Simulation of spatial dynamics using Ocelet

Computer science, GIS and modeling
The TETIS research unit has developed a spatial dynamics modelling and simulation platform named Ocelet. This software has been in use for already several years on a diversity of research projects within our research unit. The version 2 is available on the www.ocelet.org web site since February 2018. Potential scope of application include: land use planning and management, coastal dynamics, spatial epidemiology, dissemination processes (of an invasive species for example), or production of animated maps for teaching purposes

Objectives

* Study a spatial dynamic process and formalize it into Ocelet concepts

* Be familiar with the usage of the Ocelet modelling platform

* Write programs using the Ocelet language

* Produce animated maps within QGIS and Google Earth

* Simulate common modelling situations such as spatial diffusion and land cover change

Audience

Researchers, research students, engineers, who need to model and simulate landscape changes or spatial and dynamic processes.

Language

Trainers

Experts Cirad, UMR TETIS : Pascal Degenne et Danny Lo Seen

Prerequisites

A good knowledge and understanding of GIS concepts and software (ArcView, ArcGIS, QGIS, …)

A previous experience and practice of a programming language (any of them, including R or Matlab) is desirable.

Use your own laptop computer (Linux or Windows). The software used during training will be supplied.

Teaching materials

Teaching methods:

A mix of academic presentations and practical work

Evaluation methods :

it is not the questionnaire at the end of the training but an evaluation of knowledge and skills upstream, downstream, or a cold testing training (Positioning tests, knowledge quiz, exercises, tutorials, case studies ...)

Exercises and case studies
