package org.geotools.image.io.metadata
Geographic informations encoded in images as metadata.
This package defines a {@link org.geotools.image.io.metadata.GeographicMetadataFormat
geographic metadata format} which is aimed as image format neutral. The metadata format defines a structure
for a tree of nodes in a way similar to the way methods are defined in GeoAPI interfaces. For example it
defines a {@code "CoordinateReferenceSystem"} node with {@code "CoordinateSystem"} and {@code "Datum"}
child nodes.
The {@link org.geotools.image.io.metadata.GeographicMetadata} class contains convenience
methods for encoding metatadata. Metadata are usually given as {@link java.lang.String} or {@code double}
attributes only, but image readers can optionaly attach fully constructed GeoAPI objects if they wish. If
only {@link java.lang.String} and {@code double} are used, then the duty to create GeoAPI objects from them
incomb to the {@link org.geotools.coverage.io} package.
