[Tilecache] Tilecache.cgi works fine, tilecache_seed.py bombs...

[Huey Brantley]

I've been struggling with the same problems, however I have now been
able to get tilecache_seed.py to run successfully.

My tilecache.org is:

[campus]
type=WMSLayer
url=http://192.168.0.30/cgi-bin/wms
extension=png
layers=grass,sidewalks,drivesalleys,roads,parking,facilities,artwork,campuswebcams,arealabels,roadnames
bbox=-86.85846389,36.10619167,-86.73637222,36.19093611
metaTile=true
levels=20
maxResolution=1.40625

I run seed as:

./tilecache_seed.py
'http://maps.cpc-fis.vanderbilt.edu/tilecache/tilecache.cgi?' campus0 0
20 -86.85846389,36.10619167,-86.73637222,36.19093611 

This runs fine now but when I view the layer all the tiles are pink.
When I try to view one of the pink tiles I get:

The image
"http://maps.cpc-fis.vanderbilt.edu/tilecache/cache/campus0/15/000/000/010/000/000/007.png" cannot be displayed, because it contains errors.

I view this image with a viewer and it seems fine. 

Searching for a cause and fix.

Thanks,

h

Hi all: I've got tilecache working fine via the CGI script and am moving
on to seeding the cache. My setup is a mapserver
mapfile will all default layers. The following config is working:

[compass]
metaTile=true
type=MapServerLayer
layers=
mapfile=/usr/local/www/docs_maps/compass/compass.map
levels=12
srs=EPSG:29615
bbox=105000,4785000,809000,5489000
maxResolution=5500
extent_type=loose

However, running the seed script like so:

./tilecache_seed.py http://maps.dnr.state.mn.us/tilecache/tilecache.cgi
compass 0 11

flames out with:

###### (0, 0, 0), (1, 1, 0)
Traceback (most recent call last):

<ServiceExceptionReport version="1.1.1">
<ServiceException code="LayerNotDefined">
msWMSLoadGetMapParams(): WMS server error. Invalid layer(s) given in the
LAYERS parameter.
</ServiceException>
</ServiceExceptionReport>

I'm not sure why the config works in one case but not in another, other
than it must have to do with an empty layer list. The URL in the error
snippet does return a valid image. Ideas?

Thanks - Steve
