Hello. Is it possible to set the zoom level in the config file to be able to zoom in a lot closer with the base maps. I have developed a few web applications for our water and sewer inspectors. And one issue that we are having is that at some intersections there are multiple valves and you need to be zoomed in pretty close to be able to see how all valves are placed on the water lines. So I guess my question is. I sit possible to overwrite the zoom level in the esri base maps. and if so How do I do that. Thanks in advance with any help with this.

Hi,
in a flexviewer app, i use a cached mapservice from 1:6.000.000 to 1:2.000 scales as basemap.
My users need to zoom at scales 1:1000, 1:500.

As 1:2000 is the max resolution of the photo i don't want to cache it at highter scales.

I don't wan't to display the photo as a dynamic layer (network performance).

I can add lods for the 1:1000 and 1:500 scales, but is it possible to display the basemap tiles with a lower resolution instead of blank tiles or a no data picture at  highter scales ?


I had a similar issue.  Here's a suggestion.  Create the cache definition with LODs up to 1:500.  Set the cache generation to manual.  Also select build cache on demand.  Once the service is published, manually generate the cache up to 1:2000.  If a user happens to zoom in closer, the cache will be built on demand for that area.
