This week’s emerging theme focuses on the topic of looking at disasters and maintaining situation awareness in (near) real time. To complete this section, you will need to:
- review a short video and reading to get you started;
- use ArcGIS Online to create your own emergency response dashboard;
- identify and add live data feeds to your dashboard;
- conduct analysis to develop situation awareness that can be used to target response resources; and
- write a short report summarizing your work and findings.
Real-Time Mapping and Spatial Analytics
For this exercise, we are going to focus primarily on the Solutions for Emergency Management apps that have been developed by Esri and are based on their suite of ArcGIS technologies, especially cloud and web-based GIS services. Also, see Esri’s Disaster Response Program website for the help the company offers during emergencies. There are other systems out there, some that leverage major industry platforms and some that are developed in-house from open-source software (e.g., recall InaSAFE, PDC, and even Google Crisis Response).
Regardless of the system being used, they have similar goals such as providing:
- base maps and other datasets that can be prepared beforehand and deployed during an event, e.g., road networks, building footprints;
- infrastructure for communicating with a range of stakeholders from local first responders, EOCs, specialists working at a distance, and the general public;
- a means to upload data, including real-time, from the field and other sources;
- rapid analysis and then uploading and sharing derived products, e.g., spatial data analytics, rapid image processing for damage assessment; and
- visualize diverse datasets in an easy to update and understandable format, e.g., multiple map displays on a dashboard with other charts, figures, and video feeds.
Before developing your own situation awareness app, have a look at the two videos and the optional reading below. The first (short) video is an overview of a case study where these approaches are used by the California Office of Emergency Services (Cal OES). The second (longer) video provides more detailed examples about incorporating live data feeds into a situational awareness app and dashboard using Esri tools. These concepts are further discussed in the optional reading from The ArcGIS Book.
ArcGIS Online Case Study: Emergency Management – Cal OES (3:54 minutes)
Leveraging Live Feeds for Situational Awareness (55:39 minutes)
I know this is a long video. If you don't have time to watch the entire video, please have a look at the first 10-15 minutes or so.
Chapter 9: Mapping The Internet Of Things from The ArcGIS Book
As a companion to the two videos, you might want to have a look at this book chapter from Esri. At least keep it in mind as a resource as you work through the rest of the exercise.
There is no Emerging Theme Discussion this week.
The next page will provide you with the details of the Exercise and writing assignment that are due this week.
