Month: April 2025

In lieu of recent events with the library, I chose to make a survey on where students like to study. Having the library freshman year was quintessential to my education, but I had to quickly adapt. With the class, I was curious where other students turned to. This is the link: https://survey123.arcgis.com/share/fd95f65f47b84959895513a4e8d39efe?portalUrl=https://owugis.maps.arcgis.com.

Secondly, I thought the camera trap data from the redlands was interesting, so I chose to make it applicable to somewhere I am a little more familiar with. Not quite my home, but close to Maryland. I think it is so interesting that the data can be updated every 5 minutes. this is the link https://owugis.maps.arcgis.com/apps/mapviewer/index.html?webmap=fe3447587d2d42208af4cf0407f4b546

Application 1: Chapter 3 – Web Experience

My first application is a web experience, or interactive map app, built using ArcGIS Experience Builder that provides users with a comprehensive view of Delaware County, Ohio, displaying important features such as parcels, streets, building outlines, hydrology, and emergency jurisdiction boundaries. Its primary purpose is to assist emergency responders, urban planners, and decision-makers in planning response routes, assessing environmental risks, and understanding jurisdictional responsibilities. By making various datasets available and easily accessible, it enhances situational awareness, allowing users to quickly analyze and access critical location-based information, which can improve response times during emergency situations. To create this web experience, I first downloaded relevant GIS data from the Delaware County GIS Hub, including layers for address points, street centerlines, parcels, building outlines, and hydrology. These datasets were then uploaded and published as hosted feature layers in ArcGIS Online. I used ArcGIS Experience Builder to construct the app, selecting a map-centric template to display the data interactively. The app includes tools such as layer toggles, feature pop-ups, and search functionality, allowing users to explore the data and make informed decisions. I configured various widgets like the Layer List and Feature Info to provide users with an intuitive, easy-to-navigate interface. This tool is now a resource for anyone needing to analyze the spatial relationships between the various data layers in Delaware County, particularly for emergency management and planning purposes.

Application 2: Chapter 6 – Dashboard

This ArcGIS Dashboard application provides an interactive visualization of school districts, voting precincts, and tax districts within Delaware County, Ohio. Its primary purpose is to help users explore how these three administrative boundaries overlap and vary across the county. By integrating multiple data layers into a single visual interface, the dashboard enables a clearer understanding of local governance structures and how jurisdictions may impact decision-making in education, elections, and taxation. Viewers can quickly see which areas fall within specific school districts or precincts and how tax districts align with those boundaries. This type of insight can be valuable for county officials, school board members, and residents interested in understanding the spatial organization of public services. After downloading geospatial data for school districts, tax districts, and precincts from Delaware County’s GIS open data portal, the layers were uploaded and styled within a web map. This map served as the foundational element for the dashboard. Within the ArcGIS Dashboards interface, the map was enhanced using interactive elements such as selectors, charts, and filter-driven visualizations. The bar chart enables side-by-side comparisons across district names or areas.

For my first application I created a survey that people living in Delaware can use to file complaints about the schools districts they reside in.

My second application I made a 3D map documenting female Covid-19 cases in Ohio

For my first application, I used an idea from Chapter 1 and I created a map tour involving my personal story. Chapter 1 Application

For my second application, I created a 3D map with ideas from chapter 7. This map shows female population in the United States by county with purple meaning there are more females in the county and they appear higher on the map. Chapter 7 Application

I already completed the Delaware Data Inventory in a previous weekly posting, but here is the link to that posting again.

Have a good summer, everyone!

In chapter 7 we covered 3D in GIS applications. 3D would be an interesting topic to explore, maps are mostly 2D but we live in a 3 dimensional world, so it would make sense to develop maps in the world we recognize in order to get a better visualization in storytelling, map planning, and architectural design. Learning about the feature layers was so cool, it reminded me of GIS 291 during the final chapters where we could add 3D trees and things to our map to give it more dimension and recognize how the map is visualized, it was really fun being able to relearn some of that. 

Application idea: something we could use 3D techniques for in Delaware is viewing population density and how populated town is, where it could be more or less populated in order to build more housing, or protect wildlife and not build where it is unnecessary because of the lack of population in that area.

Spatiotemporal data are data that is collected across both pace and time. It can be collected through observational sensors or simulation models. This can be shown in GIS through live observations that are currently changing and updating. Things like social media, weather events can all be tracked with spatiotemporal data. loT is the network of physical objects that use different data and exchange and collect it. I liked that we were able to connect the different first responders into a web app so they could all coordinate, it really helped me grasp the concept of how GIS uses real time locations and incidents. 

Application idea: Something you could use an application for with spatiotemporal data is changing addresses, people are moving in and out of homes in Delaware, we could be able to track how often people move in and out to create a pattern to potentially improve a neighborhood to increase retention in a neighborhood. Using loT we can collect and exchange the data to create a more connected system. We can view how close parks are, the proximity of a nearby city, public parking and proximity to grocery stores and other shops.

(I thought this was posted already but it never did so I am rewriting it now)

Chapter 1:

This chapter had similarities to what I did in Geog 291, but was different since it is applied to ArcOnline. I started strong but quickly got confused when trying to upload the Redlands data. As I continued, I was able to familiarize myself with each of the tools and discovered there is a lot you can do. I think this chapter was well explained, but lacked some necessary pictures, I felt I needed to better understand what I was doing. As I navigated through 1.4 I ran into another issue, I was unable to complete step 11. I could not find the “select layer field of sort by”; anytime I clicked where it would be, it disappeared. I reviewed other students’ maps in our organization to see what they looked like since mine did not end up looking as it should.

Chapter 2:

For chapter 2 it focused on Smart mapping and storytelling with GIS. The first tutorial was to create a feature layer using geocoding. I had to download the data from the main website onto an external drive. The tutorials were relatively easy compared to the first chapter. In tutorial 2.2 I was able to stylize all of the needed arrows and colors however it didn’t look quite right. I ran into another problem in the third tutorial when trying to use expressions to calculate things. Towards the end of the chapter we created a story about US population change. I had trouble stylizing some things in the story but I believe it looks as it should. I didn’t run into very many problems in the last tutorial the chapter. Overall, the story i created conveyed the proper message asked by the book.

Application:

An application could be made about the population change in Delaware. I’ve heard from many people that Delaware has quickly became a very populated area in a short amount of time. I could create a story map showing how many people have moved here within the last ten years and where they chose to within the city.

Chapter 6 Spatiotemporal data and real-time GIS

This chapter introduces the concept of spatiotemporal data and the values and challenges of the Internet of Things (IoT) in relation to ArcGIS. Spatiotemporal data can be categorized into groups: Moving (live feeds of airplanes, buses cars etc.) Discrete (criminal incident, earthquakes), Stationary (wind speed and direction measurements at weather stations) and CHange(perimeters of wildfires, flooded areas). In spatiotemporal GIS data, the time value of an event can be a point in time or a duration of time. 

Application:

I was really interested in the idea of spatiotemporal data because this chapter was my first time hearing about it. When looking at the Delaware data from GIS 291, I think a good application would be one that is similar to my final from GIS 291, creating a spatiotemporal application that maps emergency incidents. By using available data, the application would display real time emergency incidents as moving or discrete events on a web map. This would include filters by incident type, time of day or severity. It would animate changes over time to identify got spots or trends in emergency services. This application could be deployed as a web app using ArcGIS Enterprise.

Chapter 3 

This chapter introduces Experience Builder and shows us the basics such as templates, themes, widgets, pages, windows, layouts, ect. It also talks about using Experience Builder to create web experiences. A widget is a JavaScript and HTML component that encapsulates a set of focused functions. Experience Builder provides basic and layout widgets. Tutorial 3:1 is about using Experience Builder to create a web app. It was interesting to learn how to create a simple ‘web experience’. I got a little stuck on tutorial 3:3, I could not find the statistics tab in the dynamic content window,  so I moved on to 3:4.  I was unable to complete 3:4. The beginning of the tutorial had me drag the table widget onto the page and then in the settings pane click ‘new sheet’. However, there was no “new sheet” button in the contents pane so I could not finish it. 

Chapter 4- mobile GIS

This chapter first starts off with an overview of mobile GIS.  There are lots of advantages to mobile GIS but because of the size of mobile devices, CPU speed, memory size, battery power, bandwidth and network are all limited.  The first tutorial is Design a survey for ArcGIS Survey 123. It was just making a survey. It was easy, except in step 13 it said to “click the Incident Type question, and click Set Rule icon”, which was impossible to do because there was no Rule icon where the book said it was going to be nor anywhere else I looked. This did not ruin the rest of the tutorial for me though. The next step was to download an app on my phone for the survey I just created. 4:3 was fine, but there was no “change style” button underneath the layer name that I could see, so I could not do that section. 

Chapter 1- get started with Web GIS
This chapter introduces the fundamentals of web GIS, outlining its benefits and key components. The basic components of a web GIS app are the base maps, operational layers, and tools. The chapter also emphasizes the power of web GIS to provide real-time data and accessibility across various devices and groups of people. It explains how cloud computing, web services, and APIs facilitate data sharing and integration. The first tutorial was easy once I got going. One of the first things I had to do was make a web map made from data downloaded from the ArcGIS website. Then we had to create an instant web app using a template.

Chapter 2 – smart mapping and storytelling with GIS
This chapter continues discussing feature layers and web apps by first introducing feature layers and the different ways to style them using smart mapping. The tutorials for chapter two were also very straightforward and easy. The first one was just editing names from data imported from Microsoft excel. I got a little stuck on 2:2. When making the style for the map of the top 50 US states, the data for 2020 and 2010 was switched (the directions were to style the Census 2020 data with the theme “above and below” but there was no option for the 2020 data) . 2:3 had some coding, but it was easy to follow.
