Daniel,
Thank you for your answer.
Generally, I use gdaltindex to create a shp file for spatial index. Do
you mean I need to add a time attribute into this? Could you give me an
example? Thanks a lot.
That's correct. You need to use a script or some manual method to add
and populate a time attribute in the DBF of the tileindex that was
created with gdaltindex.
I do not have an example, but you can read more about this approach here:
http://mapserver.org/ogc/wcs_server.html#spatio-temporal-indexes
It may be easier to fill in the time attributes if you use a PostGIS
table instead of a shapefile as the tileindex. There is an example of
the corresponding layer definitions here:
