Augmented Reality (AR) is the technology that provides users with real-time helpful information on the real scenes as the users' requirement. The AR system supplies helpful information for user by using user interfaces and systematical combination between real scenes and related information. In this paper, we present our bird's-eye view system to look virtual buildings with the harmony of environment in civil architecture. We can intuitively look the harmony among virtual buildings and current environment and navigate in the environment with this system. The system consists of two parts. One is the construction part of aid information and the other is the navigation part of pilot environment. The first part systematically combines contour data, 3D modeling data for buildings, road and river data and text information, and so forth. The other part provides users with aid information on the real scenes by user interface while they navigate in the real scenes. As mentioned above, we can easily and quickly get helpful information on the real scenes. The system can be widely used in various applications, such as urban planning, construction planning, virtual studio, movie, military, education, and so on.
