[mapserver-users] .map

[Lowell Filak]

You could also use the shapefile as the tileindex for the raster layer that includes all the images for a given date/product by using mapscript to change the layer->{tileitem} parameter. The shapefile would have a different field name for each date/product combination and switching the tileitem would change which set of images are used to render the map.
My 2 cents.
