Can't zoom past 1:71 in web map despite custom basemap

[JoshBerna]

Hey folks, 

I recently published a tile layer from a 1cm/pixel orthophoto of a nearby creek produced from a drone flight. Tile layer was set to pack for LODs 10 to 23.

I'm using a custom basemap in webmap viewer, but I still can't zoom past 1:71. I can change the visible range for the basemap to include all the way up to 1:1, but I cannot change the visible range on the tile layer to include any closer zoom level than 1:71.

Thus I have a two questions:

1. What is likely inhibiting the ability to zoom further on the map? I'd very much like to be able to zoom closer than 1:71, but the button is literally grayed out. Is it because the tile layer itself was only packed for 1:71? Why can't I just zoom closer with no change in resolution?

2. Is there a means of packing a LOD past level 23 when publishing the tile layer? Even a level 24 (1:35?) would be much better. 

Any help is much appreciated.

Hi @JoshBerna 

You might be able to follow this workflow to help over come the issue you are having with the zoom levels 

1. Create a custom tiling scheme XML using ArcGIS Pro’s Generate Tile Cache Tiling Scheme tool.

2. Define additional LODs (e.g., Level 24 = ~1:35.29).

3. Use this custom tiling scheme when creating your tile package (.tpkx) or publishing directly.

4. Publish the tile layer using this scheme—ArcGIS Online will honor it.

I hope this helps in some way

Brilliant, worked perfectly. Thanks Daniel. I didn't know this tool existed.
