SG Remote Sensing Workshop 2021

Tackling climate change and environment issues using satellite data at a remote sensing workshop.  

50 secondary school, junior college and polytechnic students took part in the inaugural SG Remote Sensing Workshop recently, organised by Office for Space Technology and Industry, Singapore (OSTIn),  the Centre for Remote Imaging, Sensing and Processing (CRISP) and ST Engineering Geo-Insights.

Over the course of 2 weeks (22 Nov to 03 Dec 2021) culminating in a showcase of their research efforts on the 3rd Dec 2021, the students worked together in small groups to use satellite data to study the impact of flooding, forest fires, coastal changes, and urban heat island effects, under the mentorship of researchers from CRISP and Geo-Insights. They learnt how to access satellite data and use tools and software such as Google Earth engine, Sentinel Explorer and ArcGIS. The students also had the opportunity to go on a virtual visit of CRISP to witness how data is sent to and received from satellites. 

SST is represented by the following students in this workshop:
Ong Zhi Xuan (S3-01), Osaid Muhammad (S3-07), Akila Rajesh, Giscelle Damara, Felicia Evelyn Handojo (S3-08)

Ong Zhi Xuan (S3-01) also received the Most Innovative Project as part of a 5-member joint-school team. 

Their project was on using remote sensing data to study the Urban Heat Island effect.
