We construct a three dimensional map database which consists of road signs, curve mirrors, electric poles, traffic signals, fences, guard rails, trees, walls, buildings and so on of street space in Tomari Area in Maebaru City in Fukuoka Prefecture. We examined the system requirements about three dimensional real world database systems when we built the three dimensional map database based on the surface model where the shape of features is represented by a set of triangular polygons. We concluded that some techniques are needed to manage the database. They are representative value representation such as length and width of features, spatial constraint to describe that different features have the same shape, spatial constraint to describe that different triangular polygons exist on the same plane, management of parent-child relationships between three dimensional objects, representation of the direction of surfaces of features, management of texture coordinate systems. |
