| Abstract | Recent years have witnessed a growth in the quantity and quality of free and open source software (FOSS) tools for use in environmental data analysis and modeling. Such developments have significant potential to aid environmental managers, scientists and stakeholders in both developed and developing countries by reducing initial acquisition costs and providing a level of transparency that is often critical for regulatory, administrative, and on-going code development purposes. While commercial off-the-shelf (COTS) environmental software tools play an important role in the environmental community, the concept of FOSS continues to attract interest among software developers, sponsors and end-users alike. |
