Species Distribution Modeling Alexandre Copertino Jardim Antonio Miguel Vieira Monteiro Karla Donato Fook Lúbia Vinhas Silvana Amaral Scientific Workshop In Geoinformatics, INPE, 18 February 2009

2 Context  The project involves three institutions: CRIA (Reference Center on Environmental Information), Poli (Escola Politécnica/ USP), and INPE.  openModeller’s project goal is to develop a framework to facilitate the work of scientists in predictive modeling of species distribution:  develop a component-based modeling framework with reusable modules compliant with web services technology  enable the existence of multiple interfaces (web, desktop, command line, web service)  facilitate access to distributed biological and environmental data networks ...

7 Environmental Data Alexandre Jardim in a Master student, working on creating a Web Environmental Catalogue Service: - an ontology for environmental data in the domain of SDM - a WS that identifies data sources exporting data as WCS and that makes a mapping between its metadata and the SDM ontoloy - a client interface to the WECS and openModeller - evaluate the WCS specification for the SDM domain

Web Client applications Researcher WBCMS Web Biodiversity Collaborative Modelling Services Client Applications Model instances Catalogue Karla Fook in her phD work proposes an approach for sharing species distribution modeling on Web Publish modeling experiments and their provenance, to make it available into catalogues, and to enable researchers to perform new models based in catalogued model instances Sharing modeling experience

9 The model instance includes data and metadata about the model, its generation process, and experiment results. Which species are being modelled? Where does the data come from? Which environmental variables and algorithms are being used? If I have a question, how can I look for similar results? Model Instance
