ImageMosaic + S3-Geotiff

GeoServer - User mailing list
Hi All !

Is there a way to make ImageMosaic datastore to access granules via S3
protocol?

Our ImageMosaic index is handled by a PostGIS table and location attribute
is set to 's3://bucket/objectkey'.
Also we have S3-Geotiff plugin installed and it works correctly for its own
datastore.

Can we achieve our goal by setting SPI in mosaic.properties like
PathType=URL
SuggestedIsSPI=org.geotools.s3.S3ImageInputStreamImplSpi
SuggestedSPI=org.geotools.s3.geotiff.S3GeoTiffReader

Thank you in advance.

Best Regards, Boris.

Re: ImageMosaic + S3-Geotiff

I have tried to do the same.

SuggestedSPI=org.geotools.s3.geotiff.S3GeoTiffReader fails with this
exception:  https://pastebin.com/bKPRVuKR <https://pastebin.com/bKPRVuKR>  

Is there a way to modify S3GeoTiffReader to allow it to be instantiated in
AbstractGTDataStoreGranuleCatalog
<https://github.com/geotools/geotools/blob/master/modules/plugin/imagemosaic/src/main/java/org/geotools/gce/imagemosaic/catalog/AbstractGTDataStoreGranuleCatalog.java#L132>
?

I'm running Geoserver 2.16-RC so that I have  this fix
<https://github.com/geotools/geotools/commit/67a8a27e524a16656b9211255800b87674423286>
, which I thought may have been causing issues with S3GeoTiffReader.

I found  this comment
<https://github.com/geotools/geotools/pull/1829#discussion_r184628591>  
from a pull request for issue  GEOT-5956
<https://osgeo-org.atlassian.net/browse/GEOT-5956>   which suggests that
using S3 in an ImageMosaic may be possible, but I couldn't find anything in
the documentation. I may be on the wrong track with using S3GeoTiffReader
for the SuggestedSPI.

My complete mosaic.properties:

SuggestedSPI=org.geotools.s3.geotiff.S3GeoTiffReader
