(before result and analysis)
The overall objective was to use GIS as decision support tools for sanitary landfill siting
- This research produce satisfactory result
- Helps Sandakan Municipal Council to make
better decision (presented 14/08/2002
The specific objective was to use Constraint Mapping Technique (CMT) as recommended by the Environment Department to reduce search area for possible landfill siting and to test this technique in one of the LA.
- CMT identifies 6 Potential Search Area (total Sandakan District - 218,200ha, PSA – 57,273ha, from GAM – 8,503ha)
The final product was an established method of landfill siting process which would be useful for Local Authorities and Planning Department.
- Established and tested methodology
on process, data handling, disseminations of information
Demand for sanitary landfills will never end and will be there indefinitely because all other options still produce waste
(John Maxwell, 1997).
