Exploring Bhutan’s Hidden Treasures: A Comprehensive Guide to Drone Mapping

Bhutan, a small kingdom nestled in the Eastern Himalayas, is known for its stunning landscapes, rich culture, and Gross National Happiness index. The country has always been protective of its environment and cultural heritage, which has helped preserve its pristine beauty. However, the rapid development and urbanization have led to a growing need for accurate and up-to-date geospatial data to support sustainable development and disaster risk management. This is where drone mapping comes into play, offering a comprehensive solution to explore Bhutan’s hidden treasures.

Drone mapping, also known as aerial surveying or remote sensing, is a cutting-edge technology that uses unmanned aerial vehicles (UAVs) to capture high-resolution images of the Earth’s surface. These images are then processed using specialized software to create detailed maps, 3D models, and other geospatial products. In recent years, drone mapping has gained significant traction in various industries, including agriculture, construction, and environmental conservation, thanks to its accuracy, efficiency, and cost-effectiveness.

In Bhutan, drone mapping has emerged as a powerful tool to support the country’s development goals and environmental conservation efforts. The government, in collaboration with international organizations and local partners, has been actively exploring the potential of drone technology to address various challenges, from mapping remote mountainous areas to monitoring land use changes and natural disasters.

One of the most notable initiatives in this regard is the Bhutan Drone Map project, which aims to create a comprehensive and up-to-date geospatial database of the country. Launched in 2018, the project is a joint effort between the Bhutanese government, the World Bank, and the Centre for Global Engineering at the University of Toronto. The project has already covered more than 20% of the country’s land area, generating high-resolution orthophotos, digital elevation models, and land use maps.

The Bhutan Drone Map project has several key objectives. First, it seeks to provide accurate and reliable geospatial data to support the country’s sustainable development and disaster risk management efforts. This includes identifying areas prone to landslides, floods, and other natural hazards, as well as monitoring land use changes and urban expansion. Second, the project aims to build local capacity in drone mapping and geospatial analysis, ensuring that Bhutan can continue to benefit from this technology in the long run. Finally, the project serves as a showcase for the potential of drone mapping in other countries and regions facing similar challenges.

One of the most significant achievements of the Bhutan Drone Map project so far has been the successful mapping of several remote and inaccessible areas, such as the high-altitude wetlands of Phobjikha Valley and the rugged cliffs of the Haa Valley. These areas are home to some of Bhutan’s most unique and fragile ecosystems, as well as important cultural and historical sites. By providing detailed and up-to-date geospatial data, the project has enabled the government and local communities to better understand and protect these hidden treasures.

Moreover, the Bhutan Drone Map project has also demonstrated the potential of drone mapping for disaster risk management. In 2019, the project team used drones to map the aftermath of a massive landslide in the Punakha Valley, which had blocked the Mo Chhu River and created a dangerous flood risk. The drone-generated maps and 3D models allowed the authorities to quickly assess the situation and plan an effective response, ultimately preventing a major disaster.

In conclusion, the Bhutan Drone Map project is a shining example of how drone mapping can help countries like Bhutan explore their hidden treasures and support sustainable development. By providing accurate and up-to-date geospatial data, building local capacity, and showcasing the potential of this technology, the project is paving the way for a brighter and more resilient future for the Land of the Thunder Dragon.
