[mapserver-users] Kernel Density maps and WMS Time

[Berger, Cora]

Dear Domenico,
I created a WMS with TIME-Parameter successfully for historical orthophotos. You find the documentation for the time-parameter in mapfiles here: http://mapserver.org/de/ogc/wms_time.html

In your second layer try to change this:
Instead of 
CONNECTIONTYPE KERNELDENSITY
CONNECTION "the_geom"
Try
TILEINDEX "the_geom"
TILEITEM "location" 	#if the name of the column with the information where the data is stored is called like this
FILTER (`[datetime]` = `2006-06-23T03:10:00Z`)

In my case only the tileindex is stored in postgis and the raster data is stored in a filesystem. The column "location" of the tileindex contains the path to the folder where the raster data is stored.
Have you set up a mapfile using raster data and tileindex before? Maybe it helps to read the tileindex-documentation, too to get a better understanding of how the tileindex works. The WCS documentation also contains a part about spatio-temporal-tileindexes http://mapserver.org/ogc/wcs_server.html#spatio-temporal-indexes

Cheers 
Cora
