Department of Land Surveying and Geo-Informatics
Jan 2024 Entry
Established in 1982, the Department of Land Surveying and Geo-Informatics (LSGI) is the only academic unit amongst the local tertiary institutions offering a range of opportunities for education, training and research in the fields of Land Surveying and Geo-Informatics (or Geomatics). The Department has close links with both international and local academic institutions and the professions. By maintaining links with the local professional community through our community service and consultancy activities, our courses and research are oriented towards the needs of Hong Kong.
The Department has identified Urban Informatics and Smart City as its strategic area, with three corresponding focused research directions: a) spatial big data modelling and analytics; b) smart positioning and smart mobility; and c) urban sensing and measurement. As a regional centre of excellence in geomatics research, LSGI is comparable with international reputed academic units in the discipline, as evidenced by both the quantity and quality of the research produced and research grants received.
Laboratory for Smart City and Spatial Data Analytics
The Laboratory aims to bring academics, researchers, professionals and students together to generate innovative ideas, advanced technologies and practical solutions for smart cities. It provides one-stop facilities for research and development, including a spatial big data analytics server, spatial 3D data server, video-conferencing, TV wall, virtual reality (VR) and augmented reality (AR) visualisation systems.
Survey Store and Instrumentation Laboratory
The lab loans equipment and maintains and produces special accessories to support teaching and research activities in the Department.
Digital Cartography Laboratory
This lab is equipped with 40 sets of computers and digitising tablets. Installed with various GIS, CAD and database software, the laboratory is used mostly for teaching and students’ practical work in GIS, cartography and digital mapping.
Underground Utility Survey Laboratory
This lab provides an indoor and controllable environment in which the orientations, depths, sizes, material types and coordinates of various utility networks are carefully designed and recorded. All of these attributes are geo-referenced and integrated into a geographic information system. Surveys are conducted by a range of utility survey and near-surface geophysical equipment.
Geomatics Computing Laboratory
This lab provides a general computing facility for all teaching staff and students in the Department to achieve a number of teaching and learning objectives.
Laboratory for Geographic Information Systems
This lab supports teaching and research on geographic information science and systems; spatial data capture, process, query and analysis; and geo-visualisation.
Photogrammetry and Robotic Vision Laboratory
This lab houses a 30-seat computing space and specialist equipment space. The computing space is equipped with 15 PCs with access to ERDAS Imagine, ContextCapture, Agisoft PhotoScan, PhotoModeler, and Leica Cyclone v6.0 software. The specialist equipment space houses an Intergraph ImageStation DPW, an Intergraph PhotoScan TD, a dual screen Leica LPS DPW, a Peiss P3 analytical stereo plotter, and provides a workspace for laser scanning projects. The lab is also equipped with instruments and sensors for advanced research and development in photogrammetry and robotic vision, and a demonstration platform for planetary mapping and remote sensing research.
Remoted Sensing Laboratory
This lab aims to implement high-impact and high-quality research through cross disciplinary collaborations among faculties/schools and other UGC institutions, provide new insight into a wider range of research areas, and maximize their impact and benefit to society. Apart from continuing to focus on the environmental applications of the state-of-the-art remote sensing systems, as well as the development of techniques to enhance the usefulness of these systems, the lab also expands its research endeavours to the application of remote sensing technologies in teaching and learning.
Cadastre Survey Laboratory
This lab holds various district demarcation sheets, survey sheets and land records from the 1960s up to the present. The Cadastre lab has an A2 scanner and a 3D aerial photo-viewing device.
Hydrographic Survey Laboratory
The hydro lab has evolved into a modern laboratory to meet various university teaching, research and consulting requirements. It has a suite of advanced instruments and software for teaching, research and consulting services.
Jointly set up by the Department and Nanjing University of Aeronautics and Astronautics (NUAA), the laboratory supports four main areas of research: integrated navigation systems; GNSS and positioning; and intelligent transportation systems (ITS) and location based services (LBS).
Laboratory for Deformation and Geohazards Studies
This lab facilitates research in developing new technologies such as GNSS (Global Navigation Satellite Systems), InSAR (Interferometric Synthetic Aperture Radar) and in-situ sensor based technologies, and in studying geohazards such as landslides, earthquakes, land subsidence and structural health. The laboratory is equipped with advanced hardware and software.
