Abstract

The invention provides a mobile navigation and positioning system for water information. The mobile navigation and positioning system comprises an information navigation and positioning module, a spatial analysis module, a map control browsing module, a spatial query module, a special query module, a mobile office module, and a system management and configuration module, wherein the information navigation and positioning module comprises a GPS (Global Positioning System) positioning submodule, a real-time tracking submodule, a track playback submodule and a satellite sky view display submodule. By adopting a modular design mode, the system is improved in multiple angles of spatial data storage format, spatial data storage mode and the like, and the system has the advantage that the seeking speed of the water information is high.

Description

technical field [0001] The invention relates to a positioning system, in particular to a water conservancy information mobile navigation and positioning system. Background technique [0002] With the rapid development of computer technology, Global Positioning System (GPS) and Geographic Information System (GIS) have been widely valued and applied in all walks of life. Visualization, integration and integration on GIS can dynamically track targets and display geographic locations on maps in real time. Digital maps are rich in information, intuitive and easy to understand, easy to update, practical and flexible, etc. GIS provides GPS with a visualized original map background, and GPS positioning provides GIS with a new method of collecting data information, and the relationship between the two is getting closer. [0003] However, due to the large amount of water conservancy information data, when the existing navigation system is applied to the field of water conservancy inf...
