Geography 292: Geospatial Analysis with Web GIS

My name is Camryn Henderson and I am a freshman from Wadsworth, OH. I am an ENVS and Theater double major with a PG minor. I took GEOG 291 in the first half of the semester and am excited to expand my GIS knowledge.

In 291 I looked a little bit into my ArcGIS online account but I looked more in depth this week. One interesting thing I found was the different categories in the Training section. There are numerous different programs to help familiarize you with ArcGIS which I think will be very helpful for the rest of the semester. The other interesting thing was the ArcGIS blog which has many articles discussing updates and different things you can do with ArcGIS.

One really cool thing I learned from the Introduction page was all of the different ways you can share your work. You can create notebooks, and web apps, and collaborate with other users to make something together. The other cool thing is that once you are a member of ArcGIS online you are able to communicate with other members and all of your work will be saved in a cloud.

During the course one thing I had not known about was what all of the different app builders that you can use. I was able to learn how to use Instant App which allowed me to quickly make my map an interactive web map. Another interesting thing I learned in the course was about the different levels of sharing you can have for a map. Private, Group, Organization and Public all provide different levels of privacy for a map and are used for different things.

Two courses I find interesting were “Collect Data in the Field using ArcGIS apps” and “ArcGIS Online Fundamentals”

The first map I found was about the migration patterns of Great White Sharks off the coast of Australia. They tracked sharks using GPS and the heat map technique to show where most Great Whites tend to reside during their migration period.

The second map was about criminal activity (specifically burglary) in a county in Florida. The yellows and reds indicate a higher amount of burglary than the blue areas. I found this on a website that gave a tutorial on how to best symbolize criminal activity on GIS maps.

Hello! My name is Ashley Bahrey and I am a junior Zoology, Environmental Science, and Geography major. I am from Bristolville, Ohio and I like to make jewelry and crochet in my spare time. I also have three cats that I love and adore!!!

Upon poking my OWU ArcGIS Online account, I was able to discover a lot about Esri and the resources that I can interact with. I did not expect the available training courses to have estimated completion times ranging from hours to weeks. I also found the Field Operations training curriculum category surprising, but it certainly makes sense that enhancing field data collection accuracy would improve the overall efficiency of GIS projects. I have stumbled upon the Esri Community page while troubleshooting for desktop GIS and I think it’s really cool that there is a public place where users can come together to solve problems and the records of these exchanges can be used to craft a solution to a similar issue. 

Reading through “Get Started: What Is ArcGIS Online” exposed me to loads of awesome tools I will be able to use to visualize 2D and 3D data with ArcGIS Online. I learned that the ArcGIS Notebook Editor includes a Tasks feature that allows you to schedule notebooks to run automatically, meaning ArcGIS can process data or generate reports on a set schedule without you having to run them manually. I was also introduced to Instant Apps for quickly building web apps, Web AppBuilder for more customizable apps, and Field Apps for data collection in the field, which are selected based on what you want the app to do (viewing, analyzing, or collecting geographic data).

ArcGIS Online Basics Training Course:
The ArcGIS Online Basics training course showcases the general capabilities of ArcGIS Online and provides a good summary of web layer types and functions. The scenarios for choosing the appropriate sharing level (private, group, organization, or public) at the end of section 3 demonstrated why it is important to consider who can access your organization’s content in certain scenarios. Section 4 taught me about how ArcGIS app builders allow you to create interactive web apps without coding, offering tools like Instant Apps, Dashboards, StoryMaps, and Experience Builder to enhance your content and engage your audience.

Two Esri online training courses that look interesting to me are “Getting Started with Data Management” and “Using GIS to Solve Problems”. I believe that learning how GIS data is structured, stored, and accessed as well as a five-step process to solve a problem using GIS would better equip me with the skills to utilize GIS efficiently in the future.

Search 1: “ArcOnline atrazine”

This map is found in a StoryMap made in ArcGIS Online which recaps a 2021 study led by Atreyi Guin, graduate student at the University of Michigan, that identified the stream networks vulnerable to pesticide (atrazine) contamination within the North Raccoon River Watershed in northern Iowa using the weighted overlay method in ArcGIS Pro. 55% of streams fall under the risk of being contaminated with pesticides from the adjacent corn fields and of those “at risk” streams, nearly 19% are in close proximity to highly populated areas with a population of more than 10,000 people.

Search 2: “ArcOnline superfund sites Ohio”

This is a map of Superfund reuse sites, or formerly contaminated Superfund sites that have since been remediated and are being repurposed for new, safe, and productive uses (green space, commercial, residential, public service, industrial, military/federal use, or mixed use projects) in Ohio. Data points were obtained from the Superfund Enterprise Management Systems (SEMS) database and the map is updated as more sites are placed into reuse (last updated on October 8th, 2024).

Real-time GIS and spatiotemporal data are used to track and visualize changes over time and space. The types of data this explored are moving data (like moving objects), discrete data (specific events like weather), stationary data (fixed objects with changing aspects), change data (shifts over time). This allows us to look at trends from the past or real time data. A few of the things included in the tutorial were the living atlas, dashboard creation, arcade scripting, data categorization, time series data, and population changes. I found these tutorials interesting and applications could be interesting too. One thing I thought of is that I mobile ordered at starbucks last week and the line was super long so the drink wasn’t ready when it said it was. An application of this could be real time data about how many orders they are working on or how many people are waiting.

ArcGIS Experience Builder and Mobile GIS are powerful tools for creating and interacting with geospatial content across platforms. Experience Builder enables users to design customizable, mobile-friendly web experiences with drag-and-drop and widgets for 2D and 3D data. It integrates with ArcGIS Online, ArcGIS Enterprise, and the ArcGIS API for JavaScript. Mobile GIS extends GIS capabilities to portable devices like smartphones and tablets, enabling realtime data access, updates, and fieldwork through apps like ArcGIS Field Maps, though smaller screens can limit detail. I thought Chapters 3 and 4 were a little bit more difficult, but also not as interesting as the previous ones. I ran into a few issues, but moved past them fairly easily. There could be several different applications for the features in these chapters because interactive tools like surveys can genuinely be used in any field and make things get mapped more easily.

App 1: Places to See in Montréal

https://owugis.maps.arcgis.com/apps/instant/attachmentviewer/index.html?appid=f4181d6cea2546eda6533bef7a3de982

The first app I made for my final project reflects the topics covered in the Getting to Know Web GIS chapters 1-4. I particularly enjoyed using the Instant Apps program to make a detailed app showing points of interest, such as the one completed in the chapter 1 tutorial. Places to See in Montréal uses the same Instant App format as the one in the tutorial, but with this app I wanted to incorporate points of interest that I saw or visited during a trip with my parents in 2023. To create the app, I first started by making a .csv file with Google sheets; In it, I included the name of the point of interest, a short paragraph to caption the location, and the location’s longitude and latitude. Following this, I then loaded the .csv file into ArcOnline as a Feature Layer, which I opened in Map Viewer to edit basemap, symbology, and visible fields to ones that were cleaner and more cohesive. Once this was complete, I loaded the map into an Instant App preset, and finalized the project. The result is an interactive map displaying 10 pinned locations, each with a caption and 2-3 relevant images attached.

 

App 2: Hocking Hills Hiking Guide

https://owugis.maps.arcgis.com/apps/dashboards/27e9fc7199cb463f98f874c5f1d7de81

The second app I made for my final project reflects the topics covered in the textbook chapters 5-8. I took inspiration from the chapter 6 dashboard tutorial and made my own dashboard for people interested in hiking in Hocking Hills State Park. The dashboard was designed to provide information for hikers about the status of trails, weather conditions, and other helpful landmarks like parking lots and trail waypoints to ensure a safe and well-planned excursion. I started this project by using the ODNR’s Hocking Hills map for the location of trails and points of interest. After hiding the nonessential information, refining the pop-up details, and changing the symbology, I added the map to a new dashboard. I turned on features such as a search bar and location finder to help hikers navigate to a specific point of the park or their own location. Afterwards, I added in a map of weather advisories from the National Weather Service that automatically refreshes. I finished up the project by adding legends, titles and subtitles, and a theme to make the dashboard clean, legible, and effective.

For my first app I made a survey with survey123 to help locate and collect data to help fill out a life list. A life list is quite literally just a list of birds you have seen in your life so this is kind of a cool way to help collect that data. It is a 4 question survey that collects data for: which bird it is, what the date and time where when observed, where the bird was spotted, and an image of the bird if available.

Application 1: https://arcg.is/KrCDz

For my second app I have a map that updates in real time as the survey is filled out. The survey data is imported and overlayed onto the base map and is indicated by red diamonds to help stand out from the background. While the data is added to the map it is also input into a histogram to help show the most popular time of day that birds are active.

Application 2: https://owugis.maps.arcgis.com/home/item.html?id=4ea82ae450ef4e498090ed57dab06c3f#overview

Application 1 –  I created a Survey123 application to facilitate the documentation of invasive spotted lanternflies within Delaware county.  The application allows users to provide their location, a picture, a description of the sighting, their name and email address. The default range of the location feature has been set to contain the entirety of Delaware county. It is set to take the location of the device as a starting point. The location, photo, name, email, and date & time fields are all required while the description is not. It caches the name and email fields.

Application 2 – I created a dashboard for the results of my survey. Its definitely properly documenting spotted lanternflies and nothing else. I would have gotten this all done on monday but I couldn’t find the variable names I needed to use to format all the elements of the dashboard.

App 1: 3D Storymap on Locations to Visit in Seattle
This is a quick storymap showing off some of the best places to tour the city. I researched and found the coordinates for each location in Seattle that I wanted to show off, I compiled them in a spreadsheet and imported it into ArcGIS Online, where I made slides that I put into the storymap you see before you. I decided to use OpenStreetMap as the basemap because I think it was the most aesthetically pleasing 3D representation of the area. I also adjusted the time and made each point have a large 3D Cone icon.

App 2: ANOTHER 3d Storymap on Locations to Visit, this time surrounding Seattle
I love going on hikes and the nature around the Emerald City is in a league of its own so I decided it warranted its own storymap. I followed a similar process to making my Seattle storymap, but I used an imagery basemap to provide a realistic aerial view of the terrain and chose trailheads around the area as the focal points. I carefully selected some of the best hiking spots that offer breathtaking views, unique ecosystems, and memorable experiences. Additionally, I used the sidecar feature in the ArcGIS Online StoryMap builder, which allowed me to incorporate smooth transitions between each point of interest.
