Description

Method for creating a drone map [

The present invention relates to a method for generating a dron map for disaster preparedness.

In Korea, the mountainous terrain occupies 70% of the land area. Due to the nature of forest fires, the forest fires are not only large but also very difficult to suppress due to natural variables such as wind changes. It is one. These forest fires are carried on the wind and destroy the forests, so if damage is not suppressed early, the damage is very serious.

Since firefighting vehicles can not enter the fire area due to the nature of the mountainous terrain, firefighters have had to inconveniently fire the heavy firefighting equipment to the fire site to suppress the fire, Firefighters who crashed in the lower part of the ridge had the problem of falling down as if surrounded by flames and causing serious injuries to firefighters who were fighting the fire. In addition, there is a case that the ignition point or the proceeding direction of the forest fire can not be grasped correctly, so that it is difficult to judge the evacuation direction wrongly or to judge the evolution direction wrongly.

In order to solve this problem, although the location of the fire and the direction of the forest fire are checked by using the dron which is not restricted by the altitude, in reality, the location where the vehicle or fire truck can approach the dron It is a reality that utilization is not high because there are many cases which are extremely limited.
