Higher Surveying: Geodesy, GNSS, and Photogrammetry Fundamentals

Accurate spatial data is the foundation of modern civil engineering, mapping, and environmental planning. If you want to move beyond basic land measurements and understand how large-scale positioning works, mastering advanced surveying methods is essential. This text-only course guides you through the core concepts of higher surveying, from the mathematical shape of the Earth to modern satellite and aerial mapping technologies. You will develop a solid theoretical understanding of how to collect, process, and analyze precise geospatial data for real-world projects. What you'll learn: - Understand the geometric principles of geodesy and coordinate reference systems - Apply Global Navigation Satellite System (GNSS) positioning techniques for high-accuracy mapping - Explain the fundamentals of aerial photogrammetry and drone-based imaging - Analyze digital elevation models and topographic data using modern GIS concepts - Explore the applications of LiDAR and remote sensing in geospatial analysis - Practice calculating survey adjustments and errors through written practical scenarios The course starts with foundational definitions of geodetic datums and coordinate systems before progressing to satellite positioning, aerial photogrammetry, and modern laser scanning techniques. Through clear explanations and step-by-step written exercises, you will learn how to interpret and utilize advanced spatial data. This course is designed for beginners, civil engineering students, and mapping enthusiasts who want to expand their knowledge of geospatial technologies. No advanced surveying experience is required.
