What’s GeoNode

GeoNode at a Glance GeoNode is a platform for the management and publication of geospatial data. It brings together mature open-source software projects under an easy to use interface. With GeoNode, non-specialized users can share data and create interactive maps.

Capabilities • Import geospatial datasets, documents and media • Create thematic maps , dashboards and geostories • Manage granular security, permissions and sharing for users and groups • User with appropriate permissions can edit layer metadata, which are exposed by OGC CSW and REST, to provide search/discovery capability • Users with appropriate permissions can edit layer styles and data (for vector layers) • GeoNode exposes a number of standards for each layer: OGC (WMS, WMS-C, WFS, WFS-T, WCS, CSW) and mass market search standards (OAI-PMH, SRU, OpenSearch) • Full control through a RESTful API

Capabilities DATASETS DOCUMENTS LOCAL FILES Upload from local filesystem REMOTE SERVICES OGC WMS GeoNode ArcGIS Server Custom harvesters REMOTE FILES (wip) Links (URLs) to remote files

GeoNode at a Glance • It’s also a web framework based on Python and Django to allow people to implement SDIs and bespoke Geospatial applications.

GeoNode at a Glance

The Community • GeoNode code is made of several components, hosted on GitHub under the GeoNode organization • The GeoNode Project Steering Committee (PSC) governs the GeoNode project. • Users and developers mailing list, and a Gitter chat are the main communication channels for the community. https://github.com/GeoNode

GeoNode 4.1.0

The new importer • A brand new importer service, which serves the upload tools and API • The old importer: • two independent asynchronous flows (GeoNode and Geoserver) to be coordinated • not very well managed execution paths in case of errors • dependency on Geoserver importer extension • creation and management of the DB data was under Geoserver control

The new importer • Goals for the new importer (1) • GeoNode takes control of the full import execution and the imported data • Only one asynchronous service (running on Celery) • A new orchestrator grants transactional execution of uploads, with strong control on rollbacks in case of exceptions

The new importer • Goals for the new importer (2): • A pluggable system to easily extend the upload to more formats • A modular architecture to customize the import procedure • Support for multilayer formats (GPKG, OSM PBF, etc.)

The new importer

The new importer • Using OGR APIs and on ogr2ogr under the hood • All GDAL/OGR formats are potentially supported

Thesaurus faceting and date filters • Thesaurus filters weren’t ported from GeoNode 3

Thesaurus faceting and date filters • Only thesaurus keywords assigned to at least one resource are listed • Starting with GeoNode 4 thesaurus can be uploaded as RDF files through the Django Admin

Thesaurus faceting and date filters • Date filters were also restored. • Resource reference date (publishing, creation or revision) is used

Faceting… work in progress • Filters are undergoing a deep refactoring: • Improved performance • Proper faceting will be available soon, with cascaded filtering and resource counts • Support for additional and configurable filters types • Improvements to the spatial filter Most of this will be available with GeoNode 4.2.0

Time series • Previous versions had an optional upload step for the configuration of datetime field, in case GeoNode found one or more fields eligible for a time series dataset • This workflow was confusing and not very robust

Time series • The optional configuration of vector time series can now be done at a later time, through the Settings tab inside the Metadata editing page

Time series • Only vector formats that provide date(time) fields natively, for example ESRI Shapefile and GeoPackage, are supported

Linked Resources • Maps (n) <—> (n) Layer -> Dataset Map A Map B Layer X Layer X Layer X Dataset X Dataset X Dataset X

Linked Resources • Map → Dataset(s)

Linked Resources • Dataset -> Map(s)

Linked Resources • Document -> Dataset(s) and/or Map(s) • Links can be set with the “Link to” field inside the document metadata editor

Linked Resources • A new model for linking resources is under design • The goal is to be able to set and manage references between any kind of resource • support FAIR principles • more control over the lifecycle of resource dependencies

Extended REST API • The complete information can be obtained for each type of resource, including • metadata • download, embed and share URLs • OGC services • share options • linked resources • Custom metadata JSON data (extra metadata) can be edited • Creation of remote documents

Upgrade to Geoserver 2.23.0 • Granular Geofence rules for WPS processs can now be configured in Geoserver (starting from version 2.23.0) • Security access control for direct requests to WPS based export services can now be managed from GeoNode

Upgrade to MapStore 2022.02.xx • Paving the road to a more extended integration between GeoNode and MapStore, like • 3D viewer (based on Cesium) • Application Context Manager

The future

Features under development • Improved and extended filtering and faceting • Extended configurability of the filter and info panels • Custom layouts for the main catalog viewer, filters and info panels positioning • Multiple ISO contact roles • Custom download providers (static protected downloads, external storage, etc.) • CSV handler with JSON Tabular Data Resource support • Generic and pluggable OIDC SocialAccount Provider

Upgrade • Are you using an older version? Upgrade! • User/Developer lists and Gitter typically covers only supported versions. Today it means only 4.0.3 and 4.1.0 • Security fixes and installation support on new OSs being added to supported versions only! • Moving data from old versions will be much harder if not impossible • Web interfaces and GIS clients will be much different. No one will be able to backport fixes or improvements to the old ones. • Please upgrade your GeoNode installations!!!
