Through GEOB 270, I have learnt a lot about GIS. When I first heard about GIS, I brushed it off, thinking that it was irrelevant to me, even though I was a Geography major. My next encounter with GIS taught me how useful GIS was – my friends actually collected their own data in Thailand and developed their thesis based on this data and represented it visibly on a map using GIS. This sparked my interest and I wanted to learn more. GEOB 270 allowed me to fully understand the basics of this amazing technology. I am able to perform basic GIS analysis such as sourcing spatial datasets online, to parse and filter them, to fix misaligned and improperly referenced data, and to make effect maps to display my research findings.
