Object

AbstractGridCoverage2DReader

ImageMosaicJDBCReader

All Implemented Interfaces:

GridCoverage2DReader, GridCoverageReader

public class ImageMosaicJDBCReader
extends AbstractGridCoverage2DReader

This reader is responsible for providing access to images and image pyramids stored in a JDBC datbase as tiles.

All jdbc databases which are able to handle blobs are supported.

Additonally, spatial extensions for mysql,postgis,db2 and oracle are supported
