A bird's eye view is a three-dimensional view drawn from a height overlooking the ups and downs of the ground according to the perspective principle. Simply put, the image you see when you look down at an area from the air is more realistic than the plan. A bird's-eye view can express the geographical landscape and other contents by various three-dimensional means, and can be drawn by selecting the most ideal overlooking angle and appropriate proportion according to the needs.

Bird's-eye view is also an important space design "language" that cannot be ignored. The designer's spatial intuition can be more integrated into the design. Only by using perspective principle to accurately grasp the objects in space can designers' intuition and feelings be mobilized to the maximum extent. Whether it is the change of the times or the development of technology, it plays an irreplaceable role in the process of planning and design creation.
