Processing method of reverse geocoding processing system

Abstract

The invention provides a processing method of a reverse geocoding processing system, and relates to a processing system converting geographical coordinates into corresponding address descriptions and a processing method of the processing system. The processing method comprises the steps of 1) obtaining geographical location information data; 2) conducting processing and storage; 3) loading the data stored in the step 2); 4) searching a cache system of the step 3) for names corresponding to the coordinates, 4.1) searching for province name information, 4.2) searching for city name information, 4.3) searching for district / county name information, 4.4) searching for nearest ground feature information, and 4.5) searching for nearest road information; 5) combining search results into a complete address description and returning the address description to a requester.

Description

technical field [0001] The invention relates to a processing method of an inverse geocoding processing system, which relates to a processing system and a processing method for converting geographic coordinates into corresponding address representations. Background technique [0002] In recent years, the automobile industry has become a pillar industry in our country, and the role of automobiles in daily life production has become more and more prominent. However, for those managers who use GIS+GPS technology to manage their large fleets, how can they quickly and efficiently know the precise geographic location of their vehicles at a certain moment, so as to determine whether the vehicle is driving as required. This service of obtaining the geographic location of the vehicle can be called reverse geocoding. [0003] Reverse Geocoding (Reverse Geocoding) can also be called reverse address query, which refers to the process of obtaining the corresponding geographic location fr...

Problems solved by technology

[0004] It is precisely because of the above needs that more and more map service providers at home and abroad (such as Google Maps, Yahoo Maps, Map ABC, Map Bar, Microsoft Maps) have successively carried out research in this area and provided corresponding APIs for Call, but some of these APIs do not support the development of Chinese maps (such as Yahoo Maps, Microsoft Maps), and some have a maximum number of queries per day (such as Google Maps, Microsoft Maps), and can only query road-related information in provinces and cities. However, other relevant information such as administrative codes and road grades cannot be queried. Therefore, there are great restrictions and inconveniences for domestic users.
