Abstract

The embodiment of the invention provides a method and device for generating an inspection error spatial distribution diagram of ocean satellite data, and relates to the technical field of ocean engineering. The method comprises the following steps: performing space-time three-dimensional spline interpolation on inspection source data based on parameter information of marine satellite data to obtain reference data of the marine satellite data; calculating an observation error of the marine satellite data by utilizing the reference data; projecting the observation error on a preset space equal longitude and latitude grid generated by performing equal longitude and latitude network division based on ocean satellite data to obtain a projection result; calculating proportionality coefficients between the spatial distances on different latitudes and the longitude grids based on the earth curvature; and performing adjacent point interpolation by taking the proportionality coefficient as an interpolation window according to the projection result so as to fill the uncovered equal longitude and latitude grids in the projection result and generate a marine satellite inspection error spatial distribution map. Thus, the problem that the existing method cannot visually and accurately display the spatial distribution of the inspection error is solved.
