Identify on different projection tile layer

ManuelFrias — Wed, 18 Aug 2010 11:07:19 GMT

Hello,

All layers in my service are in spatial reference 3035, including the base map tile layer. The identify tool works fine. If I try the World_Street_Map from arcgisonline the identify doesn't work. It doesn't return anything.

I thought it might be a problem with the projection (World_Street_Map is in 102100) but isn't it so that my dynamic layers get reprojected on the fly? Is there anything I am missing?

Thanks,
Manolo

Manolo,

   If you go to the REST service page for that map service

http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer

You will notice that it does not support identify

Supported Operations:   Export Map   Generate KML

Ones that support identify will have

Supported Operations:   Export Map   Identify   Generate KML

Hi Robert,

sorry, I didn't explain myself clearly. I don't want to identify the World_Street_Map I want to identify my own dynamic layers.

When I have my background tile layers I can identify my dynamic layers. They are both in the same projection. When I switch to World_Street_Map I can not.

The first thing it came to my mind is that the spatial reference is different.

Manolo,

I would agree that it is a spatial reference issue. Have you tried to set the IdentifyParameters spatial reference?

Thanks a lot Robert!

setting the spatial reference did it!
