AbstractGridCoverage2DReader should consider using both overviews and
subsampling at the same time
--------------------------------------------------------------------------------------------------
Key: GEOT-1651
URL: http://jira.codehaus.org/browse/GEOT-1651
Project: GeoTools
Issue Type: Improvement
Components: core coverage
Affects Versions: 2.5-M0, 2.4-RC0
Reporter: Andrea Aime
Assignee: Simone Giannecchini
Fix For: 2.4.0, 2.5-M1
If an image has overviews that do respect a power of 2 scale, picking the right
overview is often enough.
Yet, if the overviews do not follow power of 2, or if the last overview is not
small enough for the desired resolution, it should be possible to apply
subsampling to further reduce the amount of data to be read.
