| Abstract | This study mainly focuses to develop a methodology that utilizes satellite digital images for monit01ing changes in coastal mo1phology in the Songkhla lagoon inlet and its vicinity, in the Thailand southern peninsula, with applications of satellite remote sensing and geographic inf01mation systems. In an attempt to extract shoreline info1mation, the mathematical morphology was employed. A GIS approach was used for integrating digital image data with other geodata such as navigation maps and quantitative analysis of changes in coastal sedimentation. The study showed that due to the presence of a jetty the coastline changes were obse1ved on two sides, namely coastline erosion occuned on the n01th side and at the same time the accretion occuned on the south side. Based on the result of the 19 years' petiod of the study (1975 - 1994), the trend of change will continue to impact the coastal environment at a rapid rate of erosion/accretion. It has been found that high resolution satellite data is ve1y effective for monito1ing change in coastal sedimentation, but still the spatial resolution of satellite used in this study limits to monitor the change for sh01t te1m. Also the GIS has been found to be ve1y effective in analyzing shoreline change quantitatively by overlaying multi-temporal shoreline maps. The research shows that mathematical morphology approach can be used to extract linear inf01mation such as shoreline from satellite image effectively. |
