Abstract: PURPOSE: An interpolation method using an inverse distance weighted value is provided to prevent an interpolation error by adjusting an inverse distance weighted value of a separate distance between a reference grid line and a data point. CONSTITUTION: A separate distance between data points located within an effective radius from a reference grid line out of several grid lines (S10). An inverse distance weighted value with respect to the separate distance is respectively calculated (S20). A weighted sum is calculated by summing up the inverse distance weighted values (S30). Water depth of each data point applying the inverse distance weighted value is summed (S40). An optimal water depth value of the reference grid line is calculated using the weighted sum and the water depth sum (S50). [Reference numerals] (S10) Step of calculating distance; (S20) Step of calculating weighted values; (S30) Step of calculating the sum of weighted values; (S40) Step of calculating the sum of water depth values; (S50) Step of calculating an optimal water depth value
