Here is the first open version of my #MERN application for a light and compact management of 3D city models https://t.co/o35XcyZF8I #CityJSON @Geomatics_Unit #opensource #geomatics #GIS

I gave a small talk on our "academic viewpoint" on #SmartCities and #DigitalTwins at the @CIRB_CIBG Presentation is available at

Spent 2 hours at the @EuroSDR Workshop with #NMCA defining a trend and/or common definition of what a Digital Twin is: impossible #Geomatics #Interoperability #research

Big improvements! It seems we need to upgrade our processes and software. A paper will surely follow on our developments thanks to these advances. #CityGML #CityJSON #Geomatics @Geomatics_Unit

Excited to announce the publication of the #CityGML v3.0 Conceptual Model Standard. CityGML defines a semantic information model for 3D objects and models that can be used by many different applications - making #3D city models much more cost-effective https://t.co/Zc0vv3yop5

Have you met its simplified document-oriented schema? https://t.co/davyZwd3Gf #CityGML #Geomatics #3dcitymodels

I presented this afternoon an extension of #CityJSON for the support of #PointCloud following the #CityGML 3.0 at @isprs XXIV Congress Here is the presentation : https://t.co/a7SFy3sPtJ #Geomatics #GIS #3dmodelling #city

Coming soon DOI:10.1111/tgis.12807 #CityJSON #CityGML #3DCityModel #Schema #Geomatics

Working on an extension to #CityJSON for the #3DPointCloud following the 3.0 #CityGML specs Looks promising isnt it? #geomatics #3dcitymodel

Il y a quelques mois, nous réalisions cette carte pour la collecte des tests covid-19 de l'ULiège dans les maisons de repos wallonnes. Tous les traitements ont été réalisés avec de l'open source! Plus d'info ici -> https://t.co/ZUTfRqD7Vd #geomatics #covid19

I have released the last version of my application Measur3D v0.3.0 ! This new version comes with improvements : OGC API - Features, Swagger, GeometryInstances, etc. Code can be found at : https://t.co/o35XcyZF8I #CityJSON #Geomatics #GIS #3DCityModel #CityGML

This is a #3dcitymodel, formatted in #CityGML 3.0, encoded in an #CityJSON 2.0 extension, stored on #MongoDB, streamed over the web using #OGC API - Features (the "WFS3" standard). Stay tuned for more ! #Geomatics #gis #webdevelopment

Explaining CityGML 3.0 and CityJSON in 10 minutes. Impossible. #BeGeo2020 #geomatics #gis

Last week, I presented the new #3DCityModel Standard of the @opengeospatial family at the AM/FM Belux #Webinar. We spoke about #CityGML 3.0, #CityJSON, #SemanticWeb and #OGCAPI Here is my presentation: https://t.co/JLn0ioLfZX #geomatics #GIS

Last week, we exchanged with @tudelft3d at the #3DTalks on the work of the @Geomatics_Unit on #CityJSON. Here is my presentation : https://t.co/SrDE3VE2QO #3DCityModel #Geomatics #SmartCities #Research

With @PouxPointCloud and @RolandBillen, we propose a solution for the building generation of #CityJSON models from a fully unsupervised #pointcloud segmentation. Have a look at the paper! https://t.co/VmNeW5jcy7 #geomatics #Research

The lockdown's coming to an end, it's gonna be time to take my head outside. #3DCityModel #SmartCity #CityJSON #geomatics #gis #geospatial #1or2month

Another application of the #digitaltwins : walk in a model of our streets rather than in them in this hard time (Here the 27k buildings of Liège, Belgium) #cityjson #geomatics #COVID2019 #StayHomeSaveLives @Geomatics_Unit

8 years after https://t.co/ZRSBFmGAH7 the OGC standard for 3D City Modelling #CityGML 3.0 follows our recommendations https://t.co/PwcMpd1Dsh #Geomatics @universiteliege @geomatics_unit @opengeospatial
