Class CoverageSlicesCatalog.WrappedCoverageSlicesCatalog

Object

CoverageSlicesCatalog

CoverageSlicesCatalog.WrappedCoverageSlicesCatalog

Enclosing class:

CoverageSlicesCatalog

public static class CoverageSlicesCatalog.WrappedCoverageSlicesCatalog
extends CoverageSlicesCatalog

CoverageSlicesCatalog always used an hidden H2 DB to store granules index related to a specific file.

Starting from 14.x it also can be setup on top of a shared PostGIS datastore.

Using a PostGIS shared index, we need to add a LOCATION attribute to distinguish the different granules, as well as add a Filter setting the LOCATION value to each query from a reader (1 reader <-> 1 file <-> 1 location)
