Time-Aware Raster Catalog Images Not All Showing

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!

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

Hi Naomi,

I had gone back and forth with ESRI support for awhile and we did find a solution.  Sorry, I had meant to post it here and forgot.

While it is a bug for sure that these are not showing up, all we had to do was create pyramids for the rasters and then they would show up.  For some reason server needs those pyramids there which I had not generated for this particular catalog.

Also, another bug that was uncovered... If you serve a catalog with a classified renderer up as a MSD based service it produces a corrupt image each time the image is refreshed (NIM062763).

Hope this helps!!!

I solved this by changing the YEAR field on our mosaic dataset from TEXT (as explained in the directions) to a DATE type.

http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009t000000v1000000.htm

Add the Year field to the mosaic dataset
To make this mosaic dataset time aware, you need to create the new attribute field in the mosaic dataset and add the correct dates. You can do this using geoprocessing tools or using the steps below within ArcMap.

Add the new field to the footprint attribute table
Steps:

  1. [INDENT]Add the master mosaic dataset to ArcMap.

  2. [INDENT][/INDENT]Right-click the Footprint layer and click Open Attribute Table.

  3. [INDENT][/INDENT]You should see a row for each mosaic dataset you added.

  4. [INDENT][/INDENT]Click the Table Options button  and click Add Field.

  5. [INDENT][/INDENT]Type Year in the Name text box.

  6. [INDENT][/INDENT]Click the Type drop-down arrow and click Text.

  7. [INDENT][/INDENT]Click OK.

Thanks very much.  I was having a similar problem, and when I created the pyramids everything was fixed.
