Privacy concerns with aerial surveillance.
Requirement of trained personnel to operate sophisticated technologies.

While aerial imaging offers advanced capabilities, its effectiveness heavily depends on weather conditions and the technology's operational expertise.

Advancements in Aerial Surveillance for Forensics

With constant advancements in technology, aerial surveillance has become an indispensable tool in the forensic field. New techniques have enabled investigators to gain better insights and collect crucial evidence without disrupting crime scenes.

Cutting-Edge Aerial Imaging Forensic Techniques

Current trends in forensic imaging have introduced a myriad of new techniques in aerial surveillance:

Geographical Information Systems (GIS): These systems are utilized for mapping and analyzing spatial information.
Oblique Imaging: Captures images from angles other than straight down, offering more depth and context.
High-resolution Zoom Capabilities: Enable detailed examination of distant objects without physical proximity.

All these techniques integrate into a seamless toolkit that facilitates a robust forensic investigation approach.

An example is the use of drones equipped with high-resolution cameras which were crucial during investigations in vast and rugged terrains. These devices deployed oblique imaging to capture detailed images of evidence.

The world of aerial forensics is also embracing Artificial Intelligence (AI). AI algorithms can automatically identify and classify objects within aerial images, a task traditionally performed manually. These algorithms can distinguish between vehicles, people, and various objects, potentially highlighting suspicious activity or evidence automatically.
