LSGI Delegation to Wuhan Remote Sensing Week

From 13 to 17 October 2018, a delegation of staff and students from the Department of Land Surveying and Geo-Informatics (LSGI) participated in the Remote Sensing Week at Wuhan University which ranks the top in the world in the discipline of Remote Sensing according to Shanghai Ranking. Two major conferences on “National Geographical Conditions Monitoring and Applications” and “Advanced Remote Sensing” were being held. Two keynote speeches were delivered by Prof. John Shi, Head of LSGI, and Prof. Meipo Kwan, Distinguished Chair Professor of LSGI. LSGI academics gave four presentations and the latest research development in Remote Sensing were shared. About 200 people were in attendance. Academic visits were also conducted to i) School of Remote Sensing and Information Engineering and ii) the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing were conducted. In which, research areas of LSGI were introduced and discussions on potential research collaborations between two universities were covered. In addition to exchanges between LSGI students and their mainland counterparts, there were tours of the Wuhan university campus and some historic buildings in the city. It was a rewarding trip for all concerned. Below are some of students’ reflections from the trip: Yip Cho Yui, Year 3 “The remote sensing week has covered a wide angle of topics, such as remote sensing on human behavioural science, resource management and spatial big data, which is so aspiring to see how remote sensing is shaping our future for monitoring social issues and reaction to natural hazards, it is all about improving the life quality and safety of our citizens. It would be so excited to participate my future career to this ever-changing field. Moreover, remote sensing research is so up-to-date and new breaks through are coming up as technology and researches evolved. I cannot believe how quick pace and fast-growing this industry is evolving towards. Rarely could we have a chance to attend such a high quality conference, I feel that students or ordinary people would still benefits.”   Yeung Ling Yuk, Year 3 “I cannot wait to attend to those conferences and acquired those astonishing speeches from those international wellknown professors and scholars. Although some of the topics are quite advanced and beyond my understanding on remote sensing, I still reckoned this trip is worthy to attempt. Additionally, Wuhan is a city with antique beauty because of its plentiful and splendid historic backgrounds. The combination of ancient and modern buildings made Wuhan becomes one of the best-view cities in China.” Wong Tin Wai Phoebe, PhD student “The study trip was great that we all had an enjoyable time in Wuhan. The talks delivered by the professors were inspiring and I have more new ideas for my coming research. I look forward to more opportunities to visit other universities.”

Kick-off Forum of the Development of Test/Survey Methods and Specifications for Underground Utility Survey

Underground pipe burst? Pipe leak? How often are these problems heard in the spiderweb underground in Hong Kong? In first half 2018, there are 13 cases reported in public media, those not appeared in public media are estimated to be at least 30 times more. Funded by ITF General Support Scheme and Sum Kee Construction Ltd, as well as support by 4 Government departments and MTR, Ir Dr. Wallace Lai from Department of Land Surveying and Geo-Informatics (LSGI) hosted a public kick-off forum on 31 August 2018, announcing the start of a two-year project for establishing a set of utility survey specification for accreditation. The $1.37M project is entitled ‘Development of Specifications and Standards for Underground Utility (UU) Survey based on Nondestructive Testing, Surveying, Imaging and Diagnostic (NDTSID) Approaches’. The forum attracted 78 participants from 29 units including Government, utility stakeholders, service providers, and commercial lab. The project represents an effort of knowledge transfer from basic/applied research to practical use in Hong Kong and elsewhere. LSGI will take the lead in this project and will conduct rounds of consultation, reaching consensus of the specifications for procurement by the Government and various utility stakeholders. By the end of the project, six NDTSID approaches will become accreditable by Hong Kong Accreditation Services under the Hong Kong Laboratory Accreditation Scheme (HOKLAS) of the Government, the first attempt and showcase to the world. It is believed that the deliverables will benchmark the expected and practically viable standards of the NDTSID technologies in underground utility sector.
