This project aims to study the exportation history of Hong Kong’s quality granite to the Pacific Rim and the construction history of those overseas projects using exported stones in the 19th and 20th century. The following five aspects are investigated:
The colonial government record in 1844 granite was shipped to mainland China. During 1850s and 1860s, granite blocks were exported to mainland China, New South Wales, San Francisco and Siam and used as building materials and paving slabs.
In 1852, the façade of Parrott Building in San Francisco was cladded with quality granite from Hong Kong. Twenty workers and two supervisors from Hong Kong boarded a cross-Pacific ship for the erection of this epoch-making building.
Between 1860 and 1870, granite was quarried in Kowloon, for the construction of the French Catholic Church in Canton. In 1890, the Gap Rock Lighthouse was built by a Hong Kong contractor using the granite from Hong Kong.
Between 1928 and 1933, quality granite was chosen in the projects of The Mausoleum in Nanjing, The Memorial Auditorium and the Memorial Cenotaph in Guangzhou in remembrance of Dr. SUN Yat-sen. These projects were designed by architect LU Yen-chih and constructed partly by contractors from Hong Kong.

Geospatial information science is a discipline that focuses on using geospatial information technology to understand people, places, nature and processes of the earth. IoT refers to Internet of things, the combination of sensors, software and other technologies to connect and exchange data with other devices and systems over the Internet. The era of IoT brings us opportunities and challenges for geospatial information science. In the keynote, five characteristics and three scientific issues of geo-spatial information science in the era of IoT are summarised.

"Essentials of Geographic Information Systems integrates key concepts behind the technology with practical concerns and real-world applications. Recognizing that many potential GIS users are nonspecialists or may only need a few maps, this book is designed to be accessible, pragmatic, and concise. Essentials of Geographic Information Systems also illustrates how GIS is used to ask questions, inform choices, and guide policy. From the melting of the polar ice caps to privacy issues associated with mapping, this book provides a gentle, yet substantive, introduction to the use and application of digital maps, mapping, and GIS."--BCcampus website.

GeoInfo Map is a geospatial information service provided by the Hong Kong Special Administrative Region (HKSAR) Government to the general public, dedicated to facilitate the searching and understanding of geographical locations, the built and natural environments, and public facilities in Hong Kong. In GeoInfo Map, base map details and building information as well as the photo maps are provided by the Lands Department. Departmental and public facilities information is contributed by relevant Government departments while infrastructure and hosting of this website is provided by the Office of Government Chief Information Officer. Geospatial information underpins our daily activities. To cater public’s needs for convenient access to official digital map and geospatial information, LandsD developed this GeoInfo Map service for use by members of the general public. GeoInfo Map served as a common platform to foster sharing of geospatial information by enabling easy public access to the latest facility information released by government departments. Since the launch of the GeoInfo Map in May 2010, the LandsD has been working closely with 29 government departments for the delivery of up-to-date maps and geospatial information service for the public. Over the years, the content of the GeoInfo Map has enriched significantly from provision of 120 types of public facility geospatial information to 270. In order to enhance service quality, the Lands Department has recently conducted a large scale revamping exercise to improve the GeoInfo Map service. To facilitate web surfing with tablet computers and smartphones, responsive web design has been introduced in the revamped website which will detect and adapt to the device in use to deliver a smoother user experience. Apart from enhancing map browsing experience and performance, the new map interface enables users to search for various types of real-time information including weather, traffic, air and beach water quality. GeoInfo Map provides a powerful geographic search engine. It allows users to find any locations in Hong Kong by inputting address information, building names, community and public facility names, place names, road names, lot information, lamp post numbers, and GPS coordinates, etc. Users can also search for public facilities by different categories such as "Sports and Recreation", "Health", etc. GeoInfo Map also provides useful map tools such as drawing tools, share map tools, and drawing tools, etc. Using GeoInfo Map, users can use the navigation tool bar provided to view maps with different scales and level of details, and pan and zoom to any locations in Hong Kong. Apart from the topographic maps, users can have aerial views over the locations of Hong Kong with the Ortho Map function. LandsD is delighted to offer GeoInfo Map to the public. With integrated and comprehensive geospatial information, we hope the GeoInfo Map provides convenience and support to the general public. We would continuously improve the GeoInfo Map service quality. More geospatial information will be incorporated into GeoInfo Map in the future.
