The GIS-Interface is a java library which exposes methods to access / modify spatial data and related metadata. The library is designed to rely on GeoNetwork and GeoServer registered in the infrastructure.

The implementation is based on functionalities exposed by geoserver-manager and geonetwork-manager. These libraries are both developped by GeoSolutions under MIT License.

Modules

The library is distributed in 2 separate modules :

• org.gcube.spatial-data.geonetwork

exposes functionalities to access / write metadata on GeoNetwork. Most applications which need basic functionalities like search and access to metadata should rely only on this component.

• org.gcube.spatial-data.gis-interface

used to manage spatial data to/from GeoServer instances. Applications which generate/publish spatial data in the infrastructure should exploit its functionalities.

GeoNetwork module

In order to use org.gcube.spatial-data.geonetwork in your Maven project, you need to add this dependecy in your pom.xml file

<dependency>
  <groupId>org.gcube.spatial.data</groupId>
  <artifactId>geonetwork</artifactId>
  <version>1.0.0-SNAPSHOT</version>
</dependency>

please, remind to follow guidelines declared in Developing gCube Maven Components.

ISO 19115:2003 metadata compliance

Metadata objects used by the libraries implement GeoAPI interfaces, which are fully compliant to ISO 19115:2003/19139. Current implementation is based on GeoToolkit Metadata module.

Read GeoNetwork metadata

Read Methods exposed by the library are the ones declared by the interface org.gcube.spatial.data.geonetwork.GeoNetworkReader.

Here are some snippets

Get Instance

Please note that the library uses the current scope in order to determine which geonetwork it should rely on.

ScopeProvider.instance.set(...);
GeoNetworkReader gn=GeoNetwork.get();
