The invention discloses a
data compression method suitable for marine meteorological
visualization, which comprises the following steps of: step 1, reading
original data, namely reading the original marine meteorological data, and extracting a time slice and meteorological element data; step 2, meteorological data preprocessing: performing integer
processing on the
original data; step 3, removingcorrelation of the meteorological data; and step 4, compressing code
stream data and performing entropy coding on the meteorological data subjected to
decorrelation. Compared with an existing
data compression mode, the method is more suitable for compressing the data visually displayed by the marine
meteorology, the characteristics of high real-time requirement and large data volume of traditionalmeteorological data are fully considered, the marine meteorological data can be compressed, the data
repeatability is reduced, redundant labels are removed, and the data size is reduced to the maximum extent. The method specifically comprises the steps that 1,
original data can be read; 2, truncating is performed according to the observation precision of the elements; and 3, the correlation of the meteorological data is removed; and 4, the marine meteorological
data compression ratio is increased.
