Abstract

The invention discloses a Chinese geographic coding and decoding method. The method comprises the following steps: a GIS (Geographic Information System) including an electronic map, coordinate data and geological information data is called for use, wherein each map unit on the electronic map corresponds to one coordinate data and a group of geographic information data; as for each map unit, a standard Chinese geographic indication is set and stored in a standard data base, the storage position of the standard Chinese geographic indication in the standard data base is mapped in the geographic information data, and the standard Chinese geographic indication comprises separator fields, pointing fields and identification fields; and as for each standard Chinese geographic indication, a fuzzy Chinese geographic indication is set and stored in a fuzzy data base, the storage position of the fuzzy Chinese geographic indication in the fuzzy data base is mapped in the geographic information data, the mapping of the fuzzy Chinese geographic indication and that of the standard Chinese geographic indication are correlated, and the fuzzy Chinese geographic indication comprises a primary fuzzy Chinese geographic indication and a secondary fuzzy Chinese geographic indication.

Description

technical field

[0001] The invention relates to a geographical information system, in particular to a Chinese geographical encoding and decoding method and device applied to the geographical information system. Background technique

[0002] At present, the public security industry has established a large number of databases such as resident population database, key population database, criminal investigation database, 110 police information database, etc. and corresponding business application systems. The construction of the police integrated geographic information system must be effectively combined with these data to realize the visual analysis of business information based on geographic information. Only when visualization and integrated geographic information applications are realized can the system have vitality and play its due role.

[0003] It has been found in practice that although the current electronic map and geographic information system GIS have realized the...
