Imagemosaic with CoverageNameCollector

Question

I'm trying to get an Imagemosaic of Sentinel2 data with one coverage for each band to work.

As described in the docs, I want to make use of the CoverageNameCollector property. But the docs are very vague about it and I cannot get it to work. I always end up with just one Coverage.

Beisdes the official docs, I did not find any other source for documentation or tutorial.

My indexer.properties file looks like this:

GranuleAcceptors=org.geotools.gce.imagemosaic.acceptors.HeterogeneousCRSAcceptorFactory
GranuleHandler=org.geotools.gce.imagemosaic.granulehandler.ReprojectingGranuleHandlerFactory
HeterogeneousCRS=true
MosaicCRS=EPSG\:4326
TimeAttribute=time
PropertyCollectors=TimestampFileNameExtractorSPI[timeregex](time),CRSExtractorSPI(crs)
CoverageNameCollector=org.geotools.gce.imagemosaic.namecollector.FileNameRegexNameCollectorSPI:regex=(B[0-1][0-9]).jp2$
Schema=*the_geom:Polygon,location:String,time:java.util.Date,crs:String
CanBeEmpty=true

Example Filename: T60VXJ_20170421T232711_B03.jp2

I use current development snapshot of GeoServer (2.12).

Answer 1

I made it working, there were two issues with my indexer.properties:

1. The name of the Property is CoverageNameCollectorSPI instead of CoverageNameCollector. It was a typo in the docs, but got updated (thanks @Daniele Romagnoli)

2. FileNameRegexCollector uses the BaseName of the file so the extension is not part of the parsing.

Working solution:

CoverageNameCollectorSPI=org.geotools.gce.imagemosaic.namecollector.FileNameRegexNameCollectorSPI:regex=_(B[018][0-9A])
