Drones are used for real estate for several purposes, including:

1. Property inspections: Drones equipped with cameras and thermal imaging sensors can be used to inspect properties, such as homes, commercial buildings, and land, reducing the need for manual inspection and minimizing the risk of injury to inspectors.
2. Aerial photography and videography: Drones equipped with cameras can be used to create aerial photographs and videos of properties, providing a unique perspective that can help market and sell properties.
3. Surveying: Drones can be used to survey land and generate detailed maps, providing data that can be used to support real estate transactions and improve land use planning.
4. Environmental assessments: Drones equipped with cameras and sensors can be used to assess the environmental impact of real estate developments, such as monitoring wildlife habitats and detecting potential pollution.
5. Security: Drones equipped with cameras and sensors can be used to monitor properties, improving security and reducing the risk of theft or vandalism.

These are some examples of how drones are being used for real estate to improve efficiency, reduce costs, and support real estate transactions.
