Steve, Thank you for your reply. I had also thought about configuring the caches at the client level as you suggest. Unfortunately, I do not have control over all of the potential clients as some outside users might connect to my services via Leaflet, OpenLayers, ArcMap, QGIS, etc. It sounds like my best option is to swap caches as you suggest (the political cache will only have 4 zoom levels), and hope outside users either repeat the same process or only use the air photo cache.
Thanks!

That is, you'd have the two caches (air photos and political) but then configure the client to swap at different zoom levels. For example, with Leaflet you could simply set maxZoom/minZoom map attributes. Here's an example that uses a map (1 tileset) at small scales and then transitions to aerial photos w/overlays (2 tilesets) as the user zooms in: http://maps1.dnr.state.mn.us/test/tiles/switch.html Presumably you can tell MapCache to only generate tiles over certain zoom ranges for each tileset - thus reducing disk space. Perhaps I'm miss interpreting your question though. --Steve On Wed, Oct 23, 2019 at 9:29 AM Mark Volz <markv...@co.lyon.mn.us<mailto:markv...@co.lyon.mn.us>> wrote: Hello, I have two similar tilesets configured in Mapcache. One of the tilesets displays a political map at small scales, then changes to an air photo map as the user zooms into the map. The second tileset displays air photos at every zoom level. It would be useful if these tilesets could share a single cache for zoom levels 5-11. This way we could save a significant amount of space on the server. Example #1: Political and Air Photo Basemap: • Zoom level 0-4: Use the cache from the “political map cache” • Zoom level 5-11: Use the cache from the “air photo cache” Air Photo Basemap • Zoom level 0-11: Use the cache from the “air photo cache” Result: • Any tiles at level 5-11, which will take up the majority of the space on the sever will not need to be duplicated between the two tilesets. Please let me know if it is possible to share caches between different tilesets. Thanks!
