Hello,
I've been working with mapserver to get a map with time support, time
parameter, I followed the tutorial in documetation
http://mapserver.org/ogc/wms_time.html and this post
http://osgeo-org.1803224.n2.nabble.com/Accessing-images-using-time-dimension-td1991324.html#a1991324
and I can't run the mapserver to change the image with a time parameter.
I test several configurations but any works, the last is the same like
the post in the maillist, this is what i've done:
in a postgis database
create table satellite (image_path text, image_time timestamp);
select AddGeometryColumn('satellite', 'the_geom', 4326, 'POLYGON', 2);
insert into satellite (image_path, image_time, the_geom)
values ('/home/vbox/Downloads/animacio/sat1.tif', '2007-05-11 10:00Z',
GeomFromText('POLYGON((-31.82 75.55, -31.82 26.5, 51.31 26.5,51.31 75.55,
-31.82 75.55))', 4326));
insert into satellite (image_path, image_time, the_geom)
values ('/home/vbox/Downloads/animacio/sat2.tif', '2007-05-11 11:00Z',
GeomFromText('POLYGON((-31.82 75.55, -31.82 26.5, 51.31 26.5,51.31 75.55,
-31.82 75.55))', 4326));
and the map file:
LAYER

END
END
LAYER

END

END
TILEINDEX "time_w" # Layer name containing time index
TILEITEM "image_path" # DB column containing path to image
END
anyone finds some error?
Could you provide an example URL you are using to test out the WMS-T? I
am using WMS-T on 5.6.3 without any known issues. Please note that if
your time table gets very large, you may hit this quirk:
