Integration of heterogeneous web-GIS land management platform using model-view-controller design pattern

Remote sensing technology has been widely deployed to detect land change during the past decade. In Taiwan, a number of different land use / land cover change detection systems have been developed to assist in land use management and administrations and to assist in investigations. This paper details our application of the Model-View-Controller (MVC) design pattern to facilitate access to heterogeneous land management systems via the national "Integration of Land-Use Monitoring" platform. The platform integrates web-based Geographic Information System (GIS) and Management Information System (MIS) to provide a unified online environment for land change reporting and investigation by different departments and agencies with different policies and requirements. Using the MVC architecture, these platforms are developed in an independently partitioned manner, allowing developers to separate user interfaces from user interaction, while keeping the whole system flexible and stable. On the whole, the Integration of Land-use Monitoring platform with its in MVC infrastructure is partitioned such that different backend processes can be changed without modifying other processes and applications, thus alleviating impact from the unpredictable and complex environmental nature of heterogeneous systems.
