A Prototype Metadata Tool for Land Use Change and Impact Models - a Case Study in Regional Victoria, Australia

The use of models to infer or predict changes and impacts in natural resources and environmental systems is a fundamental research activity around the world. A recent audit of such modelling activities in eastern Australia uncovered a plethora of models in use and a number of instances where models were implemented across various groups and agencies. Often the active parties were unaware of each others research. The preparation of data and development of model parameters to support deployment of a model can take considerable effort and this can often be leveraged by subsequent research. Additionally, previous modelling when accessible may reduce expenses and inform by lessons of experience the selection of models and approaches to their future implementation. Addressing these research needs is the subject of this article. A prototype tool for storing and managing model metadata has been developed that extends the utility of the more traditional model register allowing storage of details associated with each instance of a model run. A non-standard approach has been taken to enable efficient registration of the spatial context for model runs. The overall approach taken has implications for the development of Spatial Data Infrastructures (SDI), model automation and e-science.
