GEOB270 enabled me to gain a solid first experience with ArcGIS. It taught me how to organise, parse, filter and mine different data in order to focus my analysis on the key elements which I want to portray in a final map. Most importantly, the labs of this thorough introduction class to Geographic Information Science allowed me to understand the important basic analysis tool of ArcToolBox which enabled me to carry a thorough analysis of the different layers in my final project to ultimately construct 4 different maps, each with a different and focussed message but which could be easily compared to each other.
