Notes:
Linking is defined as merely passing input and output between a GIS and a model, combining is defined as automatic data exchange and GIS tool functions, and integrating is defined as embedding a model in a GIS or vice versa. Due to differences in research objectives, spatial and temporal scales, data sources or formats, and the natural processes being modeled, there is no universal approach for interfacing. Because of the detailed input requirements for agronomic models, expanding the models from a point-based application to a spatial application can greatly increase the volume of input data. This review suggests that a major challenge in interfacing GIS to models lies in developing systems that handle spatial processes by implying interactions among spatial units. Moreover, extensive data requirements must be satisfied, while also ensuring data quality control.
