DESCRIPTION:IGN (French National Map Agency) and its partners are launching
  the JUNN project : A dynamic 3D digital replica of the territory with o
 nline services to interact with (visualization\, immersive navigation\, si
 mulation). A tool that aims to federate data\, technologies\, communities 
 and existing initiatives to collectively gain efficiency for the ecologica
 l transition.​ \n\nThis digital twin of France and its territories is a 
 tool-based approach\, supported by a consortium of public and private play
 ers\, enabling the development of a common Open-Source architecture built 
 in support of identified business usescases. \n\nObjectives are multiples:
   \n* Reducing the cost of local initiatives and facilitate their replicat
 ion in other areas\, \n* Establishing a framework for interoperability and
  interface between different projects \n* Setting up a science platform to
  facilitate the development of technological advances from R&D\, \n* Build
 ing an ecosystem of services and business applications with high added val
 ue \n\nThe project will include 3D data production with 3D mesh data and C
 ityGML LOD 2.2 data. The 3D meshes will be generated using the Wasure soft
 ware (https://github.com/lcaraffa/sparkling-wasure)\, which was developed 
 based on research conducted by the Lastig research laboratory. This softwa
 re will be further refined during the project\, in collaboration with INRI
 A and GeometryFactory. \n\nSome of the CityGML data will also be produced 
 by the IGN. Initial tests using the Open-Source Roofer software (https://g
 ithub.com/3DBAG/roofer) have yielded promising results (https://batiment3d
 .ign.fr/) regarding what the Digital Twin data might look like. \n\nThis p
 latform is intended to serve as a hub for scientific research\, where it w
 ill be possible to connect simulators that have access to the platform’s
  extensive dataset. This will be the case\, for example\, with the ICI pro
 ject (https://x-ngilet.gitlabpages.inria.fr/html_covici/index.html)\, whic
 h offers models of epidemic spread and whose access to the data will impro
 ve predictions \n\nFor visualization\, we will use the open-source renderi
 ng engine iTowns (https://www.itowns-project.org/)\, to which IGN is a maj
 or contributor. Already high-performing\, the close collaboration between 
 the Digital Twin team and the iTowns development team will ensure that thi
 s tool is fully compatible with what we will be offering. \n\nWe are propo
 sing this presentation to give the OSGeo community an overview of the proj
 ect. This presentation will introduce the various open-source software com
 ponents we will be using\, some of which we will be enhancing (Wasure\, iT
 owns\, Rok4\, Roofer\, etc.).
