Hi,
One alternative is to publish the raster index with footprint polygons and
attribute data as a WFS feature type and use WFS requests with suitable filters
(location, time, other attributes) for queries.

Thanks Simone,
Considering that number of raster will eventually become rather large I will
move to postgis eventually - at this point i needed something to work.
However that doesn't really help me with figuring out how much data there is
i.e. what is the last or first date (as the index is based on the date).
Is there a way by query to find out ? - Obviously as you can see by now - I am
not normally working much in the GIS world.
as to your question - yes and yes.
Cheers
Uwe

Ciao Uwe,
my suggestion is as follows:
-1- use postgis instead of shapefile for indexing your files
-2- add the incoming file directly to the postigs table used for
indexing. GeoServer will pick it up from there
That said, I can provide some more help on how to do this, but I
believe it would be good also to have some additional info on which
type of raster data you are using, as follows:
- subsequent raster covers the same area at different time?
- all rasters have the same spatial resolution and CRS?

Hi Simone,
thanks for the reply -
Index rebuild: at the moment i run a cron job to pick up new images and
rebuild the index with a little java program which ditches the old one and
builds a new one using CatalogBuilder (pls tell me if that is the wrong way
to go about it) - 8 lines of code.
return code: could it be an option to configure that - even in the mosaic
properties file (that way you don't need to drag in into the ui in the first
instance)?
as this is a show stopper at the moment, is there a way to query the store
to get the available start and end time ?
Many thanks
Uwe

Ciao Uwe,
a preliminary thing, if you are adding new granules to an existing
mosaic I would rather use postgis as an index and simply ad a new row
when new data is added.
That said, _right now_ the default behavior is as you see, that is if
you make a request in the right area but with improper TIME values you
get a void image back.
I believe your request sound reasonable but it might break existing
existing clients. Anyway, if you file an enhancement request this
might spawn some discussion
with the other devs to see what we can do to achieve the requested behavior.

Hi list,
I am using the imagemosaic plugin to serve geotiff's produced daily (the
store index gets rebuild after a new image gets added - that works fine).
If i query for a particular date which doesn't exist in the index, an empty
image gets returned - to my mind it should return a 404.
Could somebody please clarify the response process - and - is there a way to
change that response to i.e. 404?
Cheers
Uwe
