What is The Cost-effectiveness of Remote Sensing for Tropical Coastal Resources Assessment and Management about?

Although coastal habitat mapping is expensive, remote sensing is a more cost-effective technique than alternative field-survey methods (where effectiveness is defined as overall map accuracy). Satellite imagery is suitable for coarse detail habitat mapping where overall accuracies of c. 70% can be achieved but is inadequate for fine detail mapping, achieving c. 40% accuracy. Four types of cost are encountered when undertaking remote sensing: (1) set-up costs, (2) field survey costs, (3) image acquisition costs and (4) the time spent on analysis of field data and processing imagery. The largest of these are set-up costs such as the acquisition of hardware and software which may comprise 48-78% of the total cost of the project depending on specific objectives. For coarse-detail habitat mapping with satellite imagery, the second highest cost is field survey which can account for c. 20% of total costs and >80% of total costs if a remote sensing facility already exists. Field survey is a vital component of any habitat mapping programme and may constitute c. 70% of project duration. For mapping small coastal areas (<60 km in any direction) in coarse detail, SPOT XS is the most cost-effec
