I have two services ArcGISTiledMapServiceLayer; a service country and services province; service country cached at scale 1000000 to 15000000; services province cached at scale 2000 to 1000000, how to when i zoom map at scale 5000000, then services province overlay service country. (i cannot cache service country at scale(2000 to 15000000) because the number of tile images too much and too long time, and my server does not allow this.). thank you so much!!
You could try using group layers with scale dependencies in ArcMap.
Create 2 group layers. Put your country data in one, and the province data in the other. Then set the scales you want the data to show on the group layer.
Hope this helps!
You can have the two different tiled services with different Levels of Detail (LOD) on the same map. Take a look at this sample showing this.
