I have local files of the already built cache. Now I try to configure a layers which gets the cache layer and shows it, but the problem is that I can't make it ignore the original "sources" because it always asks me to specify the source and I don't want it to try get new layers from the server.
layers:
- name: Earth
title: EarthA
sources: [eartch_cache]
caches:
earth_cache:
grids:[gm_flat]
sources: [] #<- I can't do this, although I want something like that
globals:
cache:
base_dir: S:\CACHCE
It's not the whole configuration but its the important parts…
Is there any way to make MapProxy work with only cache?
I'm not familiar with MapProxy.
Best Answer
Leaving the
sources
array empty is allowed when you specify an explicitcache
property. The following example uses anmbtiles
cache, but any cache format should work:When you use the
local_only
cache in a layer, it will load its data fromcache_data/local_only.mbtiles
only.I tested this with MapProxy 1.8.2, but I was unable to find the matching entry in the change log, so I don't know what the first version is that supports this feature.
Update
I just found the following statement in the caches/mbtiles section in the docs:
Now that version 1.13.0 is out, this applies to additional cache types, such as geopackage files and s3 sources. So the quote above does not mean it can only be done with mbtiles exclusively.
