ImageServer: can't retrieve rasters boundary

NicolasGIS

Hello,

In a webapplication, I using an ImageServer to query pixels values of several rasters through an ImageServer.

I would like to extract the boundaries of the rasters so as to expose them to the end users of the web application (so that they know the area covered by the data they querying). I can't find a way to do so from an ImageServer service. If I publish the mosaic dataset as a MapServer, it's possible but ideally I would to avoid multiplying services for resources optimization.

Did I miss anything ? 

Thanks,

Nicolas

 if the source of the image service is a mosaic dataset, which contains multiple images inside, you will be able to use these image service operations:

query boundary to get the boundary of the whole mosaic datset:

query the geometry of each item that contains the x,y when you query pixel values.
