When reading the handout on geographic information system, I found that the section discussing the use of GIS during urban planning to be very interesting. GIS is an essential tool in sustainable development. This is especially true in urban areas where there is a steady increase in population. I think the practicality of GIS technology is vast and will continue to evolve as other forms of technology change. I like that there is a lot of positivity that comes from using GIS during urban planning. It allows developers to use empirical data to determine a healthy, optimum area to create cities. Because of this, the people who will move into these cities will have the opportunity to experience a higher quality of life as opposed to cities built on any type of land.
