December 2011: Updated Layer IDs
If you use the GIS Hub's Web Map Services (WMS) and/or Web Coverage Services (WCS) with the "All_Imagery" or "All_Elevation" data services, the layer IDs have changed again!
Back in May 2011 we provided some background information on why these IDs have changed from time to time. With some recent updates to ArcGIS Server we can now go back to using static layer IDs.
If you use the WMS and/or WCS for these two services please visit the REST All_Elevation page and/or the All_Imagery REST page and scroll to the bottom of the page where you can click on the WMS and WCS links to obtain the new layer ID names.
