Zoom Into Min. Scale
Although my map service has been set up that the min. scale is set to 150 and a max scale of 0, my Silverlight v2.2 viewer will not zoom into past 1:625?
I've attempted to use the feature zoom factor or the feature zoom scale, but these did not have any effect.
Any suggestions?

Hi Walter,
Are you using a tiled basemap? What's the minimum scale on the tile set?

Edmond,
Thanks for responding. As our standard we use the ESRI http://services.arcgisonline.com/ArcGIS/rest/Services/World_Topo_Map/MapServer as our basemaps which has the following scales set:
Min Scale: 5.91657527591555E8
Max Scale: 1128.497176Walter

I have found that a map can't be zoomed in past the greatest maximum scale amongst all layers in all services in the map. Try examing all services in your map, and all their layers, to find out which one is holding up the zoom. In my Cemetery map, it was our custom tiled cache imaging service that prevented zooming further. After switching to the non-cached imagery, I could zoom to any scale I wanted.

Roger,
Thanks for your response. Funny, I'm applying this to my cemetery map as well!
I only have one basemap, which is our standard arcgisonline:
url=http://services.arcgisonline.com/ArcGIS/rest/Services/World_Topo_Map/MapServer
And our cemetery map service is the only other dataset.
I had to use the Viewer>Mapmodule>Settings tab to get past the max zoom scale.

Roger,
In your cemetery geometry, do you have any upright burial columns known as "Niche Walls"
If so, how are you treating the display of these items in your cemetery data?
Initially, our circular ones are now displayed as circles with lines bysecting it.

I'm facing the same issue. When a tiled map image service is added to the site, the user can't zoom in closer than the lowest cache level (in this case 1:500). Switching to non-cached imagery is not an option for us as my understanding (from ESRI) is the performance will suffer greatly due to the number of users who access our sites. There has to be some way around this. Has anyone found a solution that still allows the use of cached imagery?

Have a look at viewer > map module, and make sure snap to levels is not selected and set a min resolution. I have found using a min resolution of 0.001 lets the user zoom in as far as they want and the tile image service just gets more pixelated. No zoom/scale settings are necessary on the layers. Hope this helps.
Cheers,
Graeme

Thanks Graeme. Unfortunatelty I'm doing this with an HTML5 viewer so no map module settings are available.

We've got around this issue in the SLV, but not sure if the theory holds true in the HTML5 viewer as yet? (we are at 2.2, but 1.9.1 operates mostly with the same theory)
We created a 'dummy' cache, with the extra scales in it (including the normal scales from our other tiled base map services). ie. our lowest was 5000, but our dummy cache now has a couple of extra at 1250, and 2500. One quirk is to keep halving the scales!! so I had a starting point of 5000, I then, in my new cache had to use 2500, and then 1250, and keep going if you like....
The new cache does not contain any data, only the schema in the Layers section, so the application knows what scales are being adhered to. Basically run a really basic cache, stop it, and delete the contents (bundles). Geocortex is only interested in the cache's schema which is read I assume from the conf.xml file.
Place this new dummy cache at the very bottom of the layerlist, and set it's visibility etc. to false so the user does not know about it.
hope that helps

Is there a way to disable Snap to Levels in the HTML viewer? Either through the manager or by manually editing the xml or config files?0
