Veerjee Week 3

Chapter 3: Experience Builder

This is mostly for a more complicated way to create apps, maps, and more. Things an experience builder could include: components such as pages, windows, and outline views. It could also include various widgets such as functional & layout widgets. Widgets are classified into two groups, message actions & data actions. When using a message action, it listens to various triggers and performs assigned actions. For data actions, they provide actions to a button that users are able to click on, a usage could be to export records to a file. 

  • Tutorial 1: Creating a basic webpage that included 2 different maps, an image, and methods of switching between the two of them through a view selector. 
  • Tutorial 2:This was more about how to create various actions for the data, in this case it was the action of making sure the the maps of 2d & 3d match, and with selections when the 2d points are selected, only those ones will appear on the 3d map. These are done by utilizing the action tab that appears once map tabs are selected under the outline window.
  • Tutorial 3: This was mostly about how to add a text box that included statistics. It is fairly similar to things we have done in ArcGIS pro, except as a presentation-like format. From this point forward, I have realized I am messing up the styles/formats of the web experience, however I am going to just add the features & try to salvage it as best as I can.
  • Tutorial 4: This tutorial was about how to create a table & how to make it so it displays certain fields in a specific order. Also adding a search bar & filters for the data.
  • Tutorial 5: When adding a filter I will want to use an SQL expression to ensure that the map itself flows. I can choose various criteria that I want my maps to be filtered by. I got pretty lost halfway through, but from what I am able to judge, I am also able to make filters for the table that I had added in the previous tutorial  & also be able to make a donut chart. And when going through the actions, I am able to trigger something to spawn a chart for various data that I give said chart. 
  • Tutorial 6: This felt like it brought everything that we have made together, and I believe I misunderstood some instructions referring to the cosmetic effects of the main page. This tab was about making a header & more pages with the ability to swap between them.

Chapter 4: Mobile GIS

There are many reasons why Mobile GIS is useful, such as mobility, locational awareness, ease of data collection, real-time info, large user volume, and many ways to communicate. GIS is useful in a bunch of different technologies. I will want to be careful in concern to the utilization of the web interface as phones are needing more simplistic designs. There are three main schools of thought when it comes to app development strategies: 

  1. Browser based – which is using apps through mobile web browsers. This will be fairly limiting the user’s experience as it will not be utilizing the phone’s features.
  2. Native-based approach – which will be using a mole app, a disadvantage for that would be learning skills for the coding languages 
  3. Hybrid-Based approach – A combination of both native & browser based approaches
  • Tutorial 1: To get to the ‘set rule’ option, go into edit, then find ‘behavior’. And instead of ‘If show’, go to the thing you want to see, and then select the conditional. This is very similar to a software such as Google Forms
  • Tutorial 2: I thought it was fairly cool that I could use Survey123 to submit data from my phone. It seems fairly intuitive to collect data & be able to check them out using the page.
  • Tutorial 3: I had gotten very lost early on in this section. I think it is because I screwed something up within the tutorial section for the surveys. However from what i can gather, thiss will be tying the survey itself to sync with a feature layer by going into where the survey is collecting responses. I can add a new field for the various different types of data being collected and make them appear as points on the map. And they will appear as lines within the map. 
  • Tutorial 4: Same issue as tutorial three, but here is what I was able to gather from the tutorial, this will be adding some form of visibility layer with conditional statements. This will be done by adding another layer, and adding various expressions to make it “Incident_Type == Pothole”, for example. And this will allow a user to filter the different types of data within the map. 
  • Tutorial 5: It appears that in this tutorial I am able to use another app in order to compile data to put directly into my field map rather than filling out a form to put into the map by using skills from tutorial 4.
  • Tutorial 6: In tutorial 6 we are using the map created in tutorial 3,  this will be using the quick capture software to do. And this will be a great way to include a user-friendly app interface that includes icons for each type of thing you want input on. 
  • Tutorial 7: This is just showing how to utilize what was made in Tutorial 6.
  • Tutorial 8:  Utilizing AR will be a way to add more context for the things made in the previous sections. 
  • Tutorial 9: Utilizing AR will be a way to add more context for the things made in the previous sections.

 

Application description based on Ch 3 & 4 using my data:

  • Create a web experience. (Ch 3)
  • Creating a survey form for a department to report suspicious activities will be a really good use for GIS tech, maybe creating something for Public Safety? (Ch 4)

Johnson Week 4

Real-time GIS has the ability to ingest real-time data, real-time visualization of data, GeoEvent and velocity, alerting, update schema, add  additional processes, ArcGIS online feed items, and feature layers. In Chapter 6, these abilities are touched on as well as allowing the ability to see different patterns over time. For example, a map tracking real-time traffic in an area also has the ability to go back days, weeks, months and even years and display objects, traffic patterns, weather patterns, and accidents that allow people to use this information and make inferred guesses on how these patterns will carry out in the future.

Application Idea: Having previously worked at Planet Fitness for 2 years, a gym that alleges a no judgment zone, we had a popularity tracker that was on our website and app. On it, guests could see what hours were most popular pertaining to visitation rates, hours that were slower, and recommended times to go. All of this information was kept up to date with real-time statistics coming in based off of the check in swipes of guests. That being said, this information was not specifically Real-Time GIS, but the design is relatively the same. After seeing different maps based on population and traffic patterns, I thought a good idea would be to implement something for OWU students, or even just Delawarians that businesses and eateries could use for every customer and person either using whatever said facility or are present. This could help for busier times such as First Fridays, to let people know how many people are present, inferred wait times, and other places that are less busy. The same would be true for OWU campus in regards to dining halls.

Roberts Week 4

Chapter 6: The introduction of chapter 6 talks about incorporating real-time data into ArcGIS Web apps and touches upon the idea that there is technology all around us that can be used in such programs (ex. all the technology in a smart home). I saw an example of this in week one when we looked for applications of ArcOnline resources when I found the web app that monitors weather stations throughout the United States (when the program was active).  When moving onto the tutorial, I found the dashboards feature to be pretty straightforward. I also forgot that I made one in 291 until I saw the dashboard under my Content page, but I think I understand the functions of the dashboard app more than I did in the Spring. I did have an issue with the advanced options while making my current dashboard and was not able to get the heart icon to appear despite double checking the code I entered compared to what the textbook instructed. This was a little disappointing, but I was glad that the other coding for highlighting and coloration did not give me any issues. I liked the resulting visuals from the instant app even though it took me a frustratingly long time to figure out how to change the title after a spelling error. I could see the slider being helpful for displaying other chronological data as well, but would also be interested in exploring other similar instant apps on my own time.

Assignment: One of the ideas that I could create using ideas from this chapter is a dashboard for people in Ohio to use before they would go on a hike or other outdoor excursion. The dashboard could include real-time weather updates and have a map that includes information about trails. Another option could be to use the Delaware data and create an animation similar to the one in the tutorial that shows the development and distribution of buildings and land parcels over time.

ArcGIS Experience Builder and Mobile GIS are powerful tools within the ArcGIS suite, offering flexible and user-friendly solutions for creating and using geospatial content across various platforms. ArcGIS Experience Builder enables users to create web experiences with minimal coding by using drag-and-drop functionality and integrating widgets to interact with both 2D and 3D data. Users can start with templates or build from scratch, customizing layouts for mobile optimization, adding themes, and employing a range of widgets (e.g., maps, legends, charts, and survey tools) to enhance interactivity. The tool’s flexibility allows for integration with ArcGIS Online, ArcGIS Enterprise, and ArcGIS API for JavaScript, making it adaptable for diverse mapping applications.

Mobile GIS, on the other hand, brings traditional GIS functionality to portable devices such as smartphones, tablets, and laptops. It offers easy access to geospatial data, real-time updates, and interactive mapping through apps like ArcGIS Field Maps, which supports field data collection and management. Mobile GIS leverages GPS, wireless communication, and mobile operating systems to allow users to track, capture, and update data on the go. However, smaller screens can limit visibility and detail compared to desktop versions. Together, ArcGIS Experience Builder and Mobile GIS can support a variety of applications, such as studying and monitoring gas leak patterns in Delaware County. This project could ensure the safety of residents by using interactive maps, data analysis tools, and additional data collection methods beyond traditional surveys.

I messed around with an interactive soil map where my locations where i sampled soil for my independent study were marked and had pop ups with the photos of different land use in the area.

Dodds Week 2

Chapter 1: Getting Started with Web GIS
Web GIS brings together the internet and geographic information systems (GIS), making it easy for people to use geographic data from anywhere. It’s becoming popular in areas like government, business, science, and even day-to-day life. Web GIS has tons of applications, from mapping and data management to analytics and decision making. The main pieces of Web GIS include users, groups, content (like maps and data), and metadata. Apps are where the action happens, things like StoryMaps or mobile apps that let users interact with maps and data. Inside these apps, you’ll find basemaps (which give context), operational layers (for interactive data), and tools that help with things like routing and location searches.

Chapter 2: Smart Mapping and Storytelling with GIS
Chapter 2 dives into tools for making maps that look great and tell stories. Feature layers are the most common type of interactive layer in maps, and they’re reusable across web maps, scenes, and apps. Esri’s geospatial cloud hosts lots of these layers, letting users create custom layers from their own data, templates, or even from scratch. With smart mapping tools, you can make professional-looking maps: think heat maps, dot density maps, and color-coded comparisons, without needing a ton of technical skills. ArcGIS Living Atlas is also a go-to for ready-to-use layers that include basemaps, imagery, and details about things like infrastructure and the environment.

For my project I would like to do something with bird sightings around campus. I was inspired by crowd sourced information and love creating free resources. I could highlight 2-3 species of interest.

Norman Week 1

oduction:

I think that the ArcGIS living atlas of the world is a really interesting tool. I played around with it a little bit and it was cool. I also like the incorporation of using different web layers in your maps.

Tutorial: 

I found the tutorial fairly easy except for some features were a little different than they were described. It didn’t really trip me up thought. I thought it was a good overview of how to use the software and I feel like I will be able to use it successfully. The basics mostly seem pretty intiuitve.

GIS Uses:

I looked at uses of GIS in transportation planning, which is something I am interested in. I found a few interesting uses including traffic flow managment. It also helps with public transit planning in analyzing things like population density, planners can determine where stops and transit sites should be. Another way it can help with transit planning is through route optimization.

Veerjee Week 2

Chapter 1: There are a lot of reasons to be using webGIS for more major projects that are meant to be publicized. Some of the reasons they have listed are: Global reach, large number of users, low costs per users, better cross-platform capabilities, ease of usage, and easy to maintain. Some of the main organizations or reasons to use it, and reasons why I may use it in the future are for Business and Governmental use, however I was interested to see that people use Web GIS for their daily life. A majority of the stuff brought here seem fairly basic, yet good information to keep in mind while working on maps. Such as the dominance that phones currently hold in the information technology world for the average person. It also reminds us on how some of the different types of data interact. The first tutorial was more about how to upload data into webgis & share it. The second tutorial was more about how to add a field and add some data through the web page. The third tutorial was about how to add the feature layer into a proper web map. I had not been able to find the community map, so I decided to just use the streets map. It was pretty cool to make a functioning webpage for a map.

Chapter 2: This chapter overall is a little more ‘intense’ than the previous one. There is a lot of focus/emphasis on the creation of feature layers and the techniques of doing these feature layers. Tutorial 1 had a good review on how to implement data & how to change a few of the fields’ names. Tutorial 2 had more symbiology work, in this case it was a comparison between the population of 10 years prior and to a set date. Tutorial three was pretty cool by having me create an expression and using the data to appear on my pop-ups, I know that I will need more practice doing this to fully remember it. Tutorial four was about how to add various types of media in the popups window, particularly links, images, and charts using the data that is saved in the csv. The fifth tutorial I got stuck on towards the end as I was a little confused on how the map actions worked, however the rest was fairly intuitive as it was setting up a storymap. I think these will be pretty interesting to utilize, especially for things like the trip project that I will likely be doing. Tutorial 6 was more about how to add a swipe block to use map activities. I will likely want to use this for if I were to make a story map to say ‘hey, we will be going here, here and here’, which may be a great strategy for the vacation idea.

Description of an application of WebGIS using my data or that from Geog 291:

  • Landmarks around my city. I can find a bunch of important buildings and take pictures of them from my city. As my hometown is so small, I will likely be able to find or take pictures over a weekend. I will then attach it all to a single map and make an app out of it. (Ch 1)

Roberts Week 3

Chapter 3: This chapter’s tutorial was a bit more complex than the previous ones and took me longer to complete. I ran into several minor issues including a missing dynamic content button and the fields pane being empty when writing expressions in the text box. Fortunately I was able to work through both issues after visiting the ESRI community page and finding a comment and solution for the exact issues I had. Later on I had an issue where a ‘sort by’ value that was listed in the book wasn’t an option for me to select, but it appears that my chart still matched the information that I wanted it to present. I also noted that when the book instructs you to type a URL you need to add ‘https://’ to the URL even if it is not mentioned in the tutorial, otherwise the URL will not work. It seems like the experience builder app has a lot more functions to unpack and practice, but I would imagine that after using it several times it could be very helpful in interactively displaying data.

Chapter 4: I enjoyed this chapter and found it much easier to figure out than the previous chapter. I did run into several issues in which the book was not similar to the screen as a result of an update, so I had to use trial-and-error to figure out how to proceed. For example, the ‘set rules’ setting for the incident type question was completely different from what the book showed, so I actually had to instead edit the dependent question’s rules to get the same result as the textbook. The tutorials of the different apps were interesting and I could see how they could become useful, but it was inconvenient that each app was its own entity and had to be downloaded seperately.

Assignment: I think the survey feature could be useful in monitering invasive species, so creating an app to report sightings of spotted lanternflies in a region could be efficient. The ability to add locations and photos would also make the survey especially convient. Another idea I had was to use the web experience as an interactive way to display information about natural landforms in Ohio or state parks.

Note: I completed the Delaware data inventory when I was in Geog 291.

Keckler Week 3

Working with 2D and 3D maps for chapter three was not nearly as exciting as the previous two chapters. I found working with the 3D for the tutorial to be a hassle more than anything. After completing the tutorials, I still do not see the point in having a 3D feature to represent hurricane and earthquake events. I also had issues configuring my table widget; there was not any space to fit it anywhere, so the widget is awkwardly overlaying the map. Otherwise, everything else went fairly smoothly after accounting for some changes between the tutorial and software over the past couple years.

Chapter four was peculiar to me in that it seemed like a glorified advertisement that demanded the download and use of different apps only for them to be used over a brief period of the tutorial. While mobile accessibility is becoming more necessary, the limitations of a mobile device concerning computing power make it pale in comparison to working on a PC. Why download three apps when I could just open three tabs on my laptop in half the time. Right now, I feel like the PC is more efficient than mobile. Despite that, I did find it valuable to put different GIS apps to use for this tutorial.

A couple ideas that I have for potential apps are to make an app showcasing parks and nature preserves around Delaware or an app that uses survey inputs to document squirrel sightings on campus. Showcasing natural areas in a 3D setting would show off landscapes better than a basemap overview on GPS. A map about squirrel locations would be fun since squirrels are common on campus, and there would be no shortage of potential submission material for interested parties.

 

Delaware Data Inventory:

Street Centerline: This layer shows every paved road in Delaware County intended for appraisals, emergency response, reporting, ODOT, and other related purposes. Around the Delaware State Park- just north of Delaware City- the paved surfaces within the park are drawn like squiggly hands. There are more dead-ended roads than I expected there to be.

Zip Code: This layer shows each zip code within Delaware County. These codes were changed in 2003 in response to the 2000 census, but this layer in particular was made in 2005 and is updated regularly. This layer was used for attributes in the centerline. The zip code for Delaware City is 43015, and my home’s zip code, 43334, is included in a minute portion around the northeast most edge of the county.

MSAG: The Master Street Address Guide is made to conveniently identify the boundaries of cities, villages, and townships within Delaware County. There are 28 political jurisdictions within Delaware County, so this dataset clarifies those boundaries.

Recorded Document: The points on this set are meant to correlate within documents in the Delaware County Recorder’s jurisdiction that are not included in active subdivision maps that show the details about the property. Looking at the different points, I am still not exactly sure what information would be held about the points. There are many points that are in people’s backyards or in streets; the points just reference a page in a book, but the relevance of these points is unclear.

Survey: Each point represents where a land survey has been conducted within the confines of Delaware County excluding surveys from Old Survey Volumes (1-11). In addition, each point is connected to a file with information on the land survey.

Parcel: This dataset identifies the legal boundaries of properties within Delaware County. You can find all sorts of information about people’s homes in this map including Land Value, Number of Bedrooms/Baths, Tax Numbers, etc. If you view different campus buildings, the owner is listed as Ohio Wesleyan University, Trustees OWU, or TR Ohio Wesleyan University.

GPS: GPS monuments established in 1991 and 1997. This set is strange in that what exactly the monuments are is unclear- even when searching through the pop-up. For example, if you click on the blue dot in between the observatory and Stuy, the name of the monument is just “Delaware,” and there is little supporting information about each particular monument within the set.

Precinct: Identifies the bordering of voting precincts in Delaware County. Each precinct name includes the township or city name sometimes followed by a letter and number if the township contains multiple voting precincts.

School District: Every school district within Delaware County; this data was originally acquired through the county auditor’s parcel records. School districts within the county include Big Walnut, Buckeye Valley, Delaware, Olentangy, and others. Fun fact: The school that I graduated from, Highland, is in a small section of the county similar to my home’s zip code.

Subdivision: There are many condos and subdivisions- specifically concentrated in the southern half of the county nearing the Franklin County and Columbus area. Subdivisions include areas of land that are split into smaller sections/parcels to be sold. Some subdivisions that I found predominantly included farms, condos, and what I presume to be those exclusive housing developments.

Township: The 19 townships of Delaware County. Delaware City is an interesting case with how the layer is organized. The central part of Delaware has a township name of “Delaware.” Meanwhile, there are smaller sections inside and around that mass with the township name of “Delaware Township.” A similar phenomenon happens with Orange Township and Berkshire Township.

Tax District: All tax districts of Delaware County with Tax District codes. The city of Delaware is broken up into many tax districts. Some tax districts cover a wide area of land while some encircle a few houses. Tax District 50 is just a block that surrounds Delaware Fire Station #303.

Address Point: As stated in the title, this set contains each address in Delaware county. Intended mostly for emergency response systems using reverse geocoding. I did find an address point within a pond in the Sheffield Park in between the Alum Creek Reservoir and Hoover Recreation Area (X: 1849668.892400, Y: 191484.601000).

Annexation: This set shows land that has been annexed between 1853-present. Annexed land includes the Delaware City Area, Ashley, Ostrander, Sunbury, and other areas in the southern edge of the county.

Condo: The bulk of condominiums within the confines of Delaware City are in the southern end of the county near Franklin County and the Columbus area- just like how the subdivisions are. The Powell area appears to be one of the most densely populated with condo units compared to other areas in the county.

Municipality:  This layer showcases the boundaries of Delaware, Sunbury, Galena, Powell, Ostrander, Shawnee Hills, and parts of Ashley, Columbus, Westerville, and Dublin that are all present within the Delaware County lines. There are holes within the Delaware Municipality, though. 

Building Outline 2023: This layer contains every building within Delaware County as of 2023. There are structures that appear on the map that are not highlighted as a building, so I wonder if those are sheds, barns, garages, a patio, or something else that does not fit into the criteria to be considered a building. It could be that the basemap itself has not been updated to accommodate the exact changes in buildings.

Delaware County E911 Data: Certified addresses within Delaware County intended specifically for 911 agencies for emergency response. I could not actually interact with this dataset past its summary.

PLSS: Public Land Survey System are meant to show the boundaries of the US Military and the Virginia Military Survey Districts of Delaware (two PLSS). The map is organized in orderly rectangles except for the westmost edge of Delaware County where the shapes are variable. The orderly rectangles denote the boundaries of the US Military PLSS while the unruly shapes denote the boundaries of the Virginia Military PLSS.

Farm Lot: Farm Lot boundaries within the US Military and Virginia Military Survey Districts in Delaware County. According to the set, all of the land in Delaware county is within a farm lot boundary.

Original Township: There were still 18 townships within Delaware County. A majority of these townships were arranged in rectangles while the westmost townships were shaped more erratically. Similarly to how the PLSS boundaries are currently.

Dedicated ROW: Right-of-Way; public roads where transportation, driving, bicycling, and walking is permitted to take place. Roadways not included would likely entail areas where through traffic is not welcome. This layer was created through the Parcel data.

Building Outline 2021: Building outlines for every structure in Delaware County in 2021. Can compare with Building Outline 2023 to monitor new development over the past couple years within Delaware County.

Map Sheet: These are the map sheets of Delaware County. Our campus is split into three: Sanborn and the sororities, residential side, and academic side. Otherwise, there is no clarification on why the map sheets have been arranged or any other details; there are just map sheets compiled into a layer over the basemap of Delaware County.

Hydrology: This layer shows the major waterways in Delaware County. There are 24 major waterways that pass through or reside in the county. Nearby, there is the Delaware Reservoir with the Olentangy River flowing into it as well as through Delaware City with the Delaware Run- which runs through campus- connecting to that river. Then, there is the Alum Creek Reservoir; I personally enjoy visiting the dam there.

ROW: Right-of-Way designations for roads in Delaware County. This is updated through updates in the Parcel data, but the map itself is not functioning at the moment.

Delaware City Contours: I could not access this layer!

Here is a teensy bit of my hometown as a bonus!

Johnson Week 3

Chapter 3

ArcGIS Experience Builder is a tool that allows you to create different types of content, that does not require exuberant code to do so / very low code. Along with the creation of different content, some specific methods of using this tool are widgets, 2D and 3D data can be drag and drop interface, custom tools, integration of other apps, mobile optimization (mobile GIS down below), and different templates.

 

Chapter 4

Mobile GIS is a combination of the traditional GIS software onto a smaller piece of technology– something that is portable, (i.e. cellular phone, tablet, laptops). MobileGIS provides access to downloadable geospatial data, printable maps and interactive mapping applications. While Mobile GIS does have relatively amazing abilities for the physical size of technology the program is being run on, the smaller size of the screen causes lack of visibility to some degree. 

 

Application: Based on some data that I have seen using applications of Mobile GIS and ArcGIS Experience Builder, I think that having a study and inspection of areas affected by gas-leaks over the last 10 years within Delaware County lines. Many people are affected by spontaneous gas leaks, but also ensuring that these are solely spontaneous, are not occurring in patterns, and studying the areas and the people affected by these would ensure the safety of people and animals nearby. Along with this, some sort of method of obtaining information besides surveys and technological monitoring devices should be used.
