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.

Re: [mapserver-users] Precache

2009-06-19 Thread Varun saraf 
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.

 All of my source data for the MapServer projects I make are in

 1. I set both the mapfile and the layer projections to EPSG:4326.

 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

2009-06-19 Thread Varun saraf 
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

 main
layer = svc.layers[args[0]]
IndexError: list index out of range

Any help in this regard would be great.

Re: [mapserver-users] Precache

2009-06-19 Thread Guillaume Sueur 

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
