A knowledge induction process is formulated to select optimal decision rules with a minimal set of features necessary and sufficient for a remote sensing classification task. The approach first converts a real-valued or integer-valued decision system into an interval-valued information system. A knowledge induction procedure is then formulated to discover all classification rules hidden in the information system. Two real-life applications are made to verify and substantiate the conceptual arguments. It demonstrates that the proposed approach can effectively discover in remotely sensed data the optimal spectral bands and optimal rule set for a classification task. It is also capable of unraveling critical spectral band(s) discerning certain classes. The framework paves the road for data mining in mixed spatial databases consisting of qualitative and quantitative data.

Ecotourism planning using multiple criteria evaluation with GIS / T. Fung in Geocarto international, vol 22 n° 2 (June - August 2007)

Recently, ecotourism has flourished and attracts ecotourists who visit the ecological and cultural resources of the rural landscape, country parks and marine parks. Yan Chau Tong, also known as 'Double Haven', is remote from the urban centre, which helps preserve its natural flavour and cultural heritages such as Hakka walled villages. It is noted as an important site for developing ecotourist activities. A symbiosis of humans and nature cannot be achieved without a sound planning and zoning scheme. This paper investigates the use of IKONOS imagery and a geographic information system for rational planning of ecotourist activities and conservation measures. Through image classification of IKONOS and integrated with ecological data, essential habitats can be mapped and a spatial database is established. Suitable sites for recreational activities (including camping, heritage visiting, hiking and snorkelling) and important ecological habitats can both be identified using multiple criteria evaluation techniques. The use of a multiple objective land allocation model helps resolve conflict between recreation and conservation. Sites are generally identified as (a) those where conservation or recreation should receive the highest priority; (b) those that can be treated as additional recreation or conservation sites; and (c) conflict areas that can serve both purposes. The result can assist in planning land resources for ecotourism to satisfy both objectives and attain sustainability in the area.
