Abstract

The invention discloses a positioning method based on geocoding. The positioning method based on the geocoding comprises an encoding module, a geographic information system, a positioning module and other components. According to the positioning method based on the geocoding, by gridding a geographical area, assigning unique codes and mapping the codes with geographical scopes, a user sends code data to a system by various means such as mobile phone text messages, voice, data, the World Wide Web and wireless application protocol (WAP), the system acquires the codes and then translates the codes, queries a backend system and the geographic information system for positioning, and then sends positioning results to the user, and therefore the positioning is completed. By assigning position-related codes for the geographical area, the user queries a location through the codes, and therefore a simple positioning service experience is provided for the user.

200123-123-12345, the information that comprises:

The road name-12345 of 200123 zones-123, PVG correspondence number building, system will translate this and be encoded to No. 888 HuaRong Buildings in Pudong New Area, Shanghai Pudong South Road.

Can inquire corresponding accurate location by this coding.

User's access:

System receives the various data that different user mode accesses is submitted to, and these data are processed, and comprises note, multimedia message, WAP, the Location Request that the modes such as WEB are submitted to.

Geographic Information System:

System forms a new figure layer with data importing to Geographic Information System, code displaying information, the user can revise various data at the enterprising edlin of figure layer, or on Geographic Information System defined range and coding, by chosen area can inquire the coding or based on position, coded query region.

Geographic Information System can be converted to latitude and longitude information with this address information after obtaining the address information of coming from coding translation, realizes the location.
