Abstract

The invention relates to a geographical-position related hash virtual geocoding method and a system. The geographical-position related hash virtual geocoding method comprises the following steps of: diving the earth surface space repeatedly by adopting a region quadtree method based on the uniform division of a spherical surface; establishing indexes based on the hash plaintext coding for a terrain block and a scene block; indexing the user incarnation by adopting the hash plaintext virtual geocoding in the virtual world; and storing the indexes based on the hash plaintext coding of all data into a data index database based on the hash plaintext coding according to the division layer. According to the method, a set of space dividing and indexing mechanism is established and abstracted into a mathematical model, the space dividing and indexing mechanism can be expanded to be used for the real world division and the three-dimensional earth division, and the space dividing and indexing mechanism can be used as a core index data structure in a system to map various objects in the virtual world. Due to the hash plaintext virtual geocoding, the user incarnation and various element models in the three-dimensional earth scene can be indexed, and the relative positions of objects in the virtual world and the real world can be unified.

Description

technical field [0001] The invention relates to the field of geographic information systems, in particular to a hash virtual geographic coding method and system related to geographic location. Background technique [0002] Geocoding, also known as address matching, refers to the process of mapping addresses into geographic coordinates, providing a way to convert geographic location information described as text addresses into geographic coordinates. Virtual geocoding is a coordinate code that indexes addresses mapped with the real world in the virtual world, and is the product of geographic information systems expressed in three dimensions. Geographic information science is a science developed on the basis of geography, cartography, surveying and computer science. The software entity based on it is called geographic information system (GIS). Virtual reality (VR) technology is a mapping of the real world, using computer simulation to generate a three-dimensional virtual spac...
