Walz – Week 4
Chapter 5:
Chapter 5 went a lot over how ArcGIS enterprise works, how this hybrid model is ideal for security but also functionality and how one can use ArcGIS pro to compare tiles on ArcGIS online/enterprise
- Sometimes you may need to build a private WebGIS due to security or functionality reasons
- You can build this private WebGIS through ArcGIS enterprise
- In places with restricted internet like government buildings, will need to use on-premise WebGIS
- ArcGIS enterprise is an on-premise, user managed part of the Esri Cloud. Basically ArcGIS enterprise is just a variation of ArcGIS online
- The specifics on how ArcGIS enterprise is connected to GIS servers are a little bit confusing but it seems to be highly secured
- ArcGIS enterprise like ArcGIS online can create and host multiple web layers with various features
- Many of the GIS products conform to a specific standard in order to keep things uniform
- Can use weblayers from ArcGIS pro for ArcGIS online and enterprise
- I tried doing tutorial 5 but for ArcGIS pro wasn’t working so I plan on reinstalling the application and deleting some old projects as my laptop is running a bit slow from all the downloads, so I will attempt this later
- Though from what it looks like, you can use ArcGIS pro to basically compare with other tiles like vector and raster tiles on ArcGIS online / enterprise
Chapter 6:
- In this chapter, it seems the data file type is csv. Which I believe is what we used for ArcGIS story maps as well. Then from that data you can create a feature layer and then use instant app templates and the ArcGIS dashboard
- Time is an important dimension of ArcGIS; spatiotemporal data can be categorized into these categories; moving, discrete, stationary, and change. Most of these are pretty self explanatory
- On GIS a time value can be either a point of time or a duration of time
- loT collect sensor data that can be shared and presumably update maps in real time
- Lots of smart devices have this sensor feature to get real time data to you
- ArcGIS velocity allows user to capitalize on sensor data for Esri projects
- Dashboards can be updated with real time data, can display things like wind speed, or measles cases
- Tutorial 6 had me explore various ArcGIS applications focusing on real time and temporal GIS. I built a web map with live data layers that showcased things like traffic, and incidents, and then I customized it but I didn’t want to share it. I then created an operations dashboard that visualized real time emergency information, but it was kind of wonky. Afterward I made a time enabled feature layer from historical US pop. data and made it into an animated map and then I did a time aware map that animated 200 years of US population growth, which showed trends over time.
One application idea is creating a time aware map over really any data I could realistically collect or get a hold of that a time aware would make sense. Like for example; looking at urban growth within a city or how wildlife have decreased over time in an urban area.
