As for the overall objective of this chapter, it was to explain the importance of mapping things, what exactly your mapping is, and preparing\/analyzing your patterns\/data. The chapter starts by explaining the importance. &#8220;Mapping where things are can show you where you need to take action.&#8221; In this instance, they go back to their original question of burglary locations or just overall crimes. They then explain that by mapping out said crimes, they are able to create police routes to monitor the areas with higher crime rates. This tied into &#8220;what to map&#8221; because in this example they wanted to lower crime rates, so they mapped out all the areas with crime, not just some but all crime. They then created a patrol route.<\/p>\n<p>I assumed this is kinda how cops created their routes (not sure if this is even an actual real-life thing or just an example), but it makes sense that this is how they would do it. (Once again, if this is actually how they make their patrols). I also had no clue that GIS could be used for things like this, well not until last week when I officially found out what GIS is.<\/p>\n<p>In the reading, it also talks about categorizing, such as color-coding specified areas so you know what&#8217;s where.

Now, the reason I chose this one specifically is that this is exactly what you see every day on the news; if you watch a weather channel, they&#8217;re going to show the amounts of rainfall, both the most and the least.
