Map-based advancing method and electronic map for implementation of map-based advancing method

Abstract

The invention relates to a map-based advancing method and an electronic map for implementation of the map-based advancing method. According to the method, map zooming and translation are performed before distance estimation to make the distance on a map is approximately uniform with length or width of the map, and the length or width marked on a screen can be read directly; map calibration is automatically completed by systems of the electronic map, Beidou and the like, and no matter which direction and position the display screen has, the north, south, west and east directions of the electronic map always accord with real orientations. By the map-based advancing method and the electronic map, the problem that a user is prone to confusing about directions due to difficulty in north determination on site, especially map-based advancing in unfamiliar regions is solved; the prejudice of people sticking to scale sketch maps for years is changed, and high judgment and reading efficiency is achieved; by map zooming and translation with hands, the user can have fun in the sense of mastery; by automatic map calibration, impression and feelings of the user about in-situ landform are deepened.

Description

technical field [0001] The invention relates to a method for traveling according to a map and an electronic map for realizing the method. The method includes selecting a route on the map, estimating distance, and marking a map; the electronic map for realizing the method includes geographic elements, mathematical elements, and auxiliary elements. Background technique [0002] In January 2015, the second edition of "Military Topography and Orienteering" edited by Hu Yunda, published by Wuhan University Press, introduced the method of traveling according to the map, including the following steps: select the route on the map, estimate the distance, and calibrate the map. When estimating the distance, generally use the range meter roller to walk on the map first, and then read the odometer. However, due to the uncertain scale of the electronic map and the smooth and fragile screen, it cannot be implemented in practice. When the map is zoomed, the tiny scale map on the screen zo...

Problems solved by technology

The above steps are cumbersome, time-consuming, and have large errors

[0003] The step of calibrating the map. No matter how the user’s direction changes, the current electronic map will display the map in the fixed direction of the upper north, lower south, left west, and right east of the display screen, which is out of touch with the actual direction. and military operations personnel feel very inconvenient

Users sometimes get lost and can't find the north, especially in unfamiliar areas, it is even more difficult to use the map
