Drones, which are also said to be Unmanned aerial vehicles (UAV) are used in many real-world applications and urban scenarios. Initially, the drones were used only for wars, attacks on terrorists, and spying of specific areas using pilot-less planes. With their presence in the media, their potential is being widely recognized.  People are now using drones in excellent ways.

Drones reduce the costs of projects, enhance productivity, and datasets through improvements in graphics visualization. Improvement in surveying accuracy using drones in construction would help in saving both time and money. Extended use of drones in the construction industry will create new jobs and add value to the economy. The speed and availability can be enhanced in emergency services like locating a missing person and providing a valuable aerial perspective facilitating safe operations for both crews and members of the public. Many large companies are using drones for the delivery of products to customers. Also, it has provided the way for the organizations to keep an eye on wildlife without disturbing their peace in conservation and protection of endangered species.

The challenges of the drones are in providing the safest, most efficient aerospace system with no human pilot onboard. The absence of mandatory standards in place to govern the safety and security of the UAV systems increases the overall risk to safety and security. The use of drones in the urban areas is forbidden because routing density is a crucial challenge that needs to be addressed by the drones. Infrastructure development will be the primary cause that is to be addressed to overcome the disadvantages of drones. The software used by UAVs now are privately owned or project specific having many limitations. Open source programming has to be developed to overcome those limitations.

There is no end to how drones will be used in the future. The next generation of UAVs will be volatile, smaller, more compact, and able to multi-task, depending on the users’ needs. Drones in the future will maintain higher elevations, be furnished with advanced cameras with upgraded zooming systems.
