Keywords

💡Paper Maps

Paper maps are traditional, physical representations of geographic areas that have been used for navigation and orientation. In the context of the video, they symbolize outdated technology that has been largely replaced by modern devices. The script mentions that 'for many, paper maps are becoming obsolete', highlighting the shift towards digital solutions for navigation.

💡Mobile Phones

Mobile phones are portable electronic devices that combine communication and internet capabilities. They play a central role in the video as modern tools that have replaced paper maps for navigation. The script refers to mobile phones as 'our mobile phones and Google Maps' that guide us from point A to point B, indicating their utility in providing real-time directions and information.

💡Search and Rescue

Search and rescue (SAR) refers to operations that aim to locate and assist people in distress, typically in remote or dangerous environments. The video discusses the challenges faced by SAR teams, such as 'rescuing mountaineers who have fallen into difficulty,' and how technology can enhance their effectiveness. The script mentions using drones to locate injured individuals, showcasing the application of technology in SAR missions.

💡Drones

Drones, also known as unmanned aerial vehicles (UAVs), are aircraft without a human pilot aboard, controlled remotely or flying autonomously. In the video, drones are depicted as tools that can be equipped with thermal imaging cameras to locate people in distress. The script describes how drones can be 'mounted with thermal imaging cameras' to find individuals, but the challenge lies in transmitting the data back to the control center due to poor antenna reception.
