Problems solved by technology

However, if the navigation electronic device obtains its current geographic location and is not in the map database, it cannot present the current geographic location map data information for road navigation services.
This will cause the navigation to display errors on the electronic device, and cannot inform the user of the current accurate location, causing the user to be unable to accurately know their actual geographic location, causing a lot of inconvenience

Abstract

The invention discloses a position display method, which comprises the following steps that: a user provides a navigation destination position on an electronic device, and the electronic device receives satellite signals of a current position and acquires a current geographic position after interpretation and conversion of the signals; the current geographical position is analyzed, compared and calculated according to a geographical database stored in the electronic device, and whether the current geographical position has an existing road in the geographical database is judged; and if the result is negative, the current geographical position and the navigation destination position are further subjected to value analysis and calculation so as to acquire relative linear distance information between the two and direction information to guide the navigation destination position. Besides, the user also can operate the electronic device to adopt the starting position display function for the operation.

Description

technical field [0001] The invention relates to a position display method, in particular to a method for displaying the straight-line distance information and direction information of the current geographical position relative to the navigation destination position. Background technique [0002] With the rapid development of GPS navigation technology, it can accurately provide all-weather, continuous three-dimensional positioning and navigation. However, if the navigation electronic device obtains its current geographic location and is not in the map database, it cannot present the map data information of the current geographic location for road navigation service. This will cause the navigation to display errors on the electronic device, and cannot inform the user of the current accurate location, causing the user to be unable to accurately know its actual geographic location, causing a lot of inconvenience. Contents of the invention [0003] In view of this, the problem...
