Chapter 3-

• So now we have web experiences and storymaps. I wonder if there’s situations where its best to use one over the other, or which one is best or a specific situation?
• This chapter was a lot shorter than the other ones, and I appreciate focusing on only one topic instead of multiple, I think it makes the concept more understandable.

Tutorial 3-

I can’t figure out how to get the 3D map. You can’t search for it, and I can’t find the button to make the 2D into 3D if there even is one.

Well, there’s no URL available for me to type. So I can’t do that either. Annoying.

I did the rest of the tutorial to the best of my abilities. I think it’s going to take me awhile to fully get this web experience thing because there are a lot of aspects to it, and since the right and left ribbon layouts are similar to the map viewer ones, I keep on getting confused and thinking one things in one spot when its not.

Chapter 4-

• I’m interested to learn about mobile GIS because of its different uses. For any surveying this is a great resource and I wonder how easy it is for a common user to use it for that or other easier concepts.
• Having different hosting layers, one for group members to share and edit, and another for the public to see, without one seeing the other, is a good idea and makes this concept much more applicable for wider audiences.
• I also like the different approaches that can be used for different reasons and audiences, like for websites only or for apps only on mobile.
• Being able to literally create assignments for field workers is really useful. I used to work an admin job for a restoration company and I wonder if they could’ve made their own software for assigning jobs like this.
• I feel like the ARCGIS indoor mobile app would be of good use on a college campus.

Tutorial 4-

Based on the chapter, I was missing information on certain questions so I couldn’t complete it yet again. Because again there were so many little pieces missing that added up and overall the instructions make no sense.

I had really no problems otherwise. Just me being annoyed at how the chapter is for me.

Overall, these were all really interesting concepts to me! It just sucks that I wasn’t able to comprehend them all the way right now. I’ll definitely look into it for later though. I also did the Delaware Data Inventory in 291 so I don’t have to worry about that right now.

Chapter 1-

• I really like how Web GIS was designed with every user in mind, and making it accessible for people who aren’t familiar on the subject or the best with technology to use.
• I also appreciated a definition of GIS- the science of locations, and the explanation that the “science” is both GIS as a science and GIS being used for science. A bit more complicated than I would’ve originally thought.
• When I think of who uses GIS, I think of Government Orgs, like 911, businesses, and such. The fact that it can be used by whoever to help decide things like shop, eat, stay, and get from place to place is interesting.
• Johns Hopkins using ArcGIS Online to make a real time Covid tracker that is widely used and sourced is actually really cool and important.
• The attachment viewer seems like a good way to quickly and easily provide information, and is easily accessable as well.

Tutorial 1-

I’ve learned that getting the data will be a little different for me because I’m using a Macbook, and right now mine is being glitchy with uploading files for some reason, so I have to drag them in to upload, like the picture shows.

Once I was in the map viewer, I started having some trouble. I’m used to ArcGISPro from GEOG 291, so everything being in a different place took some getting used to. There are so many buttons on those side tabs that they’re confusing me a little and I’m having trouble locating certain things.

As you can see in the screenshot, sometimes the tutorials are missing information for me. I’m not sure if its the format I’m using or what. So take that into consideration when reviewing my work.

I can’t seem to select the “instant apps” button, even though I am clicking it, so I am unable to do 1.4.

Chapter 2-

• Arcade seems really complicated. Expressions (I think thats what those codes are) are things not easily comprehended to me. We had to deal with a little bit of that in 291 and I was confused, so it’ll be interesting to see how much different (and hopefully easier) this web version will be.
• I am familiar with Living Atlas already from 291. I really like how easy it makes to find a bunch of information types, including basemaps, boundaries, etc. I’ve found that it makes map making so much easier in the past.
• In 291 I found storymaps to be a different than usual way to get information across. When I made one, it was a bit complicated to make, but since it acts like a mini website I’d say it’s easy enough in the long run. I wonder what ways you could potentially use storymaps without maps, like with just images or something.

Tutorial 2-

Again, the tutorial is leaving out parts, as seen by the screenshot below. I made the Y offset 5, idk why. Made the opacity 25 too since I wasn’t given any directions. I just thought it looked nice.

I am very surprised I managed to do that coding section. Some things seemed to fill in for me instead of me manually having to do them so that helped.

I actually really liked the create a map portion of this tutorial. I found it to be very useful for figuring out how the map viewer works with a relevant and interesting topic.

Of course, I can’t find the data for the storymap. Anywhere. And what they’re telling me in the tutorial is slightly confusing. Typically I can infer but its nowhere. Lovely! It’s possible the data is from an already existing map anyways and I just didn’t know. So yet again, I can’t do a section. Sorry.

 

Overall, I think these two chapters and tutorials are a good introduction to what can be done with WebGIS.

Chapter 3: 

• This tutorial was harder to understand. I don’t know if it was the book or the program. However I was able to work with the program and get some information from the tutorial. Personally I am finding these tutorials harder than the desktop version maybe its because the small screen on my computer or the book is not updated as it should be. 

Chapter 4: 

• This tutorial was interesting. I liked seeing a different program that stems from ArcGIS. Again some of the information wasn’t clear so I didn’t get the full understanding but made it through the majority of the tutorial. I thought it was cool to see the new applications and a new way to express data and gain more knowledge about topics through surveys.

Chapter 3 

One cool feature that I like about WebGIS is the variety of ways that users are able to customize their experiences. One example of this is what WebGIS calls Experience Builders to build apps. Experience Builders have multiple steps with options in order to utilize app building with them. The first step is to either pick a premade template or to start building your app from scratch. If  you choose to use a template, you are picking to use what is essentially a premade app layout with preconfigured widgets (placed in certain areas with certain styles). If you don’t choose to use a template, you would do this step from scratch. The next step in using an Experience Builder is to then choose a theme for your app. This theme will be a preset style for how your app appears. However, one thing to note is that the theme will not impact the layout of your app. After choosing the layout and theme of your app, you then begin to add data. This data can be anything. It can be 2D maps, 3D scenes, or even feature layers that you create or import from elsewhere. Once your data is imported, you then will configure your widgets. When using Experience Builders, you have the option to use two different kinds of widgets. One of the options is a basic widget, and the other is a functional widget. After adding the widgets, you then add the relevant data sources, styles, and actions. The next step is to refine layouts for all of the devices, this is simply just making sure that the app will be correctly formatted on any device that it is used on. The final step is to just save, preview, publish, and share. 

For 3.1 the URL did not show up in the online book, so i couldn’t insert the proper image 

I also had trouble linking a section to the Data Summary Views Navigation; due to this issue, I was not able to successfully complete 3.3 

Chapter 4 

I think the fact that WebGIS is mobile to be used on a phone is really interesting. ArcGIS is only able to be utilized on a desktop, which was really hard for me during that class. However, WebGIS can be accessed anywhere, including phones. Being able to be mobile gives WebGIS a lot of advantages. For example, it is easier for the software to utilize location awareness. It allows for the use of GPS, cellular networks, WiFi, bluetooth, compasses, and way more. It also allows for the collection of data to be done easier. It erases the human error risk with paper data collection. ArcGIS does this as well, but instead of using a desktop, users are able to just use their phones or other mobile devices. There is also the added benefit of live connection to mobile networks adding near-real-time information. WebGIS has a greater ability to monitor spatial and temporal information. Being mobile also allows the software to be able to be used by more users, therefore, there is a greater demand. Some examples given in the book of devices WebGIS works on are: smartphones, tablets, smart watches. These features are compatible with a number of different operating systems as well, these include Android, iOS, and Microsoft. This is different from ArcGIS as it only worked on Microsoft/Windows. Along with this concept, WebGIS also makes it easier to communicate. There is an added feature of communication and collaboration with professionals and consumers.They are able to communicate in many ways compared to ArcGIS, such as voice notes, texts, photos/videos, email, social media, calling/video calling. There is also the options for wireless communication. This can be done via Bluetooth, Wi-Fi, 5G networks, satellites, etc.

IDEA:

I think for my final project chapters 1-4 app, I want to create an app about educating the users about something within the Delaware Data, and then create a survey about when they want to include more or have it act as like a quiz and have it linked on the app

Week 3

 

Ch. 1

     Web GIS to me is a little more user friendly as opposed to desktop GIS. Web GIS is more widely used by scientists and even governments to collect data and share information. This first chapter is meant to show you how to develop a Web GIS app, but I’m not entirely sure how to do that yet. 

     WebGIS is meant to be an easier way to work with GIS from anywhere. I find this application easier to work with than what we were doing in 291. There are some similarities, but this one seems just a little bit easier to understand. 

Ch.2

     This next chapter goes over the map layers and what they are. The “feature layers” are used most often to show similar points of interest like buildings, roads, and cities. Hosted feature layers are the most used operational layers (they are a reference to feature layers stored in the GIS system). 

     By reading this tutorial (and googling for confirmation), you’re able to upload your own feature layer data from ArcGIS in the form of a shapefile like we worked a little with in 291, a CSV file, or a file from the geo database. You just have to click on “new item” on ArcGIS online content and upload from google drive. This looks easier to do than I expected, given that you have the files and such ready to upload.

 

notes:

• C1
  • in 1.3 number 4 is that I do not see a basemap that is labeled “Community Map” which is strange as I remember using that same basemap for some story maps that I have recently made. I decided to use the “Streets” basemap instead as it looked like the closest one to community map.
  • The configure pop-ups button is just called pop-ups in the settings toolbar
  • It was pretty cool making a web map that can previewed with mobile phone dimensions, especially considering how useful it could be as so much information in the past 5 or so years has been consumed simply on our phones

• C2
  • Page 41 shows all of the smart-mapping styles; I love these so much i cant put my finger on why but they are just so interesting to read and especially to play around with them when deciding which one to use to represent data and even what type of data suits each style the best
  • 2.1 number 6 there is no state location type, only a region location type that uses the state field instead
  • I am not a fan of the color theory of red being gains, as i often see in media that red can also effectively be used as losses and blue for gains as well, instead i like a color like green for gains
    • As protest i changed my gain arrows to pink !!!
  • 2.3 number 5 globals is not a button, it is called profile variables
  • Despite backtracking the settings and rechecking the csv sheet, the bargraph in the city pop-up menu does not want to show, even when i selected it in the configure chart, it shows the space where it should be but it does not show any information
  • 2.5 number 21 there is no place map button, just click save
  • 2.5 number 24 there is no map action option in the block palette, there is adding a map and media action but no map action
    • Oh okay it wants us to use the media action button!!!

My story map!!!!: https://arcg.is/1ubG1n

An application that could be created from these two chapters would be a story map based on a compilation of birding trips and what you saw, heard, and felt during the trips! Maps could be inserted into the story map using spreadsheet data of bird sightings over an extended period of time with location data on where you went birding, where you spotted specific birds, pictures of the birds (or even if you got your own in the field), a description and overview of the specific birds that you saw (linking to other informational websites), and possibly a comparison to the amount of birds that are commonly and uncommonly found in the areas versus what you saw!

Point data on where specifically you saw each bird based on external devices like ebird.org or by simply placing points on a map and running a story map through each of the points, explaining the amount and different types of avians seen at each location, and maybe a link to recent research about the birds hast were seen or just links to website explaining their range or behaviors in greater detail.

 

In the first chapter, I learned how to create layers from CSV files and add attachments to them, as well as how to add an ID field to a layer to display photos in organized sequences. I also learned how to add feature layers in Map Viewer and configure its style and pop-up.  This tutorial also taught me how to transform web maps into web apps using the attachment viewer template. I like how the app I ended up creating was user-friendly and accessible across platforms. 

In the second chapter tutorial, I learned how to create a feature layer from a CSV using geocoding, and how to configure layer styles on the visualization tab using smart mapping. I also learned how to use ArcGIS Arcade to configure layer pop-ups and how to add images and charts to these pop-ups. Finally, I created a story map and added swipe blocks and an express map

Hi, my name is Auzlynd, I am a junior majoring in environmental science and biology.

I already have an OWU ArcGIS Online account from taking the Geog 291 course earlier this semester. 

In the My Profile section, the projects I did in 291 are saved there. The training section shows courses you can take to gain skills in web mapping and analysis and The ArcGIS blog section shows what is new in ArcGIS Online with various other articles. 

From the reading “Get Started: What is ArcGIS Online” I learned that ArcGIS is a cloud-based mapping and analysis software with many uses like making maps and analyzing data. It also serves as a facilitator for sharing and collaborating. You can create maps, scenes, apps, and notebooks and manage the data you explore and analyze. This software can be used in field activities as well as configuring sites and provides tools for accessibility. 

The course “ArcGIS Online Basics” helped give me a solid foundational understanding of all the features of ArcOnline. I have attached some screenshots.

Using ChatGPT I looked up how hiking or camping could be applied in GIS. I learned that GIS can be used to make maps of trails used for hiking and these include useful information like difficulty, trail length, elevation gain, and points of interest. This is helpful so that hikers and backpackers can plan hikes and navigate trails. Here is a source I found that I thought was interesting: “Planning of recreational trails in protected areas: Application of regression tree analysis and geographic information systems” (Aleksandra M. Tomczyka, Marek Ewertowskia)

Hello, my name is Jack Zimmerman, and I am a senior majoring in Quantitative Economics. I took this course as a general requirement, but I am interested in data analysis and thought this course would be fun. Additionally, my primary area of research is real estate, so I thought this would be an excellent complement to my existing knowledge.

Looking Around:

The overall site layout on ArcGIS seems fairly straightforward and intuitive. I explored some layers created by other students and added them to the map. Data management seems to be something I need to reconcile later.

Getting Started: What Is ArcGIS Online

I spent most of my time in the “Manage content and data” section. Looking at the “Perform analysis” subsection. It seemed interesting, but I think I will stick with doing analysis with R Studio. The primary issue was that data must be publicly available, which is something I can’t do with the data I want to use. The second issue is ArcGIS’ credit system. Doing analysis requires credits, and I have already used all of mine to import some data. Next, I looked at the “Manage content and data” section. Overall, this section was pretty unhelpful, and it just told me stuff I already knew. A few of the embedded links inevitably led me to some helpful articles on data management. However, I still need to do further reading.

Web Course: ArcGIS Online Basics

This was okay. I found myself just using the book and just skimming over this.

 

ArcOnline Applications:

I know I want to do something with real estate, so I looked up papers on real estate-based applications. My goal was to find papers on methods and processes for handling data.

Paper 1: Laban, K. N. (2017). Integrating Gis and Real Estate Management Systems to Market and Manage Facilities on the Web (Doctoral dissertation, University of Nairobi).

The first paper I looked at, “Integrating GIS and Real Estate Management Systems to Market and Manage Facilities on the Web,” discussed combining real estate management systems with GIS maps. This paper is super detailed (121 pages detailed) and includes information about cleaning and analyzing data. Below is an outline of the process used in the paper and one of the websites created.

Paper 2: Kwon, P. (2012). Analyzing Southern California Residential Real Estate Prices: A Spatio-Temporal Approach.

The second paper I looked at, “Analyzing Southern California Residential Real Estate Prices: A Spatio-Temporal Approach,” analyzed both spatial and temporal autocorrelation patterns in real estate data. The approach taken by the paper to analyze the data seemed a bit too simple but was nonetheless interesting. I think the paper also made a few mistakes in how they clustered the areas and conducted the tests, but they somewhat fixed it in the end. The paper used Moran’s I as the metric to measure spatial autocorrelation. I hadn’t heard about Moran’s I, but I did look it up, and it is very similar (mathematically) to other correlation measures, such as Pearson and Spearman. However, the way the paper implements it seems to make percentage changes in housing prices a function of inverse distance. This doesn’t seem appropriate since variation correlated to the percentage change in housing prices usually exists exogenously, not at the spatial level. Anyway, I went way too deep into that. Here’s an image showing the clusters of housing prices over the years.
