LiDAR surveying is being increasingly used worldwide for its accurate, cost effective, and fast acquisition of topographical and imagery data. It provides high resolution 3D data of large swaths of landscape at rates of dozens of square kilometers per hour, which can then be used create numerous products that are useful for many engineering, environmental, natural resource, and infrastructure applications.  The technology has been in use in Malaysia since 1989, and its users have benefited from its many cost, accuracy, and speed advantages; one such user are flood management specialists.

Given that flooding is a common issue that Malaysia as a tropical country with two monsoon seasons frequently faces, management of flooding and flood waters is a constant requirement in order to prevent disasters and mitigate economic loss. Numerous places such as the Klang Valley and the Damansara River are prone to flash flooding during rainfall seasons, and understanding the landscape is crucial in fields such as determining where to build infrastructure, redirecting flood water, planning new construction and expansion of settlements, and so on. Climate change in the future is liable to increase the risks further, and will make said management even more important. To assist in this, airborne LiDAR data can be utilized to build Digital Surface Models that indicate what the ground surface looks like, which can then be used to analyze drainage flow patterns and perform volume calculations.  

Despite its power, poor understanding of LiDAR and its data can lead to inferior analyses and utilization, and oftentimes the full potential of the data is unrealized. There are numerous nuances in the management and utilization of LiDAR data that changes depending on the quality and resolution of the data, as well as the specific applications that it’s being used for. This course will teach attendees the principles of LiDAR and how to effectively use it, and will include a hands-on practical exercise using popular freeware for LiDAR data. (Participants must bring their own laptop for these purposes).


Engineers and related staff who are working in the following fields:
• Dam
• Water Supply and Flood Management
• Telecommunications & Other Urban Planning     
• Road
• Mining
• Forest/Habitat Assessment
• Slope Stability    
• Pipeline
• Railway
• Transmission Line    


At the end of this course you should:
• Gain a basic understanding of LiDAR  and LiDAR data
• Know all the potential applications of LiDAR
• Understand how to use LiDAR data
• Know how to analyze the quality of LiDAR data
• Understand how to create a TOR for LiDAR survey which will meet a project's requirements


Ms. Trudy R. Ganendra graduated from the University of Cambridge in 1997 with a Masters of Engineering degree, and in 1999, obtained a Master’s of Science in Environmental Engineering from Imperial College London. In 2001, she was appointed as the Director of Ground Data Solutions R&D Sdn. Bhd. (GDS), a Malaysian-owned LiDAR survey and mapping service provider. GDS has been providing accurate, cost-efficient mapping and mapping products to a broad range of clients since 1991, including developers, planners, and designers throughout Southeast Asia. GDS is the only local service provider of airborne LiDAR and digital imagery surveys in Malaysia: it owns its own LiDAR systems, is involved in research and development of said technology, and is a direct operator with a proven track record of more than 20 years in the industry in Malaysia and Southeast Asia. She is responsible for the day-to-day activities of GDS in both business and operational capacities. Her business responsibilities encompass corporate policies, financial analysis and strategic relations. The operational aspects involve bidding, planning and execution as well as reporting and client liaison. To date, she has successfully executed 71 LiDAR projects.

Dr. GS Ebrahim Taherzadeh Mobarakeh was born in Isfahan, Iran in 1982. He received his Bachelor of Natural Resource Engineering from Maybod University in 2004, Masters of Remote Sensing & GIS from Universiti Putra Malaysia in 2009 and Ph.D in Spatial Information Engineering from University Putra Malaysia in 2014. His thesis was on the development of generic models to extract roof materials using high spatial resolution satellite imagery. Currently, he is working as a Remote Sensing Specialist at Ground Data Solutions R&D Sdn. Bhd., a Malaysian LiDAR survey and mapping service provider. His major research effort includes urban remote sensing using high resolution imagery, hyperspectral, and LiDAR data, and has published 12 technical papers on these subjects in international conferences and journals.
