Hello,
I have two similar tilesets configured in Mapcache. One of the tilesets di=
splays 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 ev=
ery 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 s=
pace 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 tile=
sets.
Thanks!
Sincerely,
