Assessing seasonal vegetation change in coastal wetlands with airborne remote sensing: an outline methodology

摘要: Airborne remote sensing offers high-density, spatially-averaged synoptic samples of radiation reflected from a surface which can be used to infer ecological processes and community composition. Unfortunately, the cost overheads in terms time resources, scheduling constraints when deriving quantitative information have limited its use operational monitoring programs. When changes related phenomenon under investigation are large, only minimal low-cost processing is required identify ecosystem modification if high frequency multi-temporal imagery combined with expert knowledge. This methodology likely particular value coastal environments where access for conventional measurements restricted sensitive tidal wetlands may provide an early indicator changing natural and/or human impact. Regularly acquired airborne remotely sensed has been reconnaissance study map seasonal vegetation patterns on intertidal surfaces back barrier North Norfolk coast, England, U.K. The development system zone management discussed.
