TRANSCRIPT
AEGIS: Wildfire Prevention and
Management Information SystemProf. Kostas D. Kalabokidis, Principal Investigator
University of the Aegean, Mytilene, Greece
• Large wildfires (mega-fires) in North & South America, Australia, Russia and the Mediterranean burned vast areas in the 21st century
• Climate change, overpopulation, overconsumption, "non-sustainable development"
Wildfires are ravaging our World!
• Greek firefighting strategy does not integrate a holistic system of geospatial and decision support tools
• Large number of systems exist; few of them can be considered fully integrated solutions
• EFFIS in EU, WFDSS in the US, CFFDRS in Canada
Wildfire Decision Support Systems
Challenge: Instant access to
functionalities
conduct fire analysis based on need, without thenecessity to install complicated software

The AEGIS System
• AEGIS: integrated approach to wildfire decision support, designed for use by the civil protection authorities of Greece
• End users interact with AEGIS through a Web-GIS platform and a Windows Phone application
7 different study locations around the country of Greece (i.e. 10% of the total Greek territory) with high-hazard, high-value and high-use forest and other multi-purpose areas
Study areas
Services provided by AEGIS
– Fire analysis (fire danger & behavior)
– Historical fire data
– Topographic & satellite maps
– Weather measurements
– Weather prediction maps
– Land use / land cover types
– Road network and fire management data
– Fire management tools (e.g. elevation profile, shortest routes to closest firefighting facilities, real-time images of high-risk areas through web cameras)

Fire management tools
• Parallel computing techniques (High Performance Computing –HPC, and Cloud Computing) to ensure both computational power and speed.
• On demand fire behavior simulations are conducted in an HPC cluster inside a Datacenter on-premises (Aegean University Campus).
• Seasonal burn probability outputs are first conducted in the Cloud infrastructure of Microsoft Azure and then finalized in the HPC cluster.

Parallel computing scheme
• By taking advantage of the Cloud's ability to increase/decrease the number of available VMs on demand, end users are charged only for their consumed processing time and only during the actual wildfire confrontation period.
• On demand fire simulations are better suited to run on premises than in the Cloud. This is because of the significant amount of time overhead (approximately 15 min) required to allocate new VMs in Microsoft Azure.
• On demand fire behavior simulations need to be conducted instantly and thus, time overheads should be minimized to achieve a timely and effective response when a wildfire breaks out.

AEGIS vs. other related systems
• Mobile application for wildfire information management that operates on Windows Phone devices
• Acts as a complementary tool to the web-based version of the AEGIS platform
• Digital assistant for artificial intelligence “Cortana” (developed by Microsoft for Windows Phone devices) allows information utilization through voice commands

EFFIS App
Forest Fire Danger Meter
Wildland Fire Behavior App
Mobile Apps in wildfire management
• Fire Data: access to fire management data• Position: re-calculates the current position
of the end user and re-centers the background map
• Weather: access to current weather conditions
• Directions: enables the calculation of the shortest route between the current location and a different location specified by the user
• Change Basemap: switch the base map scheme between Bing Maps and Open Street Maps
• Login: allows authenticated users to publish a new wildfire event in the web-based platform of AEGIS
Functionalities
• Cortana is a highly advanced artificial intelligence system for the Windows Phone platform. It allows end users to execute the desired functions via their mobile phone, simply by using corresponding voice commands.
• The voice commands are executed in an automatic and transparent to the user way and the result is visualized on the screen of the mobile phone without any further user intervention.

AEGIS App & AEGIS web-
based system
• The innovations in AEGIS provide advanced tools for firefighting personnel, emergency crews and other authorities to facilitate operational planning for wildfire incidents.
• Valuable assistance and decision support tools can be provided to the local authorities responsible for wildfire management to extract useful information as part of an operational wildfire prevention and management plan.
• Resources can be more easily shared among fire agencies, thus reducing costs and enabling efficiency for suppression operations.
