Data as data can be obtained.

The clipping processing unit may be configured to apply raster data corresponding to a mask area of preset mask information based on at least one interpolation point data calculated by the interpolation calculation unit, according to a specific clipping algorithm according to the raster data generation algorithm.

That is, due to the nature of the marine information, it is not necessary to use the entire raster data corresponding to the interpolated / calculated extended space area (space cell) in the coastline area divided into land and sea area. That is, it is preferable to divide the uninterested region and the region of interest by the boundary of the shoreline and to remove unnecessary regions.

The clipping processing unit includes preset mask information for recognizing the shoreline, and based on at least one interpolation point data, ie, raster data, calculated by the interpolation calculation unit, according to a clipping algorithm, Clipping processing can be performed on raster data corresponding to the mask area (coastline). Here, since the clipping algorithm may be implemented by adopting various existing clipping methods, a detailed description thereof will be omitted. Here, the mask information may be previously set / stored by the operator, or may be stored inferred / recognized through a specific shoreline recognition algorithm.

The interpolation calculation unit may be requested to calculate point data, and the clipping processing unit may be requested to perform a clipping process by applying different preset clipping factors corresponding to the first area and the second area.

That is, due to the nature of marine information, the artificial seawall is added to the sea area so that accurate marine information can be provided only when the various ecological conditions of the ocean are reflected. In other words, it is important to create and manage data that is adaptive to environmental changes added artificially.

The mother application unit identifies the first region and the second region divided by the predetermined specific boundary region according to a specific mosaic algorithm according to the raster data generation algorithm. In this case, the preset specific boundary area may be preset / stored by the operator. Alternatively, the mother application unit compares / analyzes the interpolation data and the measurement data corresponding to the sea area section during a specific prediction time according to the mosaic algorithm, and determines that an artificial change factor exists in the sea area section where the error range exceeds the threshold.
