The Common Alerting Protocol or (CAP), has its origins in a November 2000 report by the US National Science and Technology Council (NSTC). It recommended a standard method be developed to relay all manner of warnings be it locally, regionally and nationally. In 2004, formal approval was given to CAP 1.0 by the OASIS Emergency Management Technical Committee. Globally, the International Telecommunication Union (ITU) adopted the CAP in 2007. Many other countries and agencies have since adopted the protocol as the standardised national warning architecture.
The benefit starts with the various agencies generating alerts. By simplifying the alerting methodology, systems can be backward compatible, integrated easily and consistent across the many types of early warning technologies and applications.
The CAP is a data format that specifically normalizes “alert” data in a defined structure. The system is based on the XML data format and is backward compatible with existing alert formats such as the Specific Area Message Encoding used by in NOAA weather Radio. Specifications of CAP are available on the OASIS website.
The standard is relatively straight forward to implement. The framework provides a systemized “checkbox” format that defines specifics about an alert. One example is the size or area of the alert. Area can be defined by a geofenced radius or even a complex polygon with decimal longitude and latitude points. Using these coded values makes it easier for various platforms to automatically integrate the alert.
Authorities will usually implement CAP in addition to their existing alerting processes. It normally requires very little investment in new technology. Below are some elements of a CAP alert. Some attributes are required, while others are optional. Refer the OASIS website reference for more on this.
When it comes to dissemination of warnings to the public, authorities have relied on a commercial media such as radio and television. Online social media companies like Facebook and Twitter are often utilized to publish information as well. This information may not be output in the CAP format but for the public that is not as relevant. Google also now shows official messages on their search desktop and mobile pages.
Emergency Managers are often receiving information that is not immediately disseminated to the public. The CAP format allows them to analyse trends or monitor events as they escalate. Things like pattern detection and situational awareness are compiled and decisions need to be made by experts before a warning goes out to the public.
The important distinction here is anyone receiving this information must be confident the source is authoritative – that the CAP feed is official. For that, there is a CAP International register maintained by the World Meteorological Organization and the ITU.
Google launched a public alerts platform in 2012. It is available in mostly English speaking countries. The system essentially provides agencies a way to send an alert to Google via the CAP format. Google will ingest the data and output it to various Google properties – search and maps as an example. As to the question who can publish to google public alerts they define this on the developer page:
“Partners who publish a Google Public Alert must be:
Below is typical example from Google Public Alerts:
When an alert goes out to phones via SMS or even automated calls to landlines authorities don’t make this decision lightly. This method is often subject to network availability and in an emergency people reach for their phones to either report the incident or check where their loved ones are. This has the effect of clogging the network. Authorities put out circulars advising people to limit the use of their phones.
There are some disadvantages using mass media such as radio and television and online platforms to disseminate vital information. In both circumstances the user must do something to receive the information. You need to be watching TV or listening to the radio and be on the correct station/channel. If you are online you could be searching or checking your social media news feed. The user in these circumstances is doing something, making a pro-active decision about accessing and using these services.
Your device (smart phone), packed full of sensors, knows where you are in the world. More and more apps are requiring background location services to be activated to provide you their service. Google Maps is the most obvious.
Public Alerts are a typical use case where geolocation relevant information would be beneficial. There are many examples, but take a terrorist event scenario. There is no point being told to “avoid the area” - in a place, city or country you are not in or even nearby. The user learning of this information interprets it either as a news item or something that will affect them. There is a big difference between a news item and a public alert. The problem with delivering this information on mass or social media, is that it is difficult to localise the information and the distinction between an alert advice and a news item is often blurred
What is required is obvious….
Ideally, if you can receive an alert based on your geo location, you should not need to do anything to be the recipient. You become a passive receiver of information that might be relevant because its applies specifically to your location.
An alert sent to your phone would provide this scenario. In many countries, this is already happening via SMS. However, a push notification would be more effective.
There are a number of differences between a Push Notification and a SMS
Both report a high open rate which is over 90% - much more effective than email.
There are some measures cities and indeed countries can take to better inform the public and one is to make sure people know there is an App they should download. This can be further enhanced by involving stakeholders such as Telco’s and mobile phone companies. An app pre-installed natively takes out the friction or educating the benefits of a public warning. The less people have to do the better.
UgoRound is an app that would benefit every citizen with a smart phone. If you can receive an alert based on where you are, not who you are – your city can step up and take your safety and well-being to another level.
The “city”, would not need to shoulder this responsibility on their own. The platform can be implemented and deployed with any agency tasked with citizen well-being. This multi-agency citizen interaction is happening anyway – normally through social media. The UgoRound app allows you to receive relevant and therefore much more personal information
