Rose- Week 3

Chapter 3 Notes:

  • ArcGIS Experience Builder provides more functions, larger variety of user interfaces, allows more flexible configuration of functions and user interface, and is customizable and extensible.
  • Basics of ArcGIS Experience Builder
    • Web client for ArcGIS Online and ArcGIS Enterprise 
    • Provides configurable widgets and themes
    • Creates pure HTML and JavaScript apps without coding
    • Provides framework for developers to create custom widgets and themes
  • Provides many widgets that can be flexibly combined and configured to create web apps
  • A web experience contain at least on page and can have multiple pages or windows
  • Experience Builder provides two types of actions to widgets
    • Message actions listen to triggers and perform actions automatically
    • Data action provide Actions button that end users can click in widgets at runtime and select from list of actions to perform

Chapter 4 Notes:

  • Mobile GIS is becoming the pervasive client for Web GIS
  • Mobile apps can be developed in browser, native, and hybrid-based approaches
  • ArcGIS provides a suite of mobile apps, including ArcGIS Survey123 and Field Maps
    • Survey123 is form centric and requires a form that can created using Survey123 Connect or web designer
    • Field maps is map centric for viewing maps, data collection, tacking, and coordination. For data collection, it requires an editable feature in a web map
  • Mobile GIS is the foundation of many apps and frontiers, including location-based services, volunteered geographic information, virtual reality, and augmented reality

Creating apps based on these sections would be primarily used in the field. I am not really sure what type of app I would develop. It would have to be something involving landmarks in my surroundings so I was thinking possibly an app for hiking or camping trails to keep track of where you are by identifying landmarks on the trail to avoid getting lost or just learning in general but I assume there is something already like that out there.

Rose- Week 2

Chapter 1 Notes:

  • Web GIS offers an insane amount of value when it comes to the field. It offers advantages such as its global reach, large, number of users, low cost per user, better cross-platform capabilities, how easy it is to use, and how easy it is to maintain. 
  • Web GIS awareness is growing more prominent in many organizations due to its benefits. These include, government organizations, businesses, science research, and even daily life in general. 
  • Web GIS elements include users, groups, content items, and metadata. 
  • Web GIS has five main types of content: data, layers, tools, web maps and scenes, and apps.

Chapter 2 Notes:

  • Types of hosted layers to the Esri geospatial cloud: hosted feature layers, hosted web feature service layers, hosted tile layers, hosted web map tile service layers, hosted scene layers, hosted image layers, hosted map image layers.
  • Smart mapping enables users to visually analyze, create, and share high quality maps easily and quickly with minimal software skills.
  • Pop-up windows show geographic information and deliver geographic insight. Pop-ups are a common tool that users rely on to interact with operational layers.
  • ArcGIS arcade is portable, lightweight, and secure expression language written for use in ArcGIS to style, label, and add values to layer pop-ups.
  • ArcGIS Living Atla content categories: basemaps, imagery, boundaries, people, infrastructure, environment

In an I application I would create would be comparing the food security or lack there of in different counties in Ohio. As an HHK major I study our food system and how we can improve it. By gathering data of food security and hunger through out counties and towns we can look at it through a compare A to B type of smart mapping to see trending in towns and counties and figure out why this is happening.

Rose- Week 1

Hello everyone, my name is Evan Rose. I am a very late addition to this class and will be catching up as I go so that’s why you have never seen my posts before and the reason why I am at week 1. I am a Health and Human Kinetics General major and I have never used this program before as I was not in GEOG 291 last module. 

 

Spend a few minutes poking around your account, including the icon in the upper-right corner, which takes you to your profile. Add your basic information to My Profile. Also, look at My Settings, My ESRI, Training, Community and Forums, ArcGIS Blog, and Help. Jot down two comments about what you find (for the blog entry for this Lab).

  • I did not find anything interesting in the MyProfile, MySettings, or MyESRI. Just normal basic and boring things on those pages.
  • I found the Training, Community and Forums, and ArcGIS Blog interesting as there is so much to do on this program and this is reflected on the myriad amount of training, forum posts, and blog posts on these pages.

Use some ESRI resources to learn a bit about ArcGIS Online. Complete a read-through of Get Started: What Is ArcGIS Online. This should take about 30 minutes. Read through the different sections of this web page (stacked along the left of the page) and jot down two comments about what you find (for the blog entry for this Lab).

  • ArcGIS is a very vast program that lets the user explore and visualize 2D and 3D data. This comes in the form of maps, scenes, apps, and notebooks. Through this users can share and even collaborate with others based on their own work and research.
  • I find it very interesting that when creating an app on ArcGIS it can either be hosted by ArcGIS, reside on your organization’s servers, or even use a third party resource such as Amazon to publish the application. 

Web Course: ArcGIS Online Basics

  • Web apps allow users how to interact with web maps and scenes. They provide a more focused experience with more potential for context and utility. Users can create these apps even if they have no programming experience which is good because I don’t!
  • Through these maps and apps, you can view very nuanced spatial concepts from certain landscapes and can either view and collect data privately or share with others.

Use Google and Google Scholar to look into a few GIS application areas: search for “ArcOnline” and different keywords, based on your personal interest: cat telemetry, queer online mapping, blind dung beetles, antifa, cop killings, stamp collectors, crowdsourcing, etc.). Include, in the blog posting, information on two applications with at least one map or image and a source or two.

  • One thing I like to study and look into is food security or lack there of around the United States. When looking for ArcOnline applications involving this I found that it was used to map out areas of food insecurity and different landmarks that could lead to this.

  • Another thing I looked at was the rates of obesity. ArcGIS was used in a study to mark hot spots and areas that are at risk for childhood obesity in Portugal. From this data they are able to come up with ways to combat this risk and increase the health of others in these areas.

McFarland Week 4

Chapter 6:

(Spatiotemopral data and real-time GIS)

loT = The network of physical objects, or things, embedded with sensors and network connectivity that emable these objects to collect and exchange data.

^ Think smart cities and homes

ArcGIS velocity allows use of feed items, real-time analytic items, and big data analytical items.

Poll methods = traditional approach in which a client peridocially polls the server to retrieve the latest data.

Push method = New way to serve data in near real time using the HTML5 Websocket Protocol.

Hollinger Week 4

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

Pois Week 4

Real-time GIS is used to handle objects and events that move, appear, and change through time.

  • Spatiotemporal data comes from many sources, ranging from manual data entry to data collected using observational sensors or generated from simulation models.
  • Real-time GIS refers to GIS that handles current and continuous data, which can be the latest position, altitude, speed, direction, temperature, pressure, concentration, or water level of various sensors and other objects.
  • IoT is the network of physical objects, or things, embedded with sensors and network connectivity that enable these objects to collect and exchange data.

ArcGIS Velocity introduces new types of items to ArcGIS, including feed items, real-time analytic items and big data analytic items.

The temporal nature of real-time data allows you to establish a time series or intervals of time and you can:

  • Display discrete events, such as crimes, accidents, and diseases, over time.
  • Visualize the value change at stationary objects, such as air-quality sensors and weather stations.
  • Map the progression of a wildfire, flood, land use, or environmental change over time.
  • Replay the events of an emergency, review when and how different departments responded, and learn from the past to improve emergency management and responses.

Using the information/tutorial from this chapter, I could create a display showing change over time or create a web map with real-time layers. For example, I could potentially gather data from the cameras that overlook the main jaywalk crosswalk and create a web map with real time data of it to track incidents. I’d be interested to see if this could be used to gather data about the number of cars that run red lights or fail to yield to students at other crosswalks.

Adjei Week 4

This chapter focuses on the significance of real-time GIS, especially in the context of data generated by mobile devices, sensor networks, smart cities, and the IoT. It introduces ArcGIS products like ArcGIS Velocity, ArcGIS Dashboards, and ArcGIS Mission for addressing real-time data challenges.

Key terms related to spatiotemporal data and IoT are discussed, emphasizing their role in various applications, including smart cities and smart homes.

ArcGIS Velocity, a SaaS platform on ArcGIS Online, is introduced for real-time and big data analytics. ArcGIS Dashboards provide real-time monitoring capabilities in law enforcement, environmental protection, and social media analysis.

ArcGIS Mission is a real-time geospatial communications and situational awareness product for emergency response and security operations.

Using new techniques from this chapter, I could respond to changes in the job market by collecting real-time job-related data and using ArcGIS Velocity to process the data. I would also employ real-time analytics to identify trends and correlations.

Campbell Week 4

WEEK 4

  • Spatiotemporal data can be categorized into the following groups: moving (lives feeds of airplanes, buses, cars, trains, etc.), discrete (criminal incidents, earthquakes, geotagged social media feeds), stationary (wind speed and direction measurements at weather stations, highway and traffic speed, water levels at stream gauges), and change (perimeters of wildfires, flooded areas, land use and cover) 
  • Real time GIS handles current and continuous data, which can be the latest position, speed, altitude, direction,  temperature, pressure, concentration, or water level of various sensors and other objects. It can provide better situational awareness, enhance emergency response, and support decision making. 
  • Point in time- refers to time values that are typically stored in a single attributes field (lightning strike)
  • Duration of time- refers to time values that are typically stored in two fields, one for the start time and the other for end time. (wildfires)
  • Time measurement systems- time can be expressed in many units, such as in years, months, days, hours, minutes, and seconds
  • Time reference systems- time zones and rules for daylight savings time (GMT, UTC) 
  • Time representations- how the date and time is written (11/07/2023)
  • Temporal resolution- refers to the time interval in which events are sampled (weather report stations report temp. Every 15 mins) smaller temporal intervals will result in larger data sizes and larger temporal intervals will result in lower temporal resolution
  • IoT is the network of physical objects embedded with sensors and network connectivity that enable these objects to collect and exchange data. Enterprise IoT applications include smart cities, infrastructure management, environment quality monitoring, etc. Consumer IoT applications include connected cars, connected health, and smart homes
  • ArcGIS Analytics for IoT and GeoEvent Server share similar basic components: 1.) Ingest- interacts with various data sources. It provides ways to communicate with IoT platforms, sensor networks, social networks, etc. 2.) process- this component processes real time data received and translated by the ingestion component. It also uses real-time filters that remove events that do not satisfy specified criteria. 3.) outputs- sends processed data to a variety of destinations. 
  • ArcGIS Analyitics is a real-time and big data processing and analysis capability of ArcGIS Online. It includes the following: 1.) feed items- allow users to receive sensor inputs. 2.) real time analytic items- allow users to perform real-time processing of these inputs. 3.) big data analytic items- allows users to access and analyze big data repositories of historical observations. 
  • Poll and Push methods: 1.) Poll- the traditional approach in which a client periodically polls the server to retrieve the latest data. 2.) Push- the new way to serve data in near real time using the HTML5 WebSocket Protocol. 
  • Using the information provided in Ch. 6, I could create an app to illustrate the student body population change over time at OWU. To do this, I would find records of the student body population for each year, then enter that data into a file and upload it. I would then add the title, tags, and ensure that the correct time zone is selected and the PopDate is recognized as a Date field and a Time Field. I would then animate the time-series data so that an illustration demonstrates the rise/fall patterns of student enrollment at OWU up to 2023. This could be useful for OWU enrollment staff to see trends on attendance at the school, and to help enhance the methods the school uses to promote students to come and stay here. It may also be interesting for prospective students to see the trends of the school as well.

  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. 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.

McFarland Week 3

Chapter 3:

  • There are two types of widgets. Basic widgets are functional and perform as app tools. Layout widgets are used to organize basic widgets in pages or windows.
  • There are two categories of widget actions: Message actions listen to triggers and perform actions automatically, and Data actions provide users with a list of actions to perform that can all be selected.
  • It is exciting that there is an entirely different site, other than the app creator, that can be used to display information in a different way. I didn’t realize that ArcGIS Online was so diverse.

Chapter 4:

  • Mobile devices can be beneficial for pinpointing locations in the field.
  • Users can access through browsers, apps on their mobile devices, or a mixture of both.
  • The biggest benefit to using mobile devices alongside ArcGIS Online Apps is the use of location finders to have accurate location data in the field (especially in places where you can’t bring a computer to the field).
  • Unfortunately, the camera on my phone is broken so I wasn’t able to finish the tutorials for this section, but it seemed relatively simple.

Possible Applications:

  • Any situation where data needs to be taken in the field can find a use for the content of these chapters. Especially in situations where the data is location-specific.
