Hello,
I have to work offline a lot. Before I save the osm file I always pan around
the area at the greatest zoom level.
When I re-open the file offline, I rarely get enough high detail images to
work effectively.
Is there a way to cache the images. I've read several josm wiki pages that all
seem to be out of date regarding this process. I usually use Bing or Mapbox.
The following does not seem to be available to me in the latest JOSM
How do I use WMS images offline in JOSM_ - OSM Help
"Caching
To reuse the tiles over JOSM sessions without having the reload them from the
server, right click on the WMS layer and set a bookmark. During the next
session, select the new WMS created by the bookmark in the WMS memu.
Additionally, you may want to modify the following values in the preferences :
cache.wmsplugin.expire 1 : this is a time in second until the tiles are
invalidated. 1 means "never flush". cache.wmsplugin.maxsize 999999999 :
maximal size of the cache (probably in MB) Even though you have to download an
area "manually", you can work offline using this technique. "
I just tried that Bing imagery is automatically cached in my JOSM and previously
loaded tiles are displayed upon restart without network connection. There is no
need for setting any bookmarks. This definitively outdated paragraph which you
quote refers to the old WMS plugin which was needed before access to WMS servers
was integrated into JOSM.
You might want to look at the preference for the tile cache path: from the
preference menu select the advanced preferences (the lowest icon in the bar) and
search for imagery.tms.tilecache. The default value of this property is only
visible after Bing imagery has been loaded. Make sure that this does not point
to a directory which is cleared during shutdown. Imagery tiles appear in my
cache under .josm/cache/tms/{Bing,Mapbox}/...
To my knowledge there is no configurable timeout for this cache to expire.
Hope this helps
