State of GeoNode - FOSS4G 2023

State of GeoNode - FOSS4G 2023

This presentation will introduce the attendees to those which are GeoNode's current capabilities and to some practical use cases of particular interest in order to also highlight the possibility of customization and integration.

We will provide a summary of new features added to GeoNode in the last release together with a glimpse of what we have planned for next year and beyond, straight from the core developers.

    core We actively participate in OGC working groups and get funded to advance new open standards We support standards critical to GEOINT
  3. 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.
  4. 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
  5. 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
  6. 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.
  7. 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
  8. Releases History • June 2023, GeoNode 4.1.0 • August 2022,

    GeoNode 4.0.0 • June 2022, GeoNode 3.3.2/4.0RC1 • February 2022, GeoNode 3.2.3/3.3.1/4.0RC0 • November 2021, GeoNode 3.2.2/3.3.0 • July 2021, GeoNode 3.2.1 • April 2021, GeoNode 3.2.0 (Django 2.2.16, GeoServer 2.18.2) / GeoNode 3.1.1 (last 3.1 release) • May 2020, GeoNode 3.0 (Django 2.2.13, GeoServer 2.16.2) / GeoNode 2.10.4 (last 2.10 release) • April 2014, GeoNode 2.0 (Django 1.5.5, GeoServer 2.5, pycsw 1.8.6, django-polymorphic, bootstrap, Ubuntu 12.04 support) • August 2010, GeoNode 1.0-beta
  9. Demo instances • You can play with the online demo

    instances • master https://development.demo.geonode.org • 4.1.x https://stable.demo.geonode.org
  10. 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
  11. 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
  12. 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.)
  13. The new importer • Using OGR APIs and on ogr2ogr

    under the hood • All GDAL/OGR formats are potentially supported
  14. 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
  15. Thesaurus faceting and date filters • Date filters were also

    restored. • Resource reference date (publishing, creation or revision) is used
  16. 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
  17. 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
  18. 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
  19. Time series • Only vector formats that provide date(time) fields

    natively, for example ESRI Shapefile and GeoPackage, are supported
  20. Linked Resources • Maps (n) <—> (n) Layer -> Dataset

    Map A Map B Layer X Layer X Layer X Dataset X Dataset X Dataset X
  21. Linked Resources • Document -> Dataset(s) and/or Map(s) • Links

    can be set with the “Link to” field inside the document metadata editor
  22. 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
  23. 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
  24. 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
  25. 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
  26. 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
  27. 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!!!
