There exist hundreds of thousands of signboard structures in Hong Kong. Numerous signboard erection, alteration and removal works take place every day as business activities prospers. In this connection, we intend to set up a comprehensive electronic data hub for the signboards and signboard activities. The electronic data hub shall be supported by geographic information system (GIS) to operate through 3-dimensional (3D) images. It is also expected to predict potential signboard activities by analysis and sorting of data from internet or other governmental departments, and assist in issuance of statutory and administrative documents.
