Disaster Management

1.Risk knowledge• Systematic collecting of data relative to the

events• Risk evaluation

2.Environmental Monitoring and Alert Services• Development of monitoring systems • Creation of a quick and accurate Alert service at

international, national and local level

3.Diffusion and communication• Maximum alert distribution• Clear and simply Alert format

4.Answer Capacity • Creation of national and local systems able to

front the emergiencies.6

Obiectives

Analysis of the format to be used for the Alert Messages

Make the alert message available on mobile devices.

8

CAP – Common Alerting Protocol:

Simple ad general format based on XML for the exchange of Alert Messages on every kind of network Permits the creation of Messages:

• To be distributed on different Alert Systems

• To be used to normalize the information coming from different sources.

9

Functionalities

Flexible Georeferencing – models based on:• Latitude/longitude• 3D Geospatial representation

Messages transmission• Multilanguages and• with multiple targed users

Validation and time out of messages

10

Functionalities

Messages cancelling/updating functions

Models for the definition of complete and valid Alert Mesages

Compatibility with systems based on digital signature

Support for digital images and audios

Conclusions and future developments Management and extraction of informations from

a XML document.

Independency from the execution platform.

Execution and visualization on a mobile device.

Future developments:• Correct management of multiple occourencies.• Selection of the resource containing the messages.• Complex graphycal visualization of the informations

contained in the messages.17
