Hi there,
From your request paramter (layers=dream_pm25), I am assuming that you
are trying to access the 2nd layer in your example. What is the content
of your tileindex file "pm25_time_index" ? Is there a reference to the
D031007_t21.pm25_raw file in there ? I am assuming at this point that
Grass is built into GDAL and your are able to load it properly (using
something like gdalinfo and your grass raster, should let you know if it
opens properly).

Hello,
I am using Mapserver 4.10.1 on Red Hat Enterprise 3.
I am trying to display a GRASS raster image with WMS time support. I
have created a tileindex using gdaltindex, imported the tileindex
shapefile into PostGIS, and added a timestamp column containing the date
and hour in an acceptable format (e.g. 2007-04-16 01:00:00).
My mapfile entries for the tileindex, and raster layer are:

My WMS request looks like this:
http://phairs-devel.unm.edu:8080/cgi-bin/mapserv?map=mapmodule_wms.map&VERSION=1.1.1&REQUEST=GetMap&BBox=-120.000,26.000,-97.000,44.000&SRS=EPSG:4326&Width=459&Height=360&Layers=dream_pm25&TIME=2007-04-06T08
And, the error I get is below:
<?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM
"http://schemas.opengeospatial.net/wms/1.1.1/exception_1_1_1.dtd";>
<ServiceExceptionReport version="1.1.1">

</ServiceException>
</ServiceExceptionReport>
Note how the raster referenced in the error is different from that
referenced in the WMS request. I can find no reference to the raster
referenced in the error output anywhere in my mapfile.
I would appreciate any insight into this problem.
Thanks, Bill
