Meeting Business Needs with geOrchestra How does geOrchestra help us meet the business needs of our services, combining native and customized functionalities? Providing an application for managing DTDICT, offering thematic map models or even adapted environments to facilitate access to business data, enabling the selection and download of oblique aerial photographs of the territory, or facilitating collaboration among stakeholders for PLUi evolutions; all these needs are made possible thanks to the use of geOrchestra components and their integration into the local authority's IT system. |

2:00 PM |
Datahub - New Features The datahub (GeoNetwork-UI) is constantly evolving. Major new features are being integrated following exchanges within the community (IGN, geOrchestra, SwissTopo). A new version planned for summer 2025 should thus offer support for service and reuse metadata, the addition of an attribute catalog visualization module, pagination of WFS sources, support for Vector Tiles sources, restoration of a quick access bar, and better support for users on restricted access sources. |

A Bit of Géoplateforme on Your Platforms. The Géoplateforme program chose to use the Datahub for the cartes.gouv.fr catalog interface. Since then, several contributions of various kinds have been made, including: * support for the object catalog (featurecatalog ISO19110), service entrusted to Camptocamp * the module for downloading pre-packaged data distributed by the Géoplateforme |
Xavier Thauvin & Melodia Mohad - IGN |
3:05 PM |
Metadata Editor The metadata editor (GeoNetwork-UI) has been available for production use since early 2025. This tool aims to simplify metadata entry, particularly in an OpenData context. Users are guided through a simple and clear process. The architectural choices of the GN-UI editor (pivot model, interface above APIs) make it compatible with more advanced use within GeoNetwork itself, with metadata editing being non-destructive of existing values. New features will be developed during the year, including multilingual support and templates. |
Laure-Hélène Bruneton - CampToCamp |
3:15 PM |
AI and LLM, Boost the Discoverability of Your Data Applications of LLM in the geospatial world and data platforms, particularly for the geOrchestra platform in the context of creating the DataGrandEst Chatbot. |

4:05 PM |
How to Feed Your IDG More Easily? Revamping the Datafeeder Module in geOrchestra Data ingestion is one of geOrchestra's weaknesses and needs an overhaul. What are our needs, and what solution should we implement? |
Florian Necas, Florent Berault |
4:25 PM |
Mutual Benefits of Integrating OpenStreetMap Data into geOrchestra Both based on PostgreSQL/PostGIS, OpenStreetMap (OSM) and geOrchestra together offer often overlooked potential. By integrating OSM into geOrchestra, you can access advanced ETL (Extract, Transform, Load) capabilities, create native download points, or benefit from filtering, analysis, and contribution tracking features that are not natively available in OSM web tools. In return, geOrchestra can leverage the richness of OSM data, automatically updated every minute if necessary, to enrich business data or cross-reference it. The presentation will illustrate several concrete examples of these synergies. |
Severin Menard - Les Libres Géographes |
4:45 PM |
Leveraging Open-Source Tools for Creating 3D Tiles in the Urban Environment The presentation covers the processes and open-source tools for building 3D Tiles for urban environments, including 3D data visualizations in MapStore and geOrchestra |
