Raster data is how we get a colorful visualization of our world through GIS mapping. There are various benefits and cons to raster data. However, in many circumstances, the pros outweigh the cons. Raster data gives us a visual interpretation of things such as elevation, vegetation and different types of dimensions of buildings. Raster analysis could definitely be used in other courses I have taken here at Salt Lake Community College. As I pursue a degree in the Earth sciences, many assignments and studies I have participated in have used Raster data. One example that comes immediately to mind is my Natural Disasters class which I have taken. We used Raster data to observe different areas that pose a natural threat to communities. When discussing and analyzing these communities, we have been able to use Raster data to see different coloring in the earth, which indicates changes in elevation, vegetation and soil types. Obtaining these visuals allows us to see where the earth might change, locations where natural disasters have already occurred and the damage that has been caused. Another class in which I used raster data was Physical Geography. Raster data allowed me in this class to see different earthquake fault lines and various types of Earth structures. Although we could have used Vector data for some of these things, it would not have been as informative as Raster data. Furthermore, I enjoy using Raster data in my own personal life as I observe different locations from an aerial perspective. Now that I have a better understanding of some of the benefits of Raster data, I am anxious to see how I can apply it to other classes that I will be taking in the future.
