Get Layer Description From Sublayer

JordanParfitt — Tue, 17 Jul 2012 20:16:55 GMT

I'm trying to display meta data on sub layers. My plan was to pull it through the API from the Description field. For example "CRS 35-1-105(c) I �?? IV" in the below service:

http://165.127.200.27/OITGISDevelopment/rest/services/GovRegions/GovRegions_CDA/MapServer/1

I'm looking for it in the API and don't see it anywhere. Is there a way to get it from the layerInfos object under the ArcGISTiledMapService object?

Thanks in advance!

Jordan,

Just make a call to the layers rest interface and ask it to be returned as JSON i.e.

http://165.127.200.27/OITGISDevelopment/rest/services/GovRegions/GovRegions_CDA/MapServer/1?f=json&pretty=true

You should then be able to create an object from the response and then find the relevant field you are after

Regards

Anthony

You can also use the LayerDetails class.

See:

Is this only available if I bring it in as a feature layer? If I do it as dynamic or tiled I can't get to it right? All I see is layerInfos which only contains the name of the sublayer but no definition.

You can get LayerDetails in many different ways. See the "See also" links at the top of the AS Doc for LayerDetails.
