My Name is Carl Mazabras and I am a Geography Major with a Business Minor. I am from New Canaan Connecticut which is 45 minutes outside of NYC. I am on the lacrosse team here at OWU and along with playing lacrosse some of the things I like to do are fish, work, play video games and spend time with my buddies. I have been interested in GIS ever since I took my first class with Dr. Rowley and have even completed  a couple of GIS projects throughout my years here at OWU.

Throughout the reading I was able to see a lot of similarities in the breakdown of GIS with how the software works on the computers. The one area that stood out to me was the different layers we are going to have while creating the maps. The three visible layers in the first chapter are land use, land parcels and streets which is very similar to ARC GIS. Last year in the 112 class with Dr. Krygier we did a state population map with many different layers. Those layers consisted of roads, county boarders and state outline. Each of those layers were shown in the hot bar on the left first of the GIS software which could all be turned off or on it just depended on what we wanted to portray.  To me this chapter is a great start because it really explains how the software will work without really telling you this is how the software works. I feel that people without any knowledge of ARC GIS will see the relationship from the book when they start to work in ARC because the entire software is based around layers that can be turned off and on to show different maps without changing the area being mapped. Layers can be showing different data or you can even put the layers into a timeline and show the history of an area. In 112 we had 12 layers each layer was in intervals of 10 years and the data linked to each year was the population for that county. We were able to show the population change and growth in the last 120 years working on one map with a ton of different layers.

You can use GIS to map out areas for potential solar farms and I have a huge interest in renewable energies so this would be right up my ally. You can use drones to get perfect pictures of the buildings or areas that you want to put solar down. Below I have a map of solar insolation which is showing the wattage of energy that is hitting in the colored area red being high and blue being low. Another way you can use GIS is to map an area for construction to see what the land is made of by doing soil composition testing which has been done a larger scales but not yet done at a small scale like a singular property or block.

Hi, my name is Jay McConkey. I’m from Cambridge, Ohio and I am a senior and an Environmental Science and Geography major. My academic interests include GIS, remote sensing, mycology, and plants. My other interests include reading books or manga and running. I have recently started a crochet kit, so maybe I’ll develop a new hobby this year. It’s been a while since I’ve taken a GIS class so through the course I will be brushing up on my previous GIS skills while aiming to master new ones as well. 

Having experience with ArcMap, I wondered how the author would describe GIS to the unfamiliar. The opening passage surprised me as the reading begins expanding on the uses of GIS and how it is utilized by many people in many ways. I honestly didn’t know that Starbucks credits its success to the use of GIS software, but it doesn’t surprise me given the scope of what can be done using GIS. This makes me ponder other potential uses for GIS, other than the examples Schuurman describes (landscape architecture, surveying, ect.).Furthermore, it is interesting to read about the origins of GIS and how at the early stages the biggest limitation was technology. Given how much computing power has improved in the last couple of decades, it is no surprise to see the scope of GIS advance just as much The origins of GIS are framed just as interestingly. I had no idea just how messy the origins actually are, but I really like Schuurman’s analogy of GIS to a calculator. It makes sense since modern GIS has some many tools and built-in calculations, but you still have to know which calculations to use and when. The fact that these techniques are more accessible, broadens their potential application.

One aspect of GIS that is brought up is the power of imagery. Schuurman states that GIS commonly refers to ‘geographical information science’ as well as ‘geographical information systems.’ I feel like, at this point, GIS is so complicated and involved in so many sciences that it is impossible to fully define in a single sentence. Schuurman elaborates on this later in the readings when she states that GIScience is used to provide justification for GISystem functions. Schurrman also talks about how GIS digitizes physical data which is therefore manipulated in a way that the user interprets the world. This reminds me a great deal of one of my first GIS assignments given by Dr. Rowley. He had us use remote sensing to classify a GIS satellite footprint as disturbed and undisturbed land. We all classified our maps slightly differently according to our own personal biases. This made each of our maps slightly, or wildly different and showed us how GIS data is interpretable. Furthermore, emphasis is placed on the importance of visuality and how humans use visuals to comprehend concepts or statistics. The subject of colors, textures, and symbols in map-making is fascinating to me and is something I would like to learn more about. Another interesting inclusion that Schuurman describes as an interest of GIS users is whether GIScience is inherently gendered. This fascinates me, because I do not fully understand how a geographical system could be gendered, but I have a feeling it stems from past geographers who are mostly male.

GIS Applications:

The first GIS application I looked into was ground penetrating radar, which is used for archeological studies. The source I found described a new processing tool, which automates certain processes and identifies anomalies. With the ground penetrating radar and GIS, the team was able to analyze buried structures. The image below is an Ancient Roman theatre that is currently underground.

One of my academic interests is mycology, so I looked up related GIS applications with fungi and found a study using GIS to assess the distribution of fairy rings. Overall I found the study interesting and I hope to come across more research that uses GIS to study fungi. The picture below was taken from an airplane and includes the fairy rings are identified.

Hello,

My name is Evelyn VanderVelde, I am a senior majoring in Environmental Science with a minor in Botany. I hail from Holland, Michigan, and part of Zeeland, Michigan as well (duel households for the win).

In Chapter 1: “GIS a short introduction” by Schuurman, GIS is defined in many ways, primarily by what its intended use purpose entails. The research that uses GIS morphs the format to each individual user, so a city planner uses GIS much differently than a biological researcher. “It is not a piece of software, but a scientific approach to a problem.” The question of how to best use GIS is based on the question of “where” the data is and “how to encode” the data. GIS is also inherently visual in its applications which creates the importance of color and symbology within this new mapping field. “Visualization is used to manufacture meaning from data, through rendering it in image form. GIS incorporates ongoing research into geographic visualization but, more to the point, it is based on the very principles that have recently brought scientific visualization to the fore” (Schuurman, 8) It’s also stated that people reason much better with visuals than with other types of data that is more numerical or literary. I found this interesting as previously in my other GIS class we always focused on having visually enticing and simplistic in its interpretation for all types of viewers, but I don’t think any definition like this was brought up. It makes a lot more sense to me as to why the visual components of my maps on GIS were so heavily stressed previously.  The blurred boundary between definitions of GIS is confusing for me as well as there is no set criteria for which I should create my maps. This conflict though could be helpful as it gives more liberty artistically.

For this link, I looked up swimming pool detection and found this link via the ArcGIS developers themselves. I was given the coding to add swimming pool detection to my maps and the infrared needs in order to be able to label uncovered pools in residential areas. The image to the left shows multiple images that were used to train the ArcGIS system in finding swimming pools in residential areas.

Howdy!

My name is Gabriel Chlebowski and I am a junior zoology and environmental science major from Toledo, Ohio. Some of my interests include animal behavior, geography, music, sports, and kayaking. GIS has always been super fascinating to me since I have always loved maps growing up, so I am very curious about this course to see if my knowledge of the discipline can be expanded upon 🙂

One of my favorite sections of Chapter 1 was explaining the human condition that it is easier for people to discern information through visual displays like maps as opposed to more textual approaches of displaying information like in tables.  They point to a pretty straightforward but also slightly comical example of showing tuberculosis rates in a table format with percentages next to state zip codes. As strange as it sounds, without mapping software or a skilled cartographer, such data would be left in that format, which is very indigestible in my opinion.  In addition, I did not know that not only do people “reason” using images, but such is processed differently in the brain that text. I think that the way that data can be processed via images is very special and really gives GIS great purpose in the realm of data analysis. This was especially true in the example of John Snow’s Cholera maps, a story in which I found extremely fascinating. The data by itself was not ample enough to draw any conclusions in where the source of the sickness arose, yet the use of mapping allowed Snow’s intuitions to lead him to the holes in the data, allowing for follow-up questions to reveal that the public wells were at fault. These types of stories are one of the many reasons why I find this type of data analysis so interesting. Maps can offer extreme amounts of information about a place or event that is much more in-depth and layered (pun) than a table with a contextual description. It takes extreme care and large amounts of precision to work the data into the visual in the correct fashion as to be the most presentable and apt as possible for the intended audience. Briefly mentioned in the chapter, the use of specific colors when discerning data is another way in which visualization can lead to more precise analysis, which is an area that extremely piques my interest.

 

The first of the two GIS applications I found was an older report on seagrass abundance monitoring in the realm of dugong population health. The map accompanied from it is very old (article published in 1993), but it is very informative on the locations of seagrass off of the coast of Australia. The subject area is of interest for me as I wrote a research paper on factors that negatively affect dugong population size, in which seagrass availability and quality were of the upmost importance.

The second application is a type of online armadillo occurrence tracker called Armadillo Mapper (AM). This GIS tool automatically makes a range map of armadillos in the subparamo habitats of Peru based on user online input that shows on the map as potential occurrence. This is important to the knowledge of the hairy long-nosed armadillo (Dasypus pilosus), as their compiled map shows a larger range than the established one by the International Union for Conservation of Nature (green circle on both maps).

Hello! My name is Lily Bechina. I am a freshman environmental studies major. I am from Chicago, Il. I became interested in the environment over covid lockdown. I found the effects from everyone staying indoors (very little travel) for a year very interesting. I went on to take an environmental studies class my senior year of high school and really enjoyed it. 

Schuurman ch.1 Response

I found the reading from Schuurman very interesting. I really didn’t know anything about GIS and how it works so the reading was very helpful in understanding what we will be working with in this course. Although the diction could get technical at times, I still understood what I was reading and was able to take a lot away from it. The comparison made between GIS and calculators helped me to understand the uses and benefits of GIS technology. GIS must be used with an understanding of what is being modeled and how it is being done to be used properly. 

Learning about how people use GIS differently and see different purposes/functions for it was eye opening to how complex the technology really is. I enjoyed reading about how GIS technology allows for unspecific data to be utilized and interpreted.  

For GIS being such an intricate piece of technology, it produces something that people form their opinions off of in a more abstract way. Schuurman describes it as “unscientific” while also pointing out that forming opinions based on the visual aspect is supported by some researchers. 

Although this is a small detail, I appreciate the author using the word “she,” when making a statement about GIScientists in general. The author is a woman herself, but it honestly caught me by surprise. Furthermore, I enjoyed the mention of GIScientists’ questioning if the technology is gendered and even touching on the social side of GIS technology. That dynamic is something I would love to learn more about.

Reading about GIS as a language that is much harder to understand and use than the English language helped me to see more of what exactly GIS technology has to offer. It honestly made me somewhat nervous about my own use of GIS because learning and understanding a new language is not quite easy. 

GIS Applications

One GIS application I found is for disaster management. Technology is used to study disaster patterns over time. It helps to understand the ways in which certain areas of land are impacted by disaster and better help to reduce damage in the future. 

Another GIS application I found is for water resources. This application helps to predict where pollution may come from. With that, the pollution can be hopefully avoided. It also helps to watch the flow of polluted water and infer what that water will go.

Hello, I am Keegan Floyd. I am a freshman planning on majoring in Genetics, with a possible double major (or at least a minor) in Data Analytics. I apologize for the picture; I put a mask on in 2020 and haven’t taken it off for the very few photographs taken of me since, so you get this picture of me hiding in my closet. I am taking GEOG 191 for two reasons; first, in an effort to broaden my academic horizons to see how different fields intersect with my chosen areas of interest; second, this is a useful skill set to have if I lean more into bioinformatics in my future career.

I found the first chapter of Schuurman’s Introduction to GIS to be surprising, as my knowledge of GIS and geography, in general, was almost nonexistent before signing up for this class. I was not aware that a system designed for geography could intersect with so many other scientific fields, influencing large parts of my daily life through its importance in agriculture, urban planning, and healthcare. The uses of GIS in public health surprised me the most; it just never occurred to me that it is necessary to use geographical data to define and analyze health at the population level.

 I appreciated how much detail the chapter included on the two “sections” of GIS: GIScience and GISystems; I believe that portion of the chapter deepened my understanding of the subject by showing how the two intersect via examples of both in day-to-day life. I am curious to see which of the two sides of GIS we learn more about in this course, though if I had to guess, it would be GIScience due to its position as the underlying theory behind GISystems.

This passage encouraged me to think about the applications of GIS within my major, which lead to my fascinating discovery of just how much population genetics relies on mapping systems to analyze data and predict research outcomes. This fact reassured me that this course will be beneficial in my future endeavors despite how different it is from my typical major-related classes.

This chapter opened my mind to the idea that GIS is not a simple information system, as the name suggests, but rather a broadly defined concept with more applications than could possibly be included in a single definition. I am looking forward to wrapping my head around this system throughout this course. Overall, this chapter has helped me gain a better understanding of what I need to know and what questions I need to ask to succeed in this course.

I used google scholar to look into the applications of GIS concerning genetics and came across an article about the use of GIS technology in landscape genetics. This article talks about utilizing GIS to map genetic variance in several different species across a large area to reach a level of visualization of data that was previously much harder to attain. These maps can be used to find patterns of gene flow within and across species.

My second topic of interest was GIS in relation to public health. I found an article discussing how GIS is particularly useful in the prediction of parasitic disease spread through the mapping of parasite appearances and the population density in an area. There is no accompanying map for this article.

Hi! My name is Jonathan Munroe and I’m a junior from St. Louis, Missouri. I’m majoring in geography with a minor in music performance (violin). I’ve taken quite a few classes regarding GIS but I’m excited to take this course specifically on ArcMap. After graduation I’d either like to work for a nonprofit urban planning agency doing neighborhood revitalization without displacement or work making maps out in the woods for the forest or national park service.

Schuurman Chapter 1- Introduction to GIS: I found this passage very interesting, as I’ve read about the history of map-making and remote sensing but I’ve never learned about the history of GIS. The program itself is so versatile and especially in today’s age, it’s widely popular and sought after. As an example, last year when I worked at the Flying Pig I was talking about my major to a customer who worked for Nationwide in Columbus. He told me that if I got a degree or certificate in GIS I should come to him and he’d have a job ready for me. While insurance isn’t a field I’m interested in, I think the story speaks volume and adds on to Schuurmans emphasis on how popular GIS has become in recent years. Another thing I found fascinating was his topic of visualization where he said “visualization is used to manufacture meaning from data…people are able to discern information from visual display with greater facility than from tables or printed text.” I’m a visual learner myself and think my love for maps stems from my availability to understand the data. Schuurman further proves his point by saying that “people ‘reason’ using imagery. GIS can better connect, market and convey any information, which is why it’s so sought after in the job market. This reading has made me excited to take this class through the semester and become more knowledgeable and familiar with GIS, helping me excel my research skills, resume and general knowledge.

For my map, I chose to look at the racial segregation of Cape Town, South Africa with the failure of the Group Areas Act of Apartheid. I chose this map because I’m currently writing a TPG to visit Cape Town regarding racial housing segregation in comparison to the Red Line Policy of the United States. This map shows the racial composite of Cape Town using census data from 2011.

Hi Everyone! My name is Eliza Richardson, and I am a senior majoring in Environmental Science and International Studies, from Lakewood, Ohio. I love to cook, workout, and spend time outdoors doing anything from hiking to sand volleyball to laying on the beach 🙂 I am excited for this class because I have always wanted to grow my GIS skills, and I think it would be very beneficial for me moving forward in my career after graduation. After graduation I plan on taking a gap year before attending a masters program for environmental policy and sustainable development! 

Schuurmans Chapter 1- Introduction to GIS exemplified how versatile and important GIS can be in the academic, research, and professional world. One of the great things about GIS is that it can be used for such a wide array of topics, that it can serve almost any field of study. Schuurman points out that a significant distinction of GIS is that it is more about “spatial analysis” as opposed to simply “mapping”. Categorizing this kind of work as spatial analysis allows us to think more externally about how we want to be expressing certain kinds of information and data, and how to most effectively. However, Schuurman explains how GIS wasn’t always so interdisciplinary. At the beginning of its development, many people argued about what was the proper use of the technology – should it be used by those who are looking to analyze spatial data, or should it be used by those who are looking to print physical maps? I also thought it was interesting how Schuurman talks about how the development of GIS is important for both social and technological developments. With all of these varying views on the implication of GIS in the world, I think that this is one of the reasons why I am interested in learning more about GIS; it is so versatile in every field, and can be used in more ways than one would ever picture. 

The concept of GIScience is really interesting to me. Often times, when I have struggled with creating material in GIS before, I feel as though the reason why I had struggled was because I didnt completely understand the concept of what each step was doing with my data, therefore I didnt comprehend how to connect it all together, and know what step to take next. I think that if GIScience was briefly touched on when learning about this system and the projects we will be doing, I think it would help people to better understand why they are performing the functions they are in GIS, and will help them apply their knowledge to future projects.

In looking at GIS applications, I looked at the correlation of giant panda populations and the amount of deforestation and human impact in areas of giant panda habitat in Central and Western China. I found that GIS can be used to map anything from the density of mammal populations, to the suitability of habitat for giant pandas, to the areas of the region that are experiencing the greatest effects of human activity such as the building of roads through dense forests. Figure 6 from GIS application in evaluating the potential habitat of giant pandas in Guanyinshan Nature Reserve, Shaanxi Province, shows the level of human impact from residence, to roads on a nature reserve for giant pandas in the Shaanxi Province.

I’m Lauren and I’m from Canton, Ohio! I’m a freshman majoring in Data Analytics (and thinking about adding geography as my second major!) I love to ski, kayak, hike, camp, and play tennis in my free time.g

I thought the Schuurman Ch. 1 reading was very interesting, especially because of all the applications of GIS it described. I especially thought the applications of water reservoirs and natural gas fuel lines were interesting. I was recently at ODNR, and I got to talk to them about how they use GIS and data for the Canalway and other water sources in Ohio as we are a part of both the Lake Erie and Ohio River watersheds. So, that portion of the reading really helped me tie that experience and the course together. On top of that, the reading also references some applications I never would have considered at the beginning – like its use in Starbucks stores! I also thought the history portion of the chapter was engaging. Learning about the history of using tracing paper and a light table was insightful into the very beginnings of GIS. I also found the part about the original resistance to GISystems and how it eventually became accepted without a second thought over time in the “black box” portion of the chapter. I also was surprised by the distinction between GISystems and GIScience. I did not know that there were two terms, but I appreciate the explanation of how both are important and work together. In this regard, I thought the notion that GIScientists constantly question the efficiency of the GISystems algorithms was super important. Algorithms can be so flawed when we make them even if we don’t notice them at first. In, high school I wrote a report on racism in the medical field and found that with organ donation algorithms, they favored white individuals over half the time. This always makes me think about how important it is to constantly keep an eye on and reevaluate the algorithms we make because often they include our own underlying biases, and we implement them anyways. Thus, I appreciate the aptitude of the book to explore this same notion and its truth for GIS algorithms.

The first GIS application I looked at was food deserts. Canton is a food desert, so I have always been interested in how to effectively view the impacted areas. Last year, a researcher from Ohio State came into one of my classes and showed us the maps he had compiled on Canton as a food desert. Thus, after I read this chapter and thought back to that class GIS came to mind. USC’s spacial science institute had a whole website on how they use GIS to study food desserts. They have mapped everything from the availability of produce and distance and rigor of the path it takes to get to a store. They cross-apply this with maps of income levels and people who own vehicles or other means of transportation. In one study done in Chicago, their researchers found that low-income neighborhoods had significantly less access to food and more poor-quality food compared to upper-class neighborhoods.

Another application I came across was for ski resorts. The application is called Snow Mappy and it was created when the founder decided she wanted a better way to view ski resorts than just a paper map or a sign at the top of the hill. Mappy uses GIS to map things like velocity, and skier speed on certain trails by level, density, and concentration of skiers on certain trails. The application can be used by skiers to track their location and different resources on the mountain as well as the resort itself to track its staff and decide if certain trails need to be added or changed based on where people ski. The map below is the map that displays skier density on trails based on skill level:

Hello, I am Connor Skidmore from Bellefontaine Ohio. I am an Environmental Studies major and a member of the Cross Country and Track teams.

In Schuurman Ch.1 the author begins by discussing the wide range of modern uses of GIS. They describe GIS as a system used by many but not understood for what it is to the public. The history of GIS seems very confusing because it started as a standard practice done by cartographers that quickly became a digitized field. All around the same time, people from different parts of the world started to make similar systems that today are the foundations of the modern GIS system. The author states that GIS would have been inevitable without interest from Geography but I do not see how that is true because the base field of understanding the information is needed. Even the definition of GIS is very convoluted based on the person and their needs with the system.

This chapter as a whole gave me the ability to understand that GIS is more of a broad net that covers a ton of information rather than one stable thing. GIS is shown in the chapter as a broad and sweeping term that is applied to certain things that by themselves are convoluted. Two people can both use GIS but come up with two very different understandings of the software and its use cases. To me, the history of GIS seems to be a known yet unknown variable based on the chapter because if so many different fields and researchers were doing the same things at the same time how did they finally decide to make the broad sweeping net? This is in my opinion why GIS can have so many different definitions and use cases because the history of it comes from many different people who at the time were doing very different things.

I enjoyed reading this chapter though because it provided a unique into GIS. The chapter also showed how GIS itself is confusing to understand as a whole.

Since I have an interest in City Management I used the keyword City in my search for GIS applications. In my first article, I found that GIS was being used to find if rooftop wind turbines were feasible in Bari, Italy. Since Europe and the Bari have had increasing discussions in “Smart Cities” and energy the study was born to find if rooftop wind turbines were feasible.

In my second article, it discusses how GIS would be used inside of “Smart Cities” which are described as cities that are on the cutting edge of technology and developing new technologies. These cities would use GIS to optimize planning throughout all sectors of the cities while the businesses that innovate in these cities would use GIS to create new technologies.
