Land use change explorer : a tool for geographic knowledge discovery

This paper describes a tool prototype named as Land Use Change Explorer, which was developed to allow different users to generate "GKD process tracking” (discovering land use change patterns) and “GKD process steering" (understanding uncertainty in these patterns as the process unfolds). The Land Use Change Explorer was implemented based on the GeoInsignt approach, previously described in Wachowicz (2001). From a system perspective, the prototype allows users to perform a series of steps of a GKD process, from selecting appropriate data sets and proper visual representations to visualizing land use change information and data mining results. From a user perspective, the abductive mode of reasoning is supported by distinguishing two types of users. They represent two stakeholders: an agricultural policy maker and an urban planner.
