Drones Geographic Mapping
The Challenge
Geographic mapping in Nepal’s remote and high-risk regions, such as mountainous terrain and riverbanks prone to flooding, is a critical need. Traditional methods of aerial mapping using aircraft are expensive and suited mainly for large areas, but impractical for smaller, isolated zones.
Without detailed and timely geographic data, communities remain vulnerable to natural disasters like landslides and floods, and authorities have limited tools to plan or respond effectively.
The Solution
To address this challenge, a collaborative project between the Robotics Association of Nepal (RAN) and students from Avans University of Applied Sciences (AVAN) has developed a drone-based mapping system. The drone is capable of capturing very high-resolution imagery, and generating 2D and 3D maps of areas that are otherwise difficult or dangerous to reach.
The system is designed to be used by both professionals and amateurs, and offers a low-cost alternative for rapid geographic assessments in times of urgent need.
How it Works
- Captures aerial imagery for the production of topographic and thematic maps
- Generates orthomosaic images, as well as 2D and 3D models of the terrain
- Designed for use in hard-to-reach locations, such as mountain peaks and high-flow river sites
- Suitable for both small- and large-scale mapping tasks
- Enables mapping of flood and landslide-prone areas quickly and efficiently
The Outcome
The drone developed through this project provides a practical solution for low-cost, high-resolution geographic mapping in areas where traditional methods fall short. By enabling fast and flexible data collection, it supports disaster risk assessment and planning, particularly in regions vulnerable to natural hazards.
This system allows both experts and non-experts to contribute to local mapping efforts, improving access to reliable geographic information when and where it’s most needed.
