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.

2. GeoSolutions Enterprise Support Services Deployment Subscription Professional Training Customized Solutions GeoNode • Offices in Italy & US, Global Clients/Team • 40+ collaborators, 30+ Engineers • Our products • Our Offer
3. Affiliations We strongly support Open Source, it Is in our core We actively participate in OGC working groups and get funded to advance new open standards We support standards critical to GEOINT
4. What’s GeoNode
5. 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.
6. 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
7. 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
8. Capabilities DATASETS DOCUMENTS MAPS GEOSTORIES DASHBOARDS GEOAPPS
9. Capabilities MAPS GEOSTORIES DASHBOARDS GEOAPPS WMS WMTS WFS CSW embedded viewers
10. 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.
11. GeoNode at a Glance
12. 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
13. 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
14. Demo instances • You can play with the online demo instances • master https://development.demo.geonode.org • 4.1.x https://stable.demo.geonode.org
15. GeoNode 4.1.0
16. 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
17. 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
18. 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.)
19. The new importer
20. The new importer • Using OGR APIs and on ogr2ogr under the hood • All GDAL/OGR formats are potentially supported
21. Thesaurus faceting and date filters • Thesaurus filters weren’t ported from GeoNode 3
22. 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
23. Thesaurus faceting and date filters • Date filters were also restored. • Resource reference date (publishing, creation or revision) is used
24. 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
25. 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
26. 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
27. Time series • Only vector formats that provide date(time) fields natively, for example ESRI Shapefile and GeoPackage, are supported
28. Linked Resources • Maps (n) <—> (n) Layer -> Dataset Map A Map B Layer X Layer X Layer X Dataset X Dataset X Dataset X
29. Linked Resources • Map → Dataset(s)
30. Linked Resources • Dataset -> Map(s)
31. Linked Resources • Document -> Dataset(s) and/or Map(s) • Links can be set with the “Link to” field inside the document metadata editor
32. 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
33. 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
34. 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
35. 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
36. The future
37. 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
38. 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!!!
