1. A data processing system, comprising:
one or more memories;
one or more network interfaces; and
one or more processors coupled to the one or more memories and the one or more network interfaces, the one or more processors, either alone or in combination, configured to:
store, in the one or more memories, an integrated hierarchical and spatial database comprising all geospatial units of each geographical entity stored within a plurality of datasets from one or more data publishers, wherein the plurality of datasets is arranged according to a corresponding plurality of different hierarchies, wherein the integrated hierarchical and spatial database stores integrated hierarchical and spatial relationship information for each geospatial unit with respect to other geospatial units of each geographical entity stored within the plurality of datasets according to the plurality of different hierarchies, wherein integration of the plurality of different hierarchies within the integrated hierarchical and spatial database indicates relationships between different types of geospatial units across the plurality of different hierarchies;
receive, via the one or more network interfaces, a query to the integrated hierarchical and spatial database, wherein the query specifies a value for a geographic place, a value for a geospatial unit, a value for a time period, a value for a search topic, or any combination thereof to be applied across the one or more data publishers, the plurality of datasets, and the plurality of different hierarchies; and
transmit, via the one or more network interfaces, a response to the query, wherein the response includes one or more search results associated with different geospatial units that are linked together across the one or more data publishers, the plurality of datasets, the plurality of different hierarchies, or any combination thereof based on the relationships between the different types of geospatial units across the plurality of hierarchies stored in the integrated hierarchical and spatial database.
