A groundbreaking technology that combines satellite data
and numerical model data for forest fire detection has been
developed, offering a more comprehensive and adaptable approach
to monitor and respond to wildfires. This innovative solution,
developed by Professor Jungho Im and his team in the Department
of Civil, Urban, Earth, and Environmental Engineering at UNIST,
has the potential to significantly minimize the damage caused by
medium and large forest fires.

Traditional wildfire detection systems have relied solely on
satellite data for over two decades. However, the research team
led by Professor Im sought to enhance the existing approach by
integrating numerical model data used in weather forecasting. By
combining various data, including relative humidity, surface temperature,
and satellite observation angle, the team developed a deep learning model
with a dual-module convolutional neural network (DM CNN) structure to
independently extract and combine satellite and numerical model data.
The developed technology was compared to widely used detection technologies such
as MODIS/VIIRS, AHI, and AMI. Existing methods struggle to accurately detect
forest fires due to mixed signals caused by factors like humidity and sun position.
In contrast, the model developed by Professor Im's team considers multiple
variables simultaneously, providing a significant advantage in maintaining
detection accuracy despite changes in the environment.
Real-world experiments were conducted to validate the technology's performance
under various environmental conditions. The results demonstrated that the
developed model outperformed existing detection methods, showcasing its
ability to more accurately locate wildfires. Although the satellite resolution
is lower compared to narrow-range detection technologies, the wider spatial
range covered by the model (4㎢) compensates for this by offering higher accuracy.
"This study maximizes the advantages of deep learning, enabling the convergence
of heterogeneous data with diverse characteristics," stated Professor Im.
"It represents a significant achievement in proposing a new direction for
global forest fire detection technology."
This breakthrough in forest fire detection technology brings us closer to
a more effective and proactive approach in monitoring and responding to
wildfires. By leveraging the fusion of satellite and numerical model data,
this innovative solution has the potential to revolutionize the field of
wildfire management and protect vulnerable ecosystems and communities.
