Photogrammetry vs. traditional surveying: a comparative study

Traditional surveying has been the cornerstone of land measurement and mapping for centuries. It involves the use of tools such as theodolites, levels, and total stations to measure angles, distances, and elevations. This method requires a significant amount of manual labor and time, as surveyors must physically traverse the terrain to gather data point by point. Photogrammetry, on the other hand, is a modern surveying technique that uses photographs to measure and map features on the Earth's surface. By taking overlapping images from different angles, photogrammetry software can create

Historical buildings are not just structures; they are tangible links to our past, telling stories of different eras, cultures, and communities. Preserving them is crucial for educational purposes, cultural identity, and economic development through tourism. However, the delicate nature of these buildings poses unique challenges in their preservation. Laser scanning, also known as LiDAR (Light Detection and Ranging), is a cutting-edge technology that captures detailed 3D data of objects and environments. It has revolutionized the way we document, analyze, and preserve historical structures.
