Bathymetric data in Lakes & Rivers
Importance
A large number of development relies on the accurate bathymetric data in the world. Nevertheless, thousands lakes and rivers completely do not have accurate bathymetric data. Consequently, the elevant developments are delayed or terminated.
Desired Bathymetric Data
People in the world have been exploring the method of finding the accurate bathymetric data for a long time. Unfortunately, so far the effective manners of finding absolute depths of water body have not been found at all, therefore, NOAA is detecting Great Lakes and seacoast using laser which is not only very expensive and time consuming but also exists large error caused by power or saturation broadening in the process of detecting water body using Lidar. Those error must be maximally cut off. However, such modification fails to be performed by themselves: the measured data.
Crucial Discovery
One great technique consisting in our techniques is able to directly detect the absolute depths of water body in lakes and rivers including seacoast. In fact, the bathymetric data have already existed in the DEM when it was generated by SAR (Synthetic Aperture Radar) installed in the platform such as shuttle and satellites, and eventually formed by two separated Interferometeric radar imageries at the same geographical location. However, such an important phenomenon and hidden bathymetric data have completely been ignored by people and important organizations such as NASA, USGS,NOAA and ESA.
This discovery is full of dramatic practical significances and has revolutionarily solved a very difficult problem whose resolution has been sought for a long term worldly. The initial report of such a vital discovery being described by Dr. Carl Jiang has been shown in the published paper[1].
