Chapter 5:
On-premises and hybrid webGIS. The chapter begins by talking about the importance of these two features in GIS, stating how on-premises Web GIS allows users to actually use GIS within restricted situations, whether that be a lack of internet access or the necessity to use a specific internet connection. Hybrid Essentially allows organizations to keep their own information/data while still using services provided by ArcGIS Online. Although past this understanding, I was struggling to fully grasp the purpose and use of these services. Quite a bit of the explanations of different systems and services were very confusing to me. The chapter spent a lot of time explaining ArcGIS Online and Enterprise, but I’m still confused about the purposes of the two systems. It began to be a little easier to understand once I’d gotten to the parts talking about Raster and vector layers, and so on. Raster layers are beneficial for predominantly static information and basemaps. Vector layers work best as data maps that are customizable. These features seem quite similar to when we were learning about vectors and raster info in 291.
Tutorials:
The tutorials within this chapter helped me quite a bit to understand map layers in a sense. We definitely crossed similar topics to map layers.
Chapter 6:
Real-time GIS is structured as a system that works with active data to consistently update said data. I initially thought the Internet of Things (IoT) was a really odd abbreviation, but overall it fits the latter topics the chapter talks about, including the smart cities and smart homes, which can exist through IoT, and the large variety of devices that this entails. Then the ingest and process parts of IoT seem to be essentially the communication aspects of interacting with smart technologies, ingest being the understanding of input information, and process being filtering and analysing possible responses, and lastly output being the final action. The chapter then later continues to talk about several GIS applications, or systems that are beneficial to different fields. One of these systems, which we’ve touched on the topic before, is ArcGIS Arcade, which is a simple expression language. I think this is interesting,g especially just because any kind of coding or system has always been really confusing for me.
Tutorials:
In the beginning sections, I’m able to see how real-time GIS is implemented and the tools that allow for maps to be automatically updated after a certain period, one of the examples being every 30 seconds. It was also interesting to learn how to make a dashboard. It seemed to make it an easy way to track the changes in different data systems, which is great for quite a lot of things.
Application Ideas:
I wanted to leave the application idea somewhat open so I could better decide how to apply it later on in the course, but similarly to some of the things we went over in the tutorials, I would be tracking deforestation ( based on my interests specifically around an expanding city) to see the further pollution impacts of it. I do this by using some of the features we used in chapter 5, and specifically in chapter 6, the time-embedded feature layer.
