A remote sensing survey was conceived to assess the relevance and appropriateness of a low-costing imaging spectrometry system, CASI (Compact Airborne Spectrographic Imager) applied as an airborne tool for coastal water assessment of Loch Linnhe (Scotland, UK). The system is described and compared in detail with other conventional and operational remote sensing instruments based on published reports and general scientific literature. It became clear in the case of Loch Linnhe that an airborne platform is the only viable possibility for monitoring by remote sensing, due to both the low likelihood of cloud-free satellite data and the relatively small size of such a fiord system. A survey plan is proposed which accommodates the environmental, logistical and technological constraints deemed likely to emerge during the data acquisition period. This work encompassed the use of other ancillary instruments, namely two portable spectroradiometers (SPECTRON SE-590) and an airborne multispectral scanner (DAEDALUS 1268) to enable both the comparison and calibration in support of the main data source. The availability of sea-truth (collected for one week each month over a period of two months during 1991) was entirely the responsibility of the Scottish Office Agriculture and Fisheries Department (SOAFD) who generously made the data available to this project. Although this in situ data could not be gathered absolutely in concurrence with the survey flights, their careful use proved essential to the project. A methodology based on the tidal behaviour within the sea-loch is proposed, from which sea-truth is derived.
