FIDW algorithm for temperature and salinity image interpolation in sub-surface ocean

Maximizing the efficiency of image temperature and salinity image interpolation in subsurface ocean is the key to solve the dynamic information services in fishing conditions.IDW can observe the marine section of two-dimensional interpolation points,but the common IDW algorithm is less efficient.FIDW interpolation method is used to improve efficiency.It achieves fast image interpolation in the case of using the same formula.The interpolation image is verified by measured data.The result shows that error range can meet the needs of analysis and applications in fisheries.
