I think you are looking for seafloor depth information. Such information referred to as bathymetry is available from Gebco. The data is derived from satellite scan and are in .nc format and unless you are familiar with using GIS software, you will not be able to read/view it.
I can generate these bathymetry nautical charts for you for the whole of the Gulf of Thailand if you wish or some island which you want.
I normally load this in my Garmin gps as a Kmz file (Google Earth format) which can also be viewed on Google Earth in your laptop.
You may also wish to check out 'OpenCPN', a pc based free chartplotter which you can connect to your gps and navigate with this
