Air-ground integrated accurate range marking method based on GIS (Geographic Information System)

The invention discloses an air-ground integrated accurate range marking method based on GIS (Geographic Information System), which comprises the following steps that: 1, when a case occurs, a command center receives information and sends the case to a flying finger of an unmanned aerial vehicle; 2, the unmanned aerial vehicle drives the vehicle to reach the position near the site, the unmanned aerial vehicle takes off, the unmanned aerial vehicle flies around the site where the emergency event occurs, a flight path is drawn, namely a rough range, and at the moment, part of emergency solutions can be designed; 3, the unmanned aerial vehicle pilot continues to control the unmanned aerial vehicle to fly for a second circle, laser ranging is started, and during flying, laser is aligned with the case occurrence range; and 4, atmosphere monitoring micro stations are uniformly deployed in the monitoring range, wherein atmosphere monitoring photosensitive devices and 4G communication modules are arranged in the atmos
