Description

Technical Field

[0001] The present invention belongs to the technical field of marine information data visualization, and particularly relates to a visualization method, device and medium for marine hydrometeorological data. Background Art

[0002] With the continuous upgrading of observation technologies, various marine meteorological and hydrological data have been widely used, and at the same time, higher requirements have been put forward for their visualization processing. Visualization technology is an important means to image marine hydrometeorological data. By converting data into images that are easy to understand and analyze through visualization, it can facilitate users to better understand the characteristics and laws of the data, so as to make better decisions and applications. At present, NetCDF, as a self-describing and platform-independent data format for scientific data, is widely used in the storage and exchange of marine meteorological data. The visualization technology based on NetCDF has gradually become one of the mainstream methods for marine meteorological data visualization. However, some existing open-source software, such as NCL, NCview, and GrADS, mostly use specific high-level languages or have certain requirements for the system, and the visualization effect is single. The extraction and application of data are not sufficient and opaque, making it difficult to meet people's needs for high-quality visualization and application of data. Bathymetric information is of great significance for navigation, marine resource exploration, marine environmental management, etc.

[0003] For this reason, a visualization method, device and medium for marine hydrometeorological data with the publication number of "CN116912441A" includes: obtaining first marine hydrometeorological data and second marine hydrometeorological data; extracting information from the first marine hydrometeorological data to obtain key variable information of marine hydrometeorology; performing format conversion on the key variable information of marine hydrometeorology to obtain a variable information file, and further obtaining a first visualization model; extracting the bathymetric information of the second marine hydrometeorological data, and obtaining a second visualization model according to the bathymetric information; performing large-scale visualization and three-dimensional display on the marine hydrometeorological information according to the first visualization model, and performing 2.5D display on the seabed geomorphic information according to the second visualization model. The present invention can make full use of multi-source format marine hydrometeorological data, extract and apply characteristic variables, and display marine meteorological information and seabed geomorphic information through two-dimensional or three-dimensional visualization display methods.

[0004] However, for the above visualization method, device, and medium for ocean hydro-meteorological data, although information extraction is performed on the first ocean hydro-meteorological data to obtain key variable information of ocean hydro-meteorology, there are still the following obvious defects in the use process: However, in the process of obtaining information, since the data is directly obtained without prior storage and backup processing of the data, it is easy to have the problem of data information loss in obtaining ocean hydro-meteorological data, resulting in the re-acquisition of ocean hydro-meteorological data.
