Strategies for Open and Permanent Access to Scientific Information in Latin America: Focus on Health and Environmental Information for Sustainable Development

openModeller Desktop - A new approach to niche modelling, Tim Sutton, Renato De Giovanni, CRIA

The openModeller project ( provides a set of software libraries and applications for carrying out ecological niche modelling. Ecological niche modelling is based on the premise that we can compute the preferred range of environmental preferences for an organism by extracting environmental values (temperature, precipitation etc) at points where the organism has been recorded (e.g. herbarium collections) and then extrapolate these preferences into a generic model that describes the areas where the organism is probably able to survive.

Various software packages already exist for this purpose - each one presenting a new learning curve for the user and usually targeted to a single algorithm. Comparison between algorithms becomes difficult when models are produced by different software applications.

openModeller Desktop enables researchers to create, compare, and analyze fundamental niche models produced with different algorithms using a single application. openModeller Desktop is one of the available interfaces on top of the openModeller library.

Features include:

In this presentation a visual tour of the openModeller Desktop application will be given.
