Overview of Photogrammetry and Aerial Surveying
Photogrammetry is the science of obtaining reliable measurements and creating maps by recording, measuring, and interpreting photographic images. Aerial surveying takes this process to the skies, capturing images from aircraft or drones to produce detailed maps and models of the Earth's surface. Mapping, in this context, involves representing geographical data visually, often as two-dimensional or three-dimensional models that bring landscapes to life.
A Brief History and the Evolution of Drone Technology
Photogrammetry dates back to the early 19th century when aerial photography was pioneered using balloons and kites. Over the 20th century, aerial surveying advanced significantly with the introduction of manned aircraft. Drones have revolutionized the field, offering unprecedented accessibility, lower costs, and incredible flexibility. Equipped with advanced cameras, modern drones deliver high-resolution imagery and high-quality data, making aerial surveying more approachable for professionals and enthusiasts alike.
Who is This Guidebook For?
This book is designed for beginners, new drone pilots, and aspiring mappers who want to build a solid foundation in aerial surveying and photogrammetry. It's also ideal for those seeking to refresh their knowledge in this field. While comprehensive in scope, the guide provides a "big picture" view without overwhelming readers with the intricate details of this complex technology. Instead, it prepares users for deeper exploration as they become familiar with hardware and associated software workflows. Rather than diving too quickly into technical minutiae, this guide offers an approachable introduction, avoiding the common pitfall of scaring off new learners. Pacing the learning process ensures aspiring drone pilots and photogrammetrists gain confidence without feeling overwhelmed.
Why Focus on the DJI Mavic Series?
While the guide is relevant to nearly all commercially available drones, it emphasizes the DJI Mavic Series. This series was chosen for its ease of use, robust software support, and widespread popularity. The Mavic drones are an excellent starting point for beginners, providing the tools and reliability needed to succeed in aerial surveying and mapping.
