Geographic information acquisition system and method for territorial space planning

The invention relates to the technical field of territorial space planning, and particularly discloses a geographic information acquisition system and method for territorial space planning. The method comprises the following steps: determining a target acquisition area, and dividing a central coverage area and a plurality of peripheral coverage areas; matching the central unmanned aerial vehicle with a plurality of peripheral unmanned aerial vehicles; detection shooting and direct transmission are carried out through the central unmanned aerial vehicle to obtain central geographic information; through the central unmanned aerial vehicle, switching transmission is carried out, and multiple pieces of peripheral geographic information are obtained. A target acquisition area can be divided into a central coverage area and a plurality of peripheral coverage areas, the central coverage area and the plurality of peripheral coverage areas are respectively detected and shot through a central unmanned aerial vehicle an
