Shrinkage city data collection and arrangement method and system based on multiple dimensions

The invention relates to the technical field of data clustering compression, in particular to a multi-dimension-based shrinkage city data collection and arrangement method and system. According to the method, the contraction trend of each piece of feature time series data is obtained according to the distribution condition of the feature time series data at each moment in the city index and the distribution condition of the feature time series data in different city indexes at the moment; the method comprises the following steps: acquiring a feature cluster, acquiring a compression demand of each cluster according to association among various urban indexes in the feature cluster and a contraction trend and distribution aggregation of feature time series data, and analyzing the distance between each feature cluster and other clusters, the compression demand and the contraction trend to analyze the mergibility. And carrying out compression storage on the obtained final clustering result. According to the method
