Chapters 1-4 App:

https://owugis.maps.arcgis.com/apps/instant/attachmentviewer/index.html?appid=1df466deebe8476e86a28f4c0d4ace68

For my first app, I decided to create my idea for Chapter 1. It is very similar to the Redlands Attractions Map Tour, but I decided to do a tour of some of Ohio’s State Parks. First, I had to compile my data and create a CSV. I picked 5 state parks: Salt Fork and Mohican because I love to go camping there, Wingfoot because I worked there, Alum Creek because it’s so close to OWU, and Hocking Hills because the geology is so unique! After I decided on my parks I created columns for their longitude and latitude and filled them. Then, I made a column for a Description/Caption. I described each park based on the ODNR website information or on what I already knew about the park. I then embedded the link to the website. I then went to ODNR’s public Flickr account and found a picture for each park. I downloaded this CSV from Excel and uploaded it as a hosted feature layer. I then enabled attachment on the layer and added my images. Then I configured the symbology for the points and chose which fields to include in my popups. After that, I created an Instant App with the attachment viewer template. I chose to use an attachment-focused view instead of a map-focused view like we did in the exercise because it looked aesthetically better. After that, I published the app. I think this app would be really useful for people who are visiting the state or just looking for parks to visit!

Chapter 6-8 App:

https://owugis.maps.arcgis.com/apps/instant/slider/index.html?appid=333c829c01d04c5889cd37dacec4c463

I made this app based on the content in Chapter 6. My original idea was to do a time series on freshwater usage around the world over time. However, the time field was not working on that data, so after trying to clean and modify it I decided to just find a different dataset. This one was for a Store in the United States and it tracked their sales and where people ordered from overtime. So, I created a hosted feature layer and then configured my map. I symbolized each sale with a shopping bag and set the attributes I wanted to display in the popups. If you click on a sale it will now show things like who’s order it is, the price, the location, what they ordered, when they ordered, and shipping information. I then made sure the Time Settings were enabled for my layer. After this, I created an Instant App with the Slider Template. I customized the color of the time slider to match my sale icon and I added the legend to the map. Then, I was finished and published the app! I think this would be really useful for employees at all levels of this business to see what type of products are selling, where they are selling to, when they are selling, and for packaging and shipping items.

Here is the link to the store data I used: https://www.kaggle.com/datasets/blurredmachine/superstore-time-series-dataset/

Chapter 7 Comments, Notes, Questions

1. The basic form of 3D GIS is 3D web scenes and scenes (these can have multiple layers)
   1. Layers: feature layers, map image layers, raster/vector tile layers, scene layers
   2. There are two types of scenes: (1) Photorealistic (recreates reality using photos to texture features) and (2) Cartographic (takes 2D thematic mapping techniques and applies them to 3D mapping)
   3. Displays: (1) Local (on a planar surface) and (2) Global (spherical surface)
2. Main elements in scenes
   1. Surfaces: continuous measurements with x and y values for location
      1. DTM (digital terrain model), DEM (digital elevation model), and DSM (digital surface model)
   2. Features: live on, above, or below surfaces (operational layers)
   3. Textures: exterior or covers of your 3D feature
   4. Atmospheric Effects: for example, lighting or fog
3. Web Scenes and Web Scene Layers
   1. 3D Object Scene Layers – represent and visualize 3D objects (can be created manually or automatically – procedural modeling)
   2. Building Scene Layers – visualize complex digital models of buildings and interact with their elements
      1. Structure: Overview, Discipline, Category, and Filter
   3. Integrated Mesh Scene Layers: turn raw drone imagery into valuable information and layers
   4. Point Cloud Scene Layers: display large volumes of symbolized point cloud data (usually collected from lidar or generated from Drone2Map)
   5. Point Scene Layers: display large amounts of point data not possible within a point feature layer
   6. Voxel Scene Layers: for multidimensional space and temporal data
4. VR, XR, and the Metaverse
   1. VR: available through ArcGIS 360 VR and 3VR
   2. XR: real and virtual combined elements (inc. AR and MR)
   3. Metaverse: a network of 3D virtual worlds focused on social connections (includes real metaverses for working)
5. Indoor 3D GIS
   1. Challenges: GPS doesn’t work well indoors, and space is often in complex 3D formats
   2. ArcIndoor components: ArcGIS Indoors for ArcGIS Pro, ArcGIS Indoors Viewer, Indoor Space Planner, ArcGIS Indoors for iOS and Andriod
6. ArcGIS Urban
   1. Applies GIS technology to urban planning
   2. Main content types: plans, projects, indicators, and ideas
7. ArcGIS GeoBIM
   1. ETL: requires ongoing maintenance, which is costly and difficult to scale
   2. BIM as 3D graphics: good quality visualizations, but eliminates BIM attribution, metadata, and georeferencing info
   3. ArcGIS GeoBIM: bridges the gap between GIS and BIM
      1. Provides organization and simple, streamlined communication between the 2.

Chapter 7 Application: For this application, I think I would like to make my own Fun Park. My favorite park from back home has walking trails, a lake, a marina, a library, a wildlife center, and lots of playgrounds, benches, and tables so, I think it would be fun to visualize it since there are so many different attributes and symbols I could customize. I’m also pretty sure they have a public GIS hub where I could get some type of point layer or map of the features to get me started, so I think it’s doable!

Chapter 6 Notes, Comments, and Questions:

1. Spatiotemporal data includes observations of events, objects, etc. that move and change through time. This data has 4 categories:
   1. Moving, Discrete (something happens at a time/place), Stationary (still, but values change), and Change (growth)
   2. Time values can be a point in time or a duration of time
2. IoT: a network of physical objects embedded with sensors and are network connected to enable these objects to collect/exchange data
   1. Smart cities: uses IoT to supply info that will assist in managing the city assets and resources better (and smart homes)
3. Velocity and GeoEvent Server
   1. Ingest: compatible with many sources and forms of data (Communication component)
   2. Process: Processes the data received from the ingest component. It can provide filters and real-time analysis.
   3. Output: Send the processed data to a variety of destinations
   4. Velocity items: feed items (sensor input receiver), real-time analytics, big data analytics
   5. Delivery (server to client): Polls (ex: retrieves data every 30 seconds) or Push (serve data in real-time)
4. Dashboards: common view of systems and resources you manage
   1. Arcade in dashboards: expression can be used as a data source and used to control control over the looks of a dashboard
5. Mission: real-time communications and situational awareness product that helps with the coordination of movement and communication among an organization.
   1. Manager (web app, organizes missions), Responder (communication), Server (links manager and responder)
6. Animating Time Series Data
   1. Time series: a sequence of data points captured over intervals of time
   2. Animating data lets you visualize it at each interval
   3. To do this you can use a time-enabled web layer, add it to a web map, and create an app from the web map

Chapter 6 Application: 

• My idea for an application for this chapter is an animated time series on how freshwater usage has changed over time. The data (CSV) I have is from Our World in Data and it tracks freshwater usage around the world from 1962 to 2019. I believe this would fall in the change category for spatiotemporal data because it shows how usage changes over time. I would create a time series map and I would also like to try to include a dashboard  to visualize some different charts, lists, and statistics with the map if I feel it is appropriate for this data

Chapter 3 Notes, Comments, and Questions:

1. What can experience builder do?
   1. HTML and Java scripts without programming
   2. Out-of-the-box widgets (can be used, remixed, and configured)
   3. 2D and 3D web apps work across many platforms
   4. Different flexible layouts
   5. Widgets respond to other widgets
2. How do you use it?: Workflow
   1. Template, select theme, select source data, configure widgets, refine layouts, save, preview, publish, and share
3. Basic Components
   1. Page = foundation (consists of header, footer, and body)
   2. Window = complimentary to page (only has body content)
   3. Outline view that lists all widgets on page
4. Widgets
   1. Basic: functional, perform as app tools (ex: map, legend, etc.)
   2. Layout: organize widgets on your layout window (ex: section, column, row, etc)
   3. Customizable widget settings: there are 3 categories (Content, Style, and Action)
   4. 2 groups of Widgets:
      1. Message Actions: These have 3 components (triggers, targets, and action)
      2. Data Actions: These do things like exporting records to a file (for example)
5. 3 Editions of Experience Builder
   1. Embedded in ArcGIS Online
      1. This edition does not allow for custom widgets.
   2. Embedded in Portal for ArcGIS
   3. Developer edition
      1. Developer Edition has the greatest extended functionality.
      2. You can create, deploy, and use custom widgets.

Chapter 4: Comments, Notes, Questions:

1. Mobile GIS (concepts and advantages):
   1. Mobility
   2. Location Awareness (GPS, Cellular, WiFi, Bluetooth, etc.)
   3. Ease of Data Collection
   4. Near Real-Time Info (Spatial and Temporal Data)
   5. Large Volume of Users (More Accessible)
2. Mobile GIS Devices/Usage
   1. Smartphones, Tablets, Watches, etc.
   2. Mobile OS (Andriod, iOS, Windows)
   3. Wireless Communication Technology
   4. Positioning Technology (Satellite, Network-Based, etc)
3. Trade-off: Mobile devices are less powerful, slower, and have less memory and battery, but are more portable and accessible.
4. Feature Layer Views
   1. You can create a hosted layer that mirrors/references your original layer so users can edit and the public will automatically see those changes 
   2. Survey123 will automatically create these behind-the-scenes views
5. Feature Templates: defines types of data items that users can add to a layer
   1. Data Integrity: prevents users from entering invalid values
   2. Ease of Editing: presents make it easier to know what type of data you are using
6. Mobile App Development Strategies
   1. Browser-based: less costly, quicker, can only access a limited amount of device features
   2. Native-based: apps you download and install, deep-level access, faster, more expensive, can’t run on multiple platforms
   3. Hybrid-based: combo of native and browser-based
7. ArcGIS Native Apps 
   1. Field Maps (Mapcentric)
      1. Plan and coordinate fieldwork, owner can configure projects and attachment types, dispatchers create/prioritize assignments and send out deadline reminders, mobile workers use the app to process and do work
      2. You can also track and capture the locations of mobile users
   2. Survey123 (Formcentric)
      1. Smart Survey w/ dropdowns
      2. Store results in hosted feature layer (online and offline data collection)
      3. 2 ways to design smart forms:
         1. Web Designer: quick, simple, not all smart features available
         2. Connect: more advanced questions and features, desktop app, can pull from outside data sources
   3. Quick Capture
      1. Made to capture data from a moving vehicle
      2. Send/update data in real-time
      3. Very minimalistic interface
   4. Indoors Mobile App: indoor mapping for things that are going on with/in your organization’s indoor environment
   5. Companion
      1. App to access your ArcGIS organization, content, and profile
      2. Perform administrative tasks and search/browse content on the go
8. VR, AR, and other frontiers
   1. LBS: offered through mobile devices (considers location in use). 
   2. VGI: spatial data produced voluntarily by citizens
      1. Survey123 is best for this type of data collection (doesn’t require an account)
   3. VR: simulation of 3D Map/Environment (replaces reality)
   4. AR: an enhanced version of reality (overlay reality)
      1. Tabletop and World Scale ArcGIS toolkits can help implement AR

Chapter 3 and 4 Application: 

1. For an application for Chapter 3, I would use Experience Builder I would create an app that centers on mineral resources throughout the world. I would create a map of these primary mineral resources and possibly one for the secondary resources or compound type for these places as well. I would add a chart widget that you could configure to show how much of each ore was present in certain regions, a list widget of regions and their resources the user could sort, and another page with common uses for the resources. 
2. For the application for Chapter 4, I was thinking of creating a smart survey in Survey123 to be used around Campus. I could be used to report things that need maintenance to buildings and grounds. You could submit photos of the broken thing, provide contact info, specify what type of maintenance needs to be done, etc.
