A Correction of the GEBCO30 Bathymetric Data in the Andaman Sea
Abstract
The general bathymetric data (the GEneral Bathymetric Chart of the Oceans 30 arc-second; GEBCO30) with the resolution of 0.5 nautical miles from 3 areas in the Andaman Sea in the area of Thailand was corrected by comparison with the depth data that was surveyed by ship-line sounding and distributed by the Hydrographic Department, the Royal Thai Navy (Navigation charts; NC) for 17 charts in total. The research is the discrepancy analysis of the GEBCO30 data following the standard of IHO (2008) and correction of GEBCO30 data by using scripts of GMT (Generic Mapping Tools) programming. The result shows that the corrected GEBCO30 data and GEBCO30 data in the Andaman Sea in the area of Thailand of 133,636 data shows depth ranging between (-780)-(0) meters and found that 96.25 % of data has discrepancy from NC data following IHO (2008). If the fine data is required, grids size of the data could be adjusted by resampling grids. The data from this research can be used as the input data into the mathematical model for study the water circulation in the Andaman Sea that required the corrected data because of confident of model result.
Keywords : the Andaman Sea, GEBCO30arc-second, ship-line sounding, bathymetric data
