Chapter 1-4 Final: Survey
Chapter 5-7 Final: Animation WebApp
week 5
Chapter 7 was all about understanding the basic terminology of web scenes they give us opportunity to create web scenes using the same viewer. It was understanding the value and configuring 3-D maps. The two types of 3-D scenes we learned about were photorealistic and cartographic. The photo realistic were used to create features and cartographic used to do thematic mapping to display features. I learned as there is a lot of ways to represent 3-D images and data.
I think i will be creating a app off of the information from chapter 7 for my second app.
smith week 4
Chapter 6, demonstrates how screens can be used in real time. Chapter 6 divided spatiotemporal data Into four main types: change, stationary fixed, and moving each give you the ability to view different patterns and trends. I thought it was very interesting and will be extremely useful for the real-time data to be broadcasted to agencies like emergency response or environmentals or just companies that need real time feedback
Henderson Week 5
Chapter 7 was about web scenes. It first introduced the basics of 3d maps and web scenes and then explained how to navigate them and symbolize them properly. The first tutorial was just about navigating web scenes using the scene viewer. The second tutorial taught me how to create a thematic web scene. I created a local scene and then added layers from ArcGIS Online. I then learned how to change what attribute to visualize and that there are different ways to symbolize those attributes (both 2d and 3d). I then could change the color and range of the histogram. There were many different ways to style the layer to make it fit what this scene was meant to be used for. The third tutorial had me add two different layers and symbolize all of the different points. I had trouble with this tutorial at first; nothing was showing up until I opened it on a different browser but after that it was quite easy. 7.4 was about adding new features that could be moved along the z axis (above or below ground). I was able to put helicopters in the sky and also add buildings to the scene. 7.5 was about editing features in the web scene. I was able to add cars to the scene and learn how to change the size and direction they were facing. In the last tutorial I learned how to do basic analysis in a web scene. I was able to add shadows based on the day and time and watch the shadows change as the day progressed.
If I were to do an assignment from this chapter, I would create a web scene of campus and add different features to represent different areas of campus, e.g., cars for parking lots. I think it could be cool to create a web scene based on a place I have been because I could make it realistic and almost like a campus directory.

Getting to Know Web GIS (2022, 5th edition)
Chapter 7
Photorealistic (recreates reality using photos to texture features) and cartographic (moves 2D thematic mapping techniques into 3D) are the two main types of scenes, or 3D web maps.
The 4 main elements of scenes are surfaces, features, textures, and atmospheric effects.
The Main Types of Scene Layers (3D Layers):
3D Object Scene Layers – Used to represent and visualize 3D objects.
Building Scene Layers – Allow the user to visualize complex digital models of buildings and interact with all the components of a building.
Integrated Mesh Scene Layers – Constructed using Drone2Map, which is a desktop app that turns raw, still imagery from drones into valuable information products.
Point Cloud Scene Layers – Provide a fast display of large volumes of symbolized point cloud data.
Point Scene Layers – Used to display large amounts of point data not possible with a point feature layer.
Voxel Scene Layers – Represents multidimensional spatial and temporal information in a 3D volumetric visualization.
The General Steps to Creating Web Scenes:
1. Choose a global or local scene
2. Choose a basemap
3. Add layers
4. Configure layers (layer styles, labels, pop-ups)
5. Capture slides (if needed)
6. Save and share
VR uses headsets or multiprojected environments to generate 3D views, sounds, and other sensations that simulate a user’s physical presence in a virtual environment. XR refers to all real-and-virtual combined environments and human-machine interactions (AR, VR, and MR). A metaverse is a network of 3D visual worlds focused on social connection.
ArcGIS Urban applies GIS technology to urban planning to streamline plan creation, analyze the impact of plans, visualize current projects, and facilitate public engagement.
Chapter 7 – Web Scene Using Feature Layers and 3D Object Symbols (Carpocalypse)
Application based on ideas from Chapter 7
I could create a 3D web scene that shows where light pollution might be highest in Delaware County, helping identify areas where wildlife or human health could be impacted. Using land use and building footprint data, I would upload these layers to ArcGIS Online and build the scene in Scene Viewer. I would then extrude the buildings to visualize densely built-up areas and use smart mapping to color-code land use types, highlighting commercial and industrial zones that typically contribute more to light pollution. I would also add a layer for parks or open spaces to show which natural areas are most affected by nearby development.
Cooper Week 5
Chapter 7
The flow chart on page 230 was very helpful in understanding which platforms do what for which types of jobs that need to be done. I learned about the two main types of web scenes, which are photorealistic (which aim to recreate photos and textures); this type of web scene would be used to recreate surroundings. I also learned about cartographic web scenes (which are used to take 2D data and make it 3D by extruding values). VR was not something that I really thought of before when thinking about GIS and applications, however, it makes a lot of sense. The Venn diagram on page 241 was helpful in understanding where VR, MR, and AR lie as an XR and their scale between presence and immersive. The indoor GIS was also very cool to think about in terms of VR and other game-based applications. A potential application from this chapter would be using Delaware data to create a cartographic web scene of land ownership within the county to show which areas have the most ownership for potential tax reasons.
Flores Week 3
I really like learning how to make applications and websites. It is actually really helpful for my classes because it brings in this new idea that I can make a website or GIS application for a class project. It’s really cool that we get to learn how to create a web experience with all these add-ons you would think are really difficult when in reality it’s super easy with just a click of a button. Experience Builder is a really nice website because it gives you an already made layout which you can use, and just add your own information or data to make a web experience. In chapter 4 we learned about mobile ArcGIS and how easy it is to use these complicated sounding apps on your mobile device. These apps were really interesting to learn about because of its use of VR, and its ability to locate things inside and its rapid data collection. In this application we could compare 2D and 3D areas of Delaware, you could compare the Tax districts and zip codes, and see the connections.
Tomlin Week 4
Chapter 4:
This chapter emphasized the increasing mobility and accessibility of GIS across various devices. I found it interesting that Web GIS isn’t limited to smartphones and tablets—it’s even being integrated into wearables. It made me realize just how embedded GIS is becoming in our everyday technology.
Chapter 6
This chapter introduced the concept of spatiotemporal data—information that’s tied to both time and location. This idea is central to real-time GIS applications, and the chapter effectively demonstrated how it’s used in real-world scenarios. Examples like emergency response, environmental monitoring, and traffic tracking helped me better understand how these systems function in practice, beyond just theoretical concepts.
One part that really stood out was the discussion on the Internet of Things. While I’ve come across the term before, this was the first time I truly understood how the Internet of Things connects with GIS. Seeing how real-time data is gathered and processed using tools like GeoEvent Server and ArcGIS Velocity made the concept much clearer. These technologies automate the collection and analysis of sensor data, opening up powerful possibilities for live monitoring and informed decision-making.
Learning about ArcGIS dashboards was also a good experience. They seem incredibly effective for visualizing complex spatial data in a clear, user-friendly way. I also appreciated the deeper look into time-enabled layers and how they can be used to animate changes over time.
Tomlin Week 3
Chapter 3:
This chapter was fairly straightforward. I like that this assignment allowed us to create something we can actually publish.
Chapter 4:
I found this chapter engaging because we got to develop a new skill.. It was also interesting to see how GIS continues to evolve alongside the growing use of mobile devices. I often use Apple Maps for directions, and I realized how heavily our daily lives rely on GIS technology. Although the mobile app tutorials were very in-depth, it was definitely helpful to take a deeper dive into what the Esri apps could do.
Application:
The Survey123 tool has a wide range of potential uses. One practical application could be tracking invasive species of bugs, plants, or other animals. With its variety of input options—including multiple-choice questions, map locations, file uploads, and email fields—it would make collecting data more efficient. Residents in Delaware County could report where the species is found, estimate the amount, indicate whether removal was attempted, and provide other useful details. This could help encourage community involvement and make managing and eliminating invasive species more effective.
Plunkett Week 4
Chapter 6
This week’s chapter focused on spatiotemporal data and real-time GIS. I’ve heard about IoT, but wasn’t sure of its definition, so I made sure to look it up (it gave the definition later). I’ve never considered how many sensors are used in everyday life, such as how smart cars use sensors and GIS data to calculate routes and recognize road conditions. The ArcGIS dashboard seemed really useful with being able to use real time data to track crimes, environmental conditions, and social media.
Application Idea
I would create a dashboard showing real time air quality across the map. The dashboard would use data from air quality sensors from around the state. It would track various pollutants and have visual alerts for bad air quality and its location. I would also animate the data so that you could visualize the patterns and trends of the air quality.
