Comparison of vegetation indices (soil-line based indices) for mangrove vegetation mapping at Kelantan delta

Abstract

The study of companson five soil-line based vegetation indices for mangrove mapping was carried out at Kelantan Delta. The aim of this research is to identify mangrove forest type based on soil-related vegetation indices which were Perpendicular Vegetation Index (PVI), Soil-adjusted Vegetation Index (SAVI), Optimized Soil-adjusted Vegetation Index (OSAVI), Transformed Soil-adjusted Vegetation Index (TSA VI) and Modified Soil-adjusted Vegetation Index (MSAVI) approach derives from Landsat Thematic Mapper (TM) 2000. Soil-line based VI which include soil slope, intercept and parameter were introduced in mangrove mapping in order to remove the soil background such as humus, root and rock which can alter the vegetation readings.
