Map Server tiles: displaying a tile map beyond tile levels

Boyang_Wang

Hello,

I am wondering if there is a way to displaying a tile map beyond tile levels using existing tiles displayed in lower resolutions. For example, if I build tiles for level 0-20, when I zoom to level 21 the tile map will disappear. I want it to still display the map in level 21 using tiles created for level 20. Is it possible to set up like this?

Thanks!

I figured out two ways:

1. In map viewer, you can manually set the visibility level of the tile layer to any scale regardless of the tile levels, so that the tile layer can be displayed in map viewer in all scales. However, if you use the map as a custom basemap, the Basemap Gallery widget in Web AppBuilder will not respect the visibility setting.

2. Modify the service properties in ArcGIS Server Administrator if you are using Enterprise. Change "maxScale" property to "70.5310735", and Basemap Gallery widget in Web AppBuilder will respect this setting.
