Hi,
I have WCS 2.0.1 server (Geoserver 2.12) running and I can get data out in
GeoTIFF format. The output seems to be tiled with 512x512 pixel sized tiles.
The server is advertizing that it supports the WCS GeoTIFF extension and I
tried to control the tiling but with poor success. For example this request is
sending a tiled output
http://localhost:8080/geoserver/ows?service=WCS&version=2.0.1&request=GetCoverage&CoverageID=ortotesti__ortokuva&SUBSET=E(382119,382619)&SUBSET=N(6724181,6724681)&format=image/tiff
By reading the document
https://portal.opengeospatial.org/files/?artifact_id=54813 and related XML
schema http://schemas.opengis.net/gmlcov/geotiff/1.0/gmlcovGeotiff.xsd
I thought that this request should give me a non-tiled image
http://localhost:8080/geoserver/ows?service=WCS&version=2.0.1&request=GetCoverage&CoverageID=ortotesti__ortokuva&SUBSET=E(382119,382619)&SUBSET=N(6724181,6724681)&format=image/tiff&geotiff:tiling=false
However, the result is still a GeoTIFF with 512x512 internal tiles. I also
tried to change the tilesize with geotiff:tiling=true&geotiff:tileheight=256
but I get still 512x512 tiles.
Am I doing something wrong or does Geoserver just not support those GeoTIFF
parameters? I suppose it is OK not to support them because of this sentence in
the GeoTIFF extension specification "Note A server or service not implementing
the requested feature is always free to respond
with an exception." but then the server should send the exception.
