The 2006/7 saw several developments of the Department. All the academic programs ran smoothly and healthy. The MSc in Geomatics changed from part-time mode to mixed mode, which allows the recruitment of both part-time and full time students. With this change 13 Chinese Mainland students joined the program. Education philosophy of all round development of students was further promoted. We sent one student to Greece for summer placement under IAESTE program; 1 student to the University of New Brunswick and 2 to the Curtin University of Technology under student exchange program; and organized a study tour to Xian with participation of 28 students. Our students actively participated in community service under the instruction of Mr. LAM, Joseph. Two course-based projects were chosen by the university for Community Service Leaning Awards 2006/7. LSGI produced 20 MSc/PgD graduates, 35 BSc. graduates, including PT program and 51 HD graduates. Research activities remain strong. 15 new projects with total funding support of $5.2m were awarded in the year, of which 5 are CERG projects and 3 CERG fundable projects. Our staff published 64 refereed journal papers and 8 books/book chapters. 2 PhD and 1 MPhil graduated. The achievements of our staff members have been well recognized. Prof. MOK, Esmond got the President’s Award for Excellent Performance Achievement with category team award – service; Prof. SHI, John received several awards in the year: Chang Jiang Scholar (Chair Professorship) issued jointly by Ministry of Education (MoE), China and Li Ka Shing Foundation Hong Kong; Distinguished Young Scholar Fund (B) from National Natural Science Foundation, China; and the first class Progress Award in Science and Technology by MoE.

Current Research Projects and Summary Description (Cont’d) New Research Projects funded in the reporting year:- CHEN, Wu Investigators: CHEN, Wu, CHEN, Yong-qi and DING, Xiao-li Title: Seamless Ionosphere Modeling for GNSS Augmentation (G-U304) Amt of funds: $150,000 Status: Start date : 01-Jan-2007 Description: Ionospheric delay error is one of the major error sources in GNSS (i.e. GPS,

Galileo, and GLONASS) positioning. In recent years, different GNSS augmentation systems (WAAS, EGNOS, and other regional systems) have been developed to improve GNSS positioning accuracy and integrity. The ionospheric models adopted by these augmentation systems are grid models with the grid spacing of 5 to 10 degrees. However, due to complexity of ionospheric TEC distribution in high or low latitude regions, the accuracy of current ionospheric models is comparably lower in these regions. This proposed research project tries to develop seamless ionospheric models that can be applied in any part of the world to improve GNSS positioning accuracy and integrity. This research will concentrates on three areas. Firstly, an accurate and unified ionospheric TEC model that can be applied in any part of the world will be developed. Secondly, based on long-term GPS observation data, the project tries to develop the statistical models for ionospheric residual errors for integrity bounds determination. The third area is trying to study long-term ionospheric TEC distributions and changes in low latitude regions.

CHEN, Yong-qi Investigators: CHEN, Yong-qi, IZ, H.B., XU, Pei-Liang and WU, Ji-cang Title: Development of the methodologies for efficient extraction of spatiotemporal

distribution of crust deformations at regional scale from geodetic data (B-Q02B) Amt of funds: $378,690 Status: Start date : 1-Jan-2007 Description: The December 2004 Indonesian tsunami sent a clear and loud message to all over

the world that we must efficiently monitor our living planet to mitigate losses caused by natural disasters. Geodetic measurements, particularly nowadays’ multi-epoch GPS surveys and continuous GPS networks, have been widely used for monitoring crust deformations with an aim to identify potential geological hazards. This proposal is to develop the methodologies for efficient extraction of spatiotemporal distribution of crust deformations from geodetic measurements at a regional scale. Three major issues will be addressed: (1) approach for determining the detailed information on crust deformations in space and time domains; (2) method for identifying the area of stress/strain accumulation; and (3) optimal design of monitoring schemes. The developments arising from addressing the above issues can efficiently gauge spatiotemporal distribution of crust deformations and help identify potential geological hazards. The developed methodologies will be used to analyze the data of 6 GPS campaigns in North China for identifying potential intra-plate earthquakes and the GPS measurements at 17 continuous GPS stations in Hong Kong region for assessing its geological stability.

(B-Q02C) Amt of funds: $476,000 Status: Start date : 15-Dec-2006 Description: This project aims to extend the so-called corner reflector InSAR (CR-InSAR)

technology and to integrate it with GPS to develop an advanced technology for ground deformation monitoring. The technology will make use of the advantages of both CR-InSAR and GPS, and be able to monitor routinely a significant number of ground points on almost any types of terrain surface over a long time period (e.g., years or longer).

Multiple Mission Satellite Altimetry (B-Q02D) Amt of funds: $386,000 Status: Start date : 01-Oct-2006 Description: Ocean tides play a significant role in climate due to its complex interactions

between ocean and atmosphere. Tides have strong effects also on circulations near coastal regions and on continental shelves. Most of the great ports of the world including Hong Kong are affected by tides and several socio-economic benefits



are possible by exploiting the coastal tidal regime such as pollution associated with large industrial developments and centers of population which is diluted and discharged to sea where there are large regular exchanges of tidal water. Engineering designs such as sewage outfall pipes depends on the water depth and currents at the sea-wall end, and strong tidal flows. Although currently semidiurnal and diurnal barotropic ocean tides are known in deep oceans for depth>1000 m to within 2 cm rms and with a spatial resolution of 50 km thanks to the TOPEX/POSEIDON satellite altimetry and advances in numerical modeling methodologies, tides are significantly less well known in the coastal regions, over continental shelves, and in polar oceans due to limited observations with adequate spatial resolutions as well as complicated spectra due to non-linear hydrodynamics. In this study we propose to improve the coastal barotropic tidal models in the South China Sea with a focus on Hong Kong and its surrounding seas using multiple mission historic and operating satellite altimeter data, including Geosat, ERS-1, ERS-2, T/P, GFO, ENVISAT, JASON-1 and European Space Agency’s Cryosat carrying the synthetic aperture interferometric radar altimeter (SIRAL). We will also study the role of internal tides in predicting of tidal currents in the Hong Kong harbor and surrounding seas.

JIANG, Bin Investigators: JIANG, Bin Title: Development of Topological Analysis Methods and Their Applications in Hong

Kong Transport Modelling (G-YE85) Amt of funds: $129,612 Status: Start date : 30-Sep-2006 Description: The general aim of this project, as indicated by the proposal title, is to further

develop topological analysis methods for uncovering geographic knowledge for better decision making with Geographic Information Systems (GIS). Although topology is a fundamental concept in building up GIS software, topological analysis we refer to here has much wide and deep implications to GIS (Jiang 2005). First, it is intended for spatial analysis and for uncovering geospatial knowledge, rather than topological data structure implemented in current GIS software. Second, the meaning of topology with topological analysis is not constrained by geometric primitives such as points, lines, and areas, but could refer to geographic objects. For example, a line segment is just a geometric primitive, while a named street is geographic object. A topology can be setup based on the notion of named streets to examine how each named street is interconnected to each other. This particular topology, or so called topological analysis, provides a better understanding of transport systems (Jiang and Claramunt 2004). For example, how well a (named) street is connected to its immediate streets? And how well a street is integrated to all other streets? Answers to the questions have a deep implication to predicting traffic flows and pedestrian movement in urban environments (Hillier et al. 1993). The topological analysis, we believe, represents a significant paradigm shift in terms of spatial analysis, as most, if not all, of existing spatial analysis methods are based on a geometric paradigm. The shift from geometry to topology in terms of spatial analysis is triggered by a recent ad
