Javascript Map Layer Type

JimBridge

I have a map with an unknown number of feature layers and raster layers. I need to be able to identify if a layer is a raster layer or a feature layer. I can't seem to find any where this is exposed. I tried looking in the map.getLayer("baseLayer").layerInfos collection but it doesn't have the type. In the Silverlight API I found this information when the legened was refreshed by checking the layerType field in the layeritems . I can't seem to find anything similar in the javascript api.

Thanks

Jim

Take a look at this sample that shows how to get information about a specific layer. While the sample only shows the fields, open up the browser's console to see all the information available (including type) about that layer.

That will do exactly what I need.

Thanks for the help!

Ken ,

Thanks for the response. I'm not sure if I can get what I want from that, although it could just be me.

I can see that the map.getLayer("baseLayer") Is a dynamic layer using that but I want to see if the map layer listed in layerinfo is of type raster. I can't seem to get to that maybe I'm not hitting the sublayer. My base layer is a esri.layers.ArcGISDynamicMapServiceLayer tied to a rest service for a map that has multiple layers. If I look at the service directly and choose a layer I see :

Layer: Aerial (10)

Name: Aerial

Display Field:

Type: Raster Layer

Geometry Type: null

Description:

Definition Expression:

Copyright Text:

Default Visibility: true

MaxRecordCount: 0

Supported Query Formats: JSON, AMF

I may just be missing something but I can't seem to get something that tells me that this layer is raster?

Thanks

Jim

You can use declaredClass property of the layer. Take a look at this discussion.
