Chapter 1:
Chapter 1 is primarily focused on the introduction of the basic concepts of Web GIS and how it is different from other traditional GIS systems. In this chapter, the reader is made aware of the fact that Web GIS is not only about making maps but is more about connecting data, tools, and people through the internet. One of the major ideas presented in this chapter is that the field of GIS has moved from being static and desktop-based to being interactive and web-based, like ArcGIS Online. Another significant idea presented in the chapter is that of web GIS as a system of content, capability, and users, which is vital in the sense that it indicates the fact that GIS is not only about the application but is a complete environment in itself. In the chapter, the reader is made aware of the fact that maps are no longer only about the visualization of the data but also about the interface of the data. In the context of maps and visualization of the same, the concept of layers is presented in the chapter, where the reader is made aware of the fact that different kinds of information can be stacked and turned on and off as per the requirement of the person using the map. Another significant idea presented in the chapter is that the data can be obtained from anywhere and can be shared with anyone.
The tutorial part of this chapter assisted in this learning because we were able to learn and understand how to use ArcGIS Online. By creating maps and viewing maps, I learned that it is quite easy to combine information and display it in a meaningful way. I also learned that symbols can influence how information is interpreted. One of my thoughts while learning this chapter is how much control the user has over information being displayed. This chapter has helped me learn that Web GIS is not only about mapping. It is about communication and collaboration.
Chapter 2:
Chapter 2 is a continuation of the concepts learned in Chapter 1. This chapter is more focused on how information is visualized and analyzed. One of the main concepts learned in this chapter is smart mapping. This is a feature that helps users choose the best way to display their information. This feature is quite helpful because it does not allow users to randomly choose symbols and colors. This feature ensures that maps are more accurate and easier to understand. This chapter also shows that there is a variety of information that can be used. This information includes counts, categories, and continuous values. By using color gradients when dealing with numerical information, one can better understand such information.
Another important concept is the significance of data classification. The way data is classified can affect how it is mapped. This helped me understand that maps are not entirely objective, as they can be affected by decisions taken in the process. Another new concept is expressions. These allow users to personalize data. Even though this part was a bit hard to understand, it helped me understand how flexible GIS is in dealing with different data.
The tutorial in this chapter required more attention to detail compared to Chapter 1. Every small step, like choosing the right field or changing settings, was very important to the final result. Completing the tutorial in this chapter also showed how Web GIS tools can assist users while still offering opportunities for customization. One thing that was not clear to me while working through the tutorial in this chapter was how different map styles might influence how a person interprets the same information. This chapter was beneficial to me in terms of helping me understand the connection between visualization and analysis in GIS.
Application:
One of the applications that can be done based on the concepts learned in chapters 1 and 2 is creating a map that shows my weekly schedule. I can input my locations such as my classes, work, and home. I can also use symbols and color to represent my activities. By using smart mapping, I can visualize my schedule and see how my time is allocated to various locations. This can help me understand my schedule better and understand my routines such as how often I go to work.
