Topological Network Model for Improving Urban 3d Data Use

We propose an interface applicable to actual use case for efficiently utilizing costly urban 3D data. We invent Topological Network Model as an interface model for combining numerical urban 3D data and varieties of contents text data. As a result, both types of data can be managed independently and usability of these data enhances. Moreover, we propose a new method of submitting query for urban 3D data based on topological relations. In addition, we propose an effective data transmission method of urban 3D data over the Internet.
