Embodiment Construction

[0051] Refer to attached Figure 1~6 , a processing method for an inverse geocoding processing system, comprising the following steps,

[0052] 1) Obtain geographical location information data from a map in MapInfo format

[0053] The geographic location information data includes the longitude and latitude data of each province in China, the name and number of each province, the latitude and longitude data of each city, the name and number of each city, the latitude and longitude data of each county, the name and number of each county, and the features and roads of each county. Longitude and latitude data, feature names, road names and grades and other related information;

[0054] 2) Process and store the geographic location information obtained in step 1), and the processing and storage structure is as follows,

[0055] The latitude and longitude data of provincial borders are stored in txt file format, and the data are separated by ",". The latitude and longitude data are...

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...
