public List<GridCoverage> getSources()
GridCoverage
was produced from
an underlying dataset, the returned list is an empty list. If the GridCoverage
was
produced using org.opengis.coverage.grid.GridCoverageProcessor
, then it should
return the source grid coverage of the one used as input to GridCoverageProcessor
.
In general the getSources()
method is intended to return the original
GridCoverage
on which it depends. This is intended to allow applications
to establish what GridCoverage
s will be affected when others are updated,
as well as to trace back to the "raw data".
