“Since young, I always believe in seeing things in a different perspective is more exciting and enlightening than what conventional ways can offer. Seeing or tackling a problem in a different perspective is the easiest way to generated and accumulated knowledge. Doing research is no different; it is about solving problems with an aim to improve current technology to better serve mankind. The field of Geospatial is as exciting as ever in changing mankind’s perspective of the their surroundings. From conventional ground work to state-of-the-art satellite technology, INSTeG have the expertise in a wide variety of R&D activities and mapping methodology. The details of the ground work put together with the perspective from the space-borne sensor forms an important outlook to the public ranging from everyday end user to decision maker all around the world. With a conducive and resourceful environment under one roof, one can easily excel in their work. Young scientist and researcher who share the same dreams of making a different in their communities are highly recommended to take this opportunity to thrive.”

Research Projects	:	..	Air quality is an issue that concerns the general public the most as it can cause a country’s economy to stagnant besides its well
		..	known threat to the environment and human health. In many developed and developing nation, air pollution has caused an estimated side effect of approximately two million premature deaths worldwide per year. In a country of maritime climate such as Malaysia, severe cases of air pollution are generally affected by our neighboring country as a result of forest fire and monsoon wind. This event usually occurred during Southwest Monsoon season (between May and September), which brings haze from Sumatra region to the western side of Peninsular Malaysia. Other local sources of air pollutions include vehicle emission, power generation, industrial emission, open burning and forest fires. The health damage in Malaysia resulted from air pollution had a record of approximate US$43 million and others related productivity losses approximate US$1.5 million in year 1997. In 2006, air pollution has caused Singapore US$50 million of estimated economic loss at since the start of the haze. In order to make use of the NASA satellite sensor for air quality monitoring in this region, a thorough study of the uncertainty is required. This is because countries situated under maritime climate are more dynamic in its atmospheric turbulence compare to continental region due to the influence of seasonal monsoon wind.
