Description 725-730
Present study took into
account the relationship between surface soil moisture of intertidal zone and
its spectral reflectance and the relationship between surface soil moisture and
the relative elevation of intertidal zone to extract ‘ridges’. It can represent
the main morphological character of radial sand ridges, and find specific
spectral bands to diagnose much ‘drier’ points of sand ridges in low tidal
condition. This could be considered as much higher points of sand

ridges. On that basis
the ridges’ changes were also discussed in this paper. Based on spectral
analysis and comparison between extracted sand ridges and field measured
elevation, the results demonstrated that the sensitive band centered at 2 224
nm has an excellent potential to extract sand ridges, furthermore the extracted
sand ridges matched with field measured elevation accurately.
