AI Technical Summary

Problems solved by technology

The former is time-consuming and labor-intensive, while the latter often has repeated place names, or users forget or enter wrong place names
The method of inputting the latitude and longitude of the earth into the positioning navigator for positioning is simple, but for the general public, the latitude and longitude information of the earth is generally not easy to remember, so it is difficult to popularize
In a word, when the positioning navigator in the prior art is used to locate the geographical position, there are situations of low efficiency and inconvenient use.

Embodiment 1

[0025] The geographic location positioning method of the positioning navigator of the present embodiment comprises the following steps:

[0026] A. Divide the surface digital map of China (in other embodiments, it can be other countries or regions) territory and territorial waters into a network, and make each grid in the network be a square with the same size (in other In an embodiment, the polymorphism may be an equilateral triangle, a rectangle, a regular pentagon or a regular hexagon).

[0027] The corresponding length of the side length of the square grid on the actual surface is 10m (in other embodiments, it can be 5m, 8m or 15m), and calculates the coordinates of each grid on the surface digital map; the coordinates are The vertical and horizontal coordinates set on the surface digital map of China's territory and territorial sea (in other embodiments, the coordinates may be the latitude and longitude of the earth).

[0028] B. Giving each grid a different grid code; t...

Abstract

This invention relates to a kind of position avigraph geographic position locating method. The invention divide fixed region's internal terrene digital map into a sheet of net, and each reseaus size are same. at the same time figure out each reseau coordinates in the terrene digital map; encode each reseau with different reseau code; correlate each reseau reseau code with its coordinates; while through positioning avigraph touch screen import any reseau code, positioning avigraph count this reseau code corresponding coordinates in terrene digital map, then via touch screen to show this reseau geographic position in terrene digital map.

Description

technical field [0001] The invention relates to a geographical position positioning method for positioning a navigator. Background technique [0002] Existing positioning navigators realize positioning and navigation according to GPS signals and digital maps, and for the public, if they want to find a certain place on the digital maps of positioning navigators, they either use the method of constantly flipping through the digital maps, or Using the method of place name search. The former is time-consuming and labor-intensive, while the latter often has repeated place names, or users forget or enter wrong place names. Adopting the method of inputting the longitude and latitude of the earth into the positioning navigator and positioning is simple, but for the general public, the information of the longitude and latitude of the earth is generally not easy to remember, so it is difficult to popularize. In a word, when the positioning navigator in the prior art is used for loca...
