Dear Danielle- That fixed it! imageindex:Integer is required in the schema for use by the underlying I/O. I thought that part of the schema was for GeoTiffs or something, so I edited it out when I copied the example.
Sorry for the trouble, and THANK YOU for spending the time to help me sort this out. -Paddy McCarthy. On Wed, Apr 6, 2016 at 4:37 AM, Daniele Romagnoli < [email protected]> wrote: > Hi Paddy, > Ah!
