raster as Ascii Grid from Arcgis Server 10.1 by user-defined envelope

Discussion created by jui_caner on Sep 3, 2013
I have a raster with values ??????ranging from 1 to 4, published on ArcGis Server 10.1 as ImageService
I need (in third-party software) to get the values ??????of cells in a user-defined area in the ASCII GRID format.
I am using WCS service, but its not possible to specify "OUTPUT Format = AIGRID" there.
Please tell me how should I solve my problem?

I would be grateful for any help
