Hi Varun,
It looks rather like a question for the tilecache-users list, but I can give
you a hand.
I think you didn't specify any layer when running tilecache_seed.py
Please try :
tilecache_seed.py [your_layer_name_as_set_in_tilecache.cfg] 0 5
where 0 and 5 are zoom start and zoom end. You can adapt this last one
depending on how many levels you set for your layer.
Run it from the directory where tilecache.cfg is, to avoid problem if you
have many of them...
Regards,
Guillaume

Hello,
I have got this (tilecache with mapserver on google maps) working
finally after a lot of problems but I now really need to know about
how to do a pre-cache of all the tiles from mapserver. I am running
tilecache 2.10 on Windows with mapserver ms4w from maptools.org. I
tried running "tilecache_seed.py" as per the suggestion above but it
always ends up in the following error
Traceback (most recent call last):
File "C:\ms4w\Apache\cgi-bin\tilecache-2.10\tilecache_seed.py", line 9,
in <mo
dule>
TileCache.Client.main()
File "C:\ms4w\Apache\cgi-bin\tilecache-2.10\TileCache\Client.py", line
153, in
main
layer = svc.layers[args[0]]
IndexError: list index out of range
Any help in this regard would be great.
Thanks,

Hi Roger,
I am trying to get my mapserver and tilecache work together but its
somehow not working. I am using the same projection as you in all my
layers and the mapfile. (This works when I call my mapserver directly
from google and hence the projection is right).
Here is my mapfile (Only things that might be important).
MAP
EXTENT -173 5 -45 75
IMAGETYPE PNG
PROJECTION
"init=epsg:4326"
END
WEB
METADATA
wms_srs "EPSG:4326 EPSG:900913"
END
....
END
LAYER
....
PROJECTION
"init=epsg:4326"
END
END
Next I added the 900913 epsg to the proj.4 of mapserver and made the
required changes in tilecache.cfg file as you specified.
[google-tiles]
type=MapServerLayer
mapfile=C:/ms4w/apps/QCTGIS/drawMap.map
metaTile=true
metaSize=2,2
metaBuffer=0,500
layers=tr20_d00
spherical_mercator=true
srs=EPSG:900913
I am not sure if the linkn I am using is wrong. I have tilecache
installed in the cgi directory of the apache server that was installed
using "ms4". The example index.html that comes with tilecache works
fine and I can see the images being cached. Also my mapserver directly
works fine. Can you tell me what is it that I am doing wrong here? the
link I use for the tileUrlTemplate in google maps is
"http://127.0.0.1:8123/cgi-bin/tilecache-2.10/tilecache.cgi/1.0.0/google-tiles/{Y}/{X}/{Z}.png?type=google";.
I can also see that this call gets initiated in the apache logs
(access.log) but nothing happens therafter. I don't even know if this
is failing at tilecache end and mapserver isn't being called at all or
at mapserver's end where the image is not being sent by mapserver. Can
you help me out here?
Thanks a lot.

Ahh, ok. I'm not sure in what fashion you are using TileCache, but my
experience has been with using it to create tiles to display in Google
Maps. Google Maps uses the projection which is EPSG:900913. I
believe there are other codes for it, but that is the one I use.
All of my source data for the MapServer projects I make are in
EPSG:4326. So there are 3 things I need to do in order to make the
Tilecache output tiles align correctly in Gmaps.
1. I set both the mapfile and the layer projections to EPSG:4326.
MAP
NAME 'v2_80m_global'
PROJECTION
"init=epsg:4326"
END
LAYER
NAME 'imagery'
PROJECTION
"init=epsg:4326"
END
<snip...>
2. I explicity allow for a wms request to be made for the layer in
EPSG:900913 by setting the following in my MapServer LAYER:
METADATA
"wms_srs" "EPSG:4326 EPSG:900913"
<snip...>
3. I define my TileCache layer so that it requests images from
Mapserver in EPSG:900913.
[v2_20m_global]
type=MapServerLayer
mapfile=/var/www/mapfiles/v2_20m_global/v2_20m_global.map
metaTile=true
metaSize=2,2
metaBuffer=0,500
layers=imagery
spherical_mercator=true
srs=EPSG:900913
That's what works for me.

Thank you Roger, for your response. I have done that but I do not
understand how tilecache works. The images that are returned from
mapserver
line up perfectly. But the images returned from tilecache do not align
very
well (they're distorted). If tilecache is simply caching the returned
images then I do not understand where this distortion comes from. Any
thoughts?
Thanks!

Your request is somewhat lacking in detail, but assuming that your
goal is a simple one, here is one way to accomplish this.
1. Create a MapServer project that displays your shapefile in whatever
style you choose.
2. Setup a TileCache instance that points to your MapServer project.
3. Run the tilecache_seed.py script to pre-generate tiles.
