Abstract

The invention relates to the technical field of data processing, in particular to a global geographic grid system based on a differential geometry principle, which comprises a core model module, a data management module, a progressive transmission module and a visualization module, the core model module is used for realizing an SQT subdivision model and a UEC coding model of a regular icosahedral triangle grid, realizing an adjacent relation search algorithm and a grid hierarchical relation search algorithm between grids through the UEC coding model, and constructing a global geography gridding object model based on the search algorithm; the data management module is used for providing a related management function of data of the global geography gridding object model, and realizing integration of GIS traditional vector data on the gridding object model through a quick conversion algorithm of geographic coordinates and grid codes and vector data gridding for keeping a topological relation; and storing the gridding object model data into a document type database for management. The problem that a global geographic grid model is easy to respond slowly is solved.

Description

Technical field [0001] The present invention relates to the field of data processing, and Background technique [0002] Global geographic network system is directly crosscoming the surface of the Earth, avoiding various types of variations generated by the map projection, performing a unified specification expression, managing and analyzing the fusion of multi-diversity data for geospatial data of any range of geospatial data around the world. However, expressing and managing relatively independent geographic entity object data has always been difficult in the field of geographical grid system research. Currently, spatial data organization management in the GIS field typically describes geographic entities or phenomena in the real world with some spatial data model, from macro believes that geographic space is composed of spatial data model. Among them, the object concept model of abstract expression geographic entities is different from the space geometric information descriptio...
