Time-Aware Raster Catalog Images Not All Showing

[RyanCoodey]

We have a raster catalog of about 30 images... each image has a start and end time attribute over a span of approximately 30 days (no time periods overlap).  I have served these up on ArcGIS Server as a single layer in both a MSD and a MXD (since image server does not support catalogs).

If I try and use the "Export Map" operation I have some issues.  With no time specified, one of the images always shows up.  But if I specify an Epoch time that I know for sure is associated to one of these images time spans, only about 2 out of the 30 images will show for their corresponding time.

Any ideas why the images won't all show?  It works fine with the time slider in ArcMap... some type of caching limitation with the REST API maybe?  I want to use the time slider in Silverlight and it is producing the same results since the REST API is not sending an image over.

Thanks a lot for any help!

Yes, it is running on 10 prerelease (still waiting for our final auth keys).

I tried the below time, and a few others in seconds, and still nothing 😞

Pls try time extent in the query instead of a time instant and see if it works.
eg: 1217318980000,1227318980000 

If this continues to be an issue with 10.0 Final, please contact ESRI Support for further assistance on this issue.

Thanks

It does the same. It works just like with the instant... it will get about 1 out of the 30 rasters in the catalog as you change the time range around.

I am eager to try it in 10 final... Was there a lot of fixes done between pre-release and final?

[RaviNarayanan]

it will get about 1 out of the 30 rasters in the catalog as you change the time range around.

For my sake of understanding this issue, should there be more than 1 raster returned for the time instant/time extent that was specified? Is it returning the same raster for different time instant/time extents? what is returned when a time extent of null,null is specified?

[RyanCoodey]

Only ONE raster should be returned for a particular time instant.  Each image has a start and end time, and the end time of one image is the beginning of the next.  Each image's time range spans 24 days.  There are about 30 of these images in the catalog, spanning over a period of about 2.5 years.  The attached picture (in the above post) of the attribute table might help you to see the date structure.

So simply put, only one raster should be returned for a particular time instant.  95% of the time I do NOT get even one raster back (when I should)... but 5% of the time I will get one (can be at any time interval, not necessarily the same one when it does show).

Hope that makes sense!

Thanks!!!

Ok, thanks for the details. My initial thought was this behavior could be related to

"NIM053659: Query or ExportMap Image operation in MapService or Feature services does not honor Time Extent with time value containing precision upto milliseconds"

But this was a bug in beta2 and was addressed in pre-release.

[RyanCoodey]

Ahhh, sure sounds like a similar problem...

And to answer your other question, when I set the time to "null,null" I get back the wireframes of the images... as expected since more than 9 should be showing.  Same behavior as specifying no time.

[RyanCoodey]

Still have this same issue with 10 final... time seems to work fine for a feature layer, but not a raster catalog 😞

[RaviNarayanan]

Ryan,

Thanks for checking this with 10.0 Final. Can you please submit a request to ESRI Support with a reproducible case so that we can look into this further?

Thanks

We're having the same issue, has anyone come up with a resolution?
