DefaultGeoreferenceable	Grid with cells irregularly spaced in any given geographic/map projection coordinate reference system.
DefaultGridSpatialRepresentation	Method used to represent geographic information in the dataset.
DefaultVectorSpatialRepresentation	Information about the vector spatial objects in the dataset.

Package org.apache.sis.metadata.iso.spatial Description

Information about the mechanisms (grid or vector) used to represent spatial data. An explanation for this package is provided in the OpenGIS® javadoc. The remaining discussion on this page is specific to the SIS implementation.

Overview

For a global overview of metadata in SIS, see the org.apache.sis.metadata package javadoc.

Null values, nil objects and collections

All constructors and setter methods accept null arguments. A null argument value means that the metadata element can not be provided, and the reason for that is unspecified. Alternatively, users can specify why a metadata element is missing by providing a value created by Nil­Reason.create­Nil­Object(Class).

Unless otherwise noted in the Javadoc, all getter methods may return an empty collection, an empty array or null if the type is neither a collection or an array. Note that non-null values may be Nil­Objects.

Unless the metadata object has been marked as unmodifiable and unless otherwise noted in the Javadoc, all collections returned by getter methods are live: adding new elements in the collection modify directly the underlying metadata object.
