This invention relates to the field of multi-
source data processing technology, and more particularly to a method for real-
time data calculation of
water resources bulletins based on the fusion of multi-source heterogeneous data. The method includes the following steps: constructing a pluggable and high-
concurrency unified
data access gateway, configuring multiple types of adapters within the unified
data access gateway; completing the access and extraction of multi-source heterogeneous data through each adapter, adding spatiotemporal tags and
metadata tags to the data extracted by the unified
data access gateway to obtain an initial data asset catalog; establishing a multi-dimensional
data quality assessment matrix, automating and standardizing the data in the initial data asset catalog, and outputting standardized
water resources data. This invention, by constructing a unified access gateway, a programmable computing engine, and a spatiotemporal knowledge
fusion system, achieves full-process
automation of
data processing, multi-source fusion, and dynamic generation of bulletins, thereby improving the
processing efficiency, timeliness, and availability of multi-source heterogeneous
water resources data.
