This invention discloses a method for constructing a comprehensive
transportation infrastructure spatial database based on multi-
source data, including the following steps: S1, collecting data on three types of
transportation infrastructure: highway,
water transport, and
aviation; S2, establishing a
data dictionary and
metadata standards based on specifications, and formulating a
database partitioning strategy and interface specifications; S3, standardizing attribute data,
satellite image data, and spatial vector data; S4, formulating a spatial data sharding strategy based on
geographic regions, building a full-text index and spatial
index system, and optimizing storage and query; S5, using MySQL, PostGIS, MongoDB, ElasticSearch, and K-V storage for
collaborative management; S6, designing expansion mechanisms at the storage, retrieval, and computing
layers; and S7, establishing a unified retrieval platform based on the
database, integrating raster and vector data, and supporting
spatial visualization and semantic retrieval. This invention enhances the ability to integrate, retrieve, and expand
transportation infrastructure data, and is suitable for the construction of a comprehensive transportation information platform.
