I found that both TileCache and GeoWebCache are lacking in their capabilities

being able to distribute the tiles over redundant servers.


Securing funding for these things proved to be quite difficult. I've 
recently started looking into this again (and a big cleanup), but it's 
vaporware at this point.


That said, GWC has something called request filters, which were written 
to support datasets with sparse coverage. The included implementations 
use 1 bit rasters generated directly by the WMS, or pregenerated files 
from disk. It's not well documented, but you can find it in the 
configuration schema docs. A request filter based on shapefiles was also 
submitted to the list two days ago.


If a BoF session happens I'd be very interested in a summary, 
unfortunately I'm not able to attend this year.

Re: [OSGeo-Discuss] is TileCache alive ?

2010-09-01 Thread Chris Holmes 
GeoWebCache supports some basic statistics, see like
http://maps.opengeo.org:9090/geowebcache/home

Better statistics should move forward as we just got a monitoring framework
in GeoServer, see http://geoserver.org/display/GEOS/Monitoring  We'll start
with also monitoring GWC requests, and it shouldn't be too hard to also port
that to standalone.  Should be able to cluster that as well, to gather stats
in to one database.

I think we've done some work distributing tiles over redundant servers, but
didn't build anything specific in GWC for it.  Would be interested to hear
on that list or add to the roadmap exactly how you'd like that to work.

The other recent GWC work has been to be more transaction aware, using Etags
to keep clients more up to date, and subscribing to GeoRSS feeds or direct
to GeoServer transactions.  Oh, and Gabriel also recently added LFU and LRU
caching, so you can just set your max cache size and GWC will delete the
least frequently used if it hits that limit.  Hrm, looks like both of those
need more documentation though.

But I think both TileCache, GeoWebCache and others are open to going to the
next level of tile management, just need contributors or funders.

I'm speaking right after you on my first attempt for a tilemanagement tool 
(TileSeeder http://code.google.com/p/tileseeder/ a bit more alpha than I hoped 
by now though) and after me Till Adams compares mapproxy, tilecache and 
geowebcache. That should give a reasonable crowd who might be interested in 
such a BoF :)

I'm not sure why the fact that the software hasn't been released since 
18 months ago makes it dead. There have not been any bugs reported that
neccesitate a new release, so far as I'm aware. (If you're aware of one,
you can feel free to bring it to the mailing list.)

WSGI support was available since 1.4 or so, so if you'd like to use 
mod_wsgi with TileCache, you can. I still use mod_python, and no one
has offered a significant patch to the documentation to improve the 
documentation for various mechanisms.

While TileCache may be a somewhat idle project, it's far from dead: I am
actively maintaining the community resources, and handling questions to the
mailing list in the same way that I always have. 

TileCache is simple, and easy to set up. It is used to serve literally
millions of tiles every day by at least dozens of deployments (my guess
is that it's more like hundreds). It doesn't solve every problem for
every user, but it provides a simple framework and has been extended and
abused for many many things, and I don't see that changing any time
soon.

I can only speak for MapProxy and it does support selective pretiling (seeding 
polygon areas, that is) and it supports empty/single color tiles with symbolic 
links.
It is also possible to cascade MapProxy, but there is no enterprisey SOAP 
interface for that :)

But I have to agree with you, there is still lots of room for improvements on 
the tool side. Maybe it is time for a tiling BOF at the FOSS4G?

I'm also interested in new developments in tiling.
I found that both TileCache and GeoWebCache are lacking in their capabilities 
to handle and manage (selective pretiling, deleting, handling empty-tiles) vast 
amounts of tilesets or more 'enterprise' oriented functions like statistics and 
being able to distribute the tiles over redundant servers. 
GWC does have several things in its roadmap: 
http://geowebcache.org/trac/wiki/roadmap but development seems pretty much 
non-existent since the last release (although it seems to pick up again).

Since tiling is becoming more accepted by dataproviders I think it is time to 
work on next level tile management
