Chapter 5: The main part of this chapter is all about on premises and Hybrid GIS systems. I had absolutely no idea what it meant by hybrid GIS systems but this chapter explained it in a way that was very clear. It explains it as a multitude of of deployment models, combining desktop, web, and cloud GIS and taking the best parts of each to create what is known as the Hybrid GIS. Another thing this chapter explains is raster and vector tiles, with rastor tiles being a way of sending the maps to people in segments that all can be put back together after the transport. Vector tiles on the other hand are delivers files as many grouped vector files. and are usually put into a protocolbuffer Binary Format or PBF for short. I would be interested in learned what all goes into the 4 caching techniques mentioned in the chapter.

Chapter 6: This chapter is all about the explanation of spatiotemporal data and real-time GIS. Spatiotemporal data comes from many sources those source include but are not limited to manual data, to data collected from observational sensors and generated models.  Additionally, real-time happens during the duration of a period, either a point in time, or duration of time. Spatiotemporal data can be categorized into four groups, which include moving, discrete, stationary, and change. Another thing that this chapter deals with is IoT, which is described as the network of physical objects or things embedded with sensors and network connections  that collect data and exchange it as well. Things like taxis, bicycles, lights, refrigerators, sprinklers, biochips, security cameras and other random and miscellaneous  technological devices. Currently IoT consists of billions of sensors today and the market has reached trillions of dollars.

Potential Application:  A potential application for these chapters would be to compile an entire census for Gallia County. over the span of a couple years.

Chapter 3: Chapter 3 is all about Experience Builder. which is all about creating unique web experiences, and interesting layouts. Using Experience Builder is fairly simple in terms of the steps required in order to achieve your goal. First and foremost you are going to pick a template on what you want your experience to be centered around. Then you are going to pick your theme so that your “experience” will be clear and put together. After that you select your source data and add it to the experience this is realistically what is going to be what is shown within the application. Then you will add and configure widgets which serve as helpful little tabs within the application. After you have all of those steps done you will go back through and refine everything to make it look nice and understandable for the people who are going to use your application.  Finally you are going to take the polished product and publish it to the web for all to see and share. Something I find really cool within this chapter is that these experiences can be used to make both 2D and 3D web experiences.

Chapter 4: Chapter 4 is all about mobile GIS and what that is. Mobile GIS is really cool as you can use it basically anywhere as long as you have either wifi, a GPS system, or a cellular network. Within mobile GIS it is a lot easier to collect data as you can collect it on scene, additionally this way of moving information is less prone to mistakes than the transfer of surveyors drawings all the way back to whatever lab that they work out of.  Mobile GIS is literally on an app on your phone that’s really cool. This. app allows for overall ease of the collection of data.

Potential Application- You could use mobile GIS to map out a high foot traffic area while experiencing that traffic first hand.

Chapter 1- I learned that Web GIS is easily more accommodating than desktop GIS since it has global reach, low cost for users, large number of users, and better cross platform capabilities. Meaning that data transfer is easy to do among the users of web GIS. When it comes to web GIS “The Science of Where” is what it is all about, whether that be places on a map or data points within a summary GIS is able to do that. For example GIS is used in all sorts of fields; remote sensing, crowdsourcing, weather, 3-D visualization to name a few. Additionally this chapter explains how you can import data into the application rather than having to to through and type all of your data points one by one. Additionally much like with desktop GIS you are able to make legends and charts and other graphics that explain the dataset being represented. Symbology is another concept within this application that is the same as desktop GIS, which is always fun to be able to customize the symbols and really make the map feel like you have had your own spin on the data set.

Chapter 2- Chapter 2 is very quick to explain the use of feature layering and smart mapping, listing a whole list of different smart-mapping styles such as heat mapping, mapping based off of color and size, dot density maps, etc…, and it explains the differences and practical uses of these mapping styles. Pop-ups are another feature that existed in desktop GIS as well, but they show geographic information and insight just by clicking on the corresponding location Chapter 2 also gives the blueprint of GIS applications those blueprints consist of the base map, the information layers that qualify what the map is trying to show to the readers, and the tools in which you need to use in order to actually assemble the map itself.

Potential Application- A potential application that could be used with this information is a map showing how the polar ice caps have melted from year to year.

Hello, my name is Braidy Duncan, I am a sophomore here at OWU majoring in environmental studies and for this week I scheduled a meeting with Dr. Krygier and took the quiz for Geog 292.

Additionally, all of the other parts of this assignment I did when I was in Geog 291.

When I did the tutorial it was very similar to the one in Geog 291, as it taught you how to zoom in and out, add layers/data to your map, as well as bookmark things to name a few of the similarities. Overall, the tutorial was insightful and allowed me to be confident in going forward with this class.
