Sea-land-river integrated map service system

The invention provides a sea-land-river integrated map service system. According to the sea-land-river integrated map service system, a sea-land-river multi-source data access module accesses geographic space element data, ship dynamic data and navigation related data through a user front end; the heterogeneous data standardization and normalization module performs automatic standardization and normalization treatment on the heterogeneous geographic space element data; the sea-land-river integrated data resource platform stores data, updates dynamic data in time, constructs a plurality of databases, and provides application services corresponding to the databases when each theme database is accessed; the Internet map service module realizes communication between the sea-land-river integrated data resource platform and the user front end; and the video enhancement monitoring and early warning module provides video enhancement monitoring and early warning service of the key water area when the key water area sa
