/layers/ArcGISTiledMapServiceLayer", ...

Event Details
[ On Style Events | Connect Style Event ]
Fires when there is a problem retrieving a layer. Should be used in favor of onError. (Added at v3.5)
Event Object Properties:
< |
ArcGIS Server error message returned in a JavaScript error object. |
Fires after layer properties for the layer are successfully populated. This event must be successful before the layer can be added to the map. Should be used in favor of onLoad. (Added at v3.5)
Event Object Properties:
< |
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 the layer opacity (transparency) changes. A number property named opacity that indicates the new opacity. Values range from 0.0 to 1.0, where 0.0 is 100% transparent and 1.0 has no transparency. |
This event is fired when the layer's
refreshInterval is modified. (Added at v3.7)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. (Added at v3.6)
Fires any time a layer has finished loading or updating itself.
For an ArcGISTiledMapServiceLayer,
the event fires when all required tiles have been retrieved and displayed. For an
ArcGISDynamicMapServiceLayer or
ArcGISImageServiceLayer, the event fires
when the map image has been retrieved and displayed. For a GraphicsLayer,
the event fires when all graphics have been redrawn after a pan or zoom.
Deprecated at v2.0. Use update-start and update-end instead. (Added at v3.6)
Fires when a layer has finished updating its content. It is the responsibility of the subclass to determine when this event is fired. Should be used in favor of onUpdateEnd. (Added at v3.5)
Event Object Properties:
< |
Optional argument. The error object is available when an error occurs during the update. |
Fires when a layer begins to update its content. It is the responsibility of the subclass to determine when this event is fired. Should be used in favor of onUpdateStart. (Added at v3.5)
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. |
