Dynartio
Who we are
We are a small company based in Angoulême, France, and founded by :
- Benoit Ribon (
Ben_Dynartio (ben10dynartio on osm, edits, contrib, heatmap, chngset com.)) - Marina Petkova (map-dynartio (on osm, edits, contrib, heatmap, chngset com.)).
We created Dynartio in early 2021 from the research works of our co-founder Benoit in geography, spatial planning, and territorial metabolism.
We use territorial data to study how resources and infrastructures are organized, and we build tools to make these analyses useful for local projects. In particular, we focus on the territorial metabolism approach, which looks at the flows and resources a territory needs to function, such as energy, raw materials, food, mobility, waste, or carbon.
Some of our studies require mapping or statistical analysis, and whenever possible we turn to OpenStreetMap. We are both heavy users and active contributors to OSM and its database.
What we do
We're particularly specilised in :
- Circular economy studies at different territorial levels ;
- Tool-developping and setting up territorial observatories on topics related to flow- and ressource management.
- Mapping with OpenStreetMap.
Our main topics of interest
- Spatial analysis, with a focus on mobility.
- Territorial knowledge chain, with a focus on data organisation and data sharing.
- Industrial and territorial ecology, with a focus on fostering ressource mutualisation between local actors, circular use of materials, waste reduction.
We've used OSM for some of our studies, as listed below. In return, we contribute to further enriching its database.
- KartoDistrict (2020) : creation of thematic atlases with maps on transport, demographics, land use, and other topics for the Strasbourg-Ortenau Eurodistrict and organisation of an OSM contribution challenge (available in French and German).
- Co2Inno (2022-2025) : Analysis of electric vehicle charging stations as part of the Franco-German-Swiss cross-border research project CO2InnO (available in French, English, German).
- MapYourGrid (2025-, ongoing) : Participation in the international project MapYourGrid that aims to map High Voltage electricity transmission networks worldwide (available in English). Our contributions include :
- Mapping of energy infrastructures on OSM ;
- Updating and analysis of OSM data on energy interconnectors ;
- Contributing to Wiki documentation on mapping guidelines for power infrastructure.
- Cycling networks (2023-2024) : Photomapping with Panoramax and OSM of cycling networks in Angoulême and Saintes (France), (available in French).
- Training new OpenStreetMap contributors (e.g. Vélo d’Vie Cognac, Commune de Sainte-Soulle).
Tools
Sinamet is an open-source Python library that our co-founders have been developing since 2018. It builds on the territorial metabolism approach and serves as the foundation for territorial observatories on themes such as energy, mobility, food, and material reuse, helping local authorities model and understand how resources are organized and used.
Sinamet uses scientific methods in territorial analysis and circular economy. It helps connect datasets that are often fragmented in order to reveal links between public policies and socio-economic and ecological impacts (for example, how transport policies influence local attractiveness, or how reuse initiatives contribute to socio-economic potential).
