The invention relates to the technical field of
data visualization, in particular to a fluid
data visualization method and
system based on space-time analysis, and the method comprises the following steps: obtaining the number, coordinate and deployment duration of each sampling point, collecting rainfall, temperature,
humidity and pressure, calculating credibility, eliminating low-credibility data, extracting a parameter
sequence analysis trend, and generating an abnormal grade
label. And constructing a trend offset factor group, identifying a high-offset variation grid, and generating a variation dynamic map sequence. According to the method, invalid or interference data is eliminated by using calculation of sampling credibility, an anomaly level
label set is constructed through comparison and classification of trend change indexes and adjacent space partitions, the anomaly description capability of space-time trend change is enhanced, and an abnormal region state is calibrated through double standards of trend inversion and anomaly density, so that the accuracy of the abnormal region state is improved. Potential abnormal variation areas are effectively captured, identification codes are given, and the abnormal recognition precision and the area positioning efficiency in the fluid
data visualization process are integrally improved.
