Given the significant role that photogrammetry plays across a wide range of applications, both in engineering and beyond, and the invaluable services it provides, whether directly experienced or indirectly beneficial. There is nothing more worthwhile or beneficial than presenting this book to esteemed readers, whether they are passionate about photogrammetry or among our cherished students. This book comprises eight chapters. The first introduces the science of photogrammetry, definition, historical, branches, applications, units. The second delves into lenses and cameras, their types and interconnections. The third focuses on aerial photogrammetry, different types of aerial photos, design of photographic projects, and the geometric relationships, and their corresponding real-world representations. The forth provides three-dimensional vision, related instruments, techniques, and methods. The fifth offers a concise overview of oblique aerial photography and methods for calculating ground point coordinates. The sixth shifts to ground photogrammetry, coordinates can be derived from terrestrial photograph. The seventh includes solved examples, the eighth presents general exercises.
