Ocelet : modelling language and platform

Software and digital applications Natural resources and territories
The Ocelet programming language and its associated software environment (Ocelet Modelling Platform) enable modelling and simulating spatial and landscape dynamics in order to assess the combined effects of planned and/or observed spatial changes.

Support for decision-making tools for land and landscape management

While the description of interacting factors in spatial dynamics simulation models remains a real challenge for modellers, R&D project stakeholders and regional decision-makers require visual outputs and interactive dashboards that are often lacking.

Ocelet is a programming language specifically designed to help developing decision-support tools in the fields of environment, agriculture, and epidemiology.

It integrates different forms of spatial representation within a single model in order to simulate spatial dynamics scenarios. This makes it an excellent tool for studying landscape changes and environmental issues.

Highly modular scenarios for better regional management

Through the concept of interaction graphs, Ocelet enables the integration of spatial processes with diverse representations, while promoting a systemic and spatialized understanding of the processes at play in a territory or landscape.

Ocelet thus provides the means to work at multiple spatial scales, integrate various forms of geographic information, and produce dynamic maps representing the landscape changes :

  • Integrates a large number of influencing factors into a spatial dynamics model ;
  • Is well suited for management support applications ;
  • Allows for the evaluation of development scenarios.

Markets and applications

Ocelet is an excellent tool for highlighting :

  • Landscape evolution : the dynamics of a coastline, for example ;
  • Environmental issues such as land use change dynamics, or the spatial spread of invasive plants, pathogens, or insect pests ;
  • Transportation and logistics issues on networks.

It is therefore aimed at a wide range of potential users :

  • Planners, Consulting firms, technical services ;
  • Territorial stakeholders and public decision-makers ;
  • Scientific project managers, researchers.

How can Ocelet be implemented?

Ocelet developers support you through :

  • Expertise in integrating spatial dynamics models in projects supporting territorial management ;
  • Support in developing simulation models ;
  • Training in the use of the language.
The research team
Within the TETIS Joint Research Unit, the Diamant (Territorial diagnosis and foresight through modelling and spatial analysis) team develops tools and methods to produce spatialized knowledge on the processes driving current environmental and societal transformations, particularly in forms that can be used by local stakeholders.
