Hi all,
this is the first time I use Tilecache. I'm trying to generate tiles for a
Map (that I can visualize successfully in OpenLayers with Mapserver). The
.map file is as following:
----
#
# Start of map file
#
#
NAME NAVSTREETS
STATUS ON
SIZE 600 600
SYMBOLSET "/var/www/maps/symbols.sym"
EXTENT 12 41 13 42
SHAPEPATH "/var/www/shapes/"
IMAGETYPE png
IMAGECOLOR 150 150 150
#
# Start of web interface definition
#
WEB
#MINSCALE 2000000
#MAXSCALE 50000000
IMAGEPATH "/tmp/ms_tmp/"
IMAGEURL "/ms_tmp/"
METADATA
"wms_title" "navstreet map"
"wms_onlineresource" "http://213.199.15.252/cgi-bin/mapserv?map=ms.map&"
END
TEMPLATE "test.html"
END
# Layers
LAYER
METADATA
"queryable" "true"
"wms_title" "GreenA"
END
TEMPLATE "test.html"
NAME GreenA
TYPE POLYGON
STATUS ON
DATA LandUseA
CLASS
NAME "Streets"
OUTLINECOLOR 0 255 0
COLOR 0 255 0
END
END # layer
END # MAP
----
The following is my tilecache.cfg file:
----
[cache]
base = /tmp/tilecache
type = Disk
[basic]
layers = GreenA
spherical_mercator = no
data_extent = 12,41,13,42
extension = png
url = http://213.199.15.252/cgi-bin/mapserv?map=ms.map
metatile = no
bbox = 12,41,13,42
type = WMS
----
The layer is deriving from a shapefile. Then I try the command:
python tilecache_seed.py "http://213.199.15.252/cgi-bin/tilecache.cgi?"
basic 0 5
and I get the error
msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS must be
valid for all requested layers.
The point is that I don't want to project my map, so as far as I know, I
haven't to set a projection object in mapfile. Is it mandatory to fullfill
the tilecache requisites? How can I produce tiles from map that are usable
by OpenLayers?
Thank you all,
Damiano Morosi
