Problems solved by technology

However, in uninhabited areas where there is no network information, or when conditions do not permit, navigation becomes very difficult
In this case, whether walking on foot or driving, it is possible to get lost, especially in the process of long-distance driving, it is almost impossible not to go the wrong way, and in serious cases, it will endanger life and property safety.
[0003] In addition, for field geological work, such as geological mapping, routes need to be designed in advance, and the designed routes are generally only displayed on the topographic map, and there is no designed route in the handheld GPS device, so geologists need to go through the terrain in the field. Try to confirm whether you are near the design route, however, this confirmation process is not only inefficient, but also has a large error

Embodiment 1

[0036] According to the data, rare earth ore prospecting clues were found in an uninhabited area in Ejina Banner, Alxa, Inner Mongolia, and field surveys were required. The location only had one latitude and longitude coordinates, and it was necessary to reach the destination by itself.

[0037] (1) if figure 2 As shown, according to the given latitude and longitude coordinates, mark the destination and station location on Google Earth. Generally, dirt roads or ruts can be seen in places where vehicles can pass, but where there are no roads or ruts, even if they are flat, they will It is impossible to confirm that the vehicle can pass and may cause danger;

[0038] (2) if image 3 As shown, starting from the station, carefully check the satellite image, continuously draw the path that the vehicle can pass to the destination, and save the drawn path as a kml format file;

[0039] (3) if Figure 4 As shown, open the saved kml format file with notepad, you can see ...

Embodiment 2

[0046] According to the task requirements, a large-scale field mapping work is required for a rare earth prospecting prospecting area in the central Daxinganling Mountains, Inner Mongolia.

[0047] (1) if Figure 7 As shown, after viewing satellite images and field surveys, the area is covered by forests, with extremely poor visibility and easy to get lost, and there is no network signal in this area, and it is very dangerous to be unable to contact the outside world after getting lost;

[0048] (2) if Figure 8 As shown, through satellite images and regional data, the mapping route is designed on Google earth. The principle of designing the route is to design the route on the ridge as much as possible. First, it is easier to climb the mountain; The drawing efficiency is high and the accuracy is high. Third, when the work is completed, the drawing working group can return to the road through the designed route;

[0049] (3) the route designed on Google earth is con...

Abstract

The invention provides a method for making a GPS track by using a satellite image. The method comprises the steps of 1, acquiring path information by using a path drawing module, drawing a path with useful information on the satellite image, and saving the path in a format of a file with readable inflection point coordinates; 2, converting inflection point coordinates in the file capable of reading inflection point coordinates into a format capable of being recognized by handheld GPS equipment through a code conversion module. When the GPS track is made by means of the method, an offline navigation or route design function is achieved by inputting a route designed on the satellite image into the handheld GPS equipment; no third-party software is needed except satellite image software, Mapsource software and notepad software; people do not need to worry about that the track cannot be displayed since there is no network in the wild; the step of pathfinding is omitted, and the method is quick, efficient and safe.

Description

technical field [0001] The invention relates to a method for generating a GPS track, in particular to an operation method for generating a GPS track by using satellite images. Background technique [0002] When working in an unfamiliar field environment, in order to ensure the safety and efficient work of the staff's life and property, navigation is an essential link. The current navigation is generally through mobile phone map software navigation or asking local people to guide the way, or designing navigation routes based on topographic maps. However, in uninhabited areas where there is no network information, or when conditions do not permit, navigation becomes very difficult. In this case, whether walking on foot or driving, it is possible to get lost, especially in the process of long-distance driving, it is almost impossible not to go the wrong way, and in serious cases, it will endanger the safety of life and property. [0003] In addition, for field geological work...
