What does softcopy photogrammetry primarily utilize?

Softcopy photogrammetry primarily utilizes digital manipulation of spatial geometry. This process involves using computer software to analyze photographs and extract measurements or create three-dimensional models. By leveraging digital tools, it enables more accurate and efficient representation of the spatial relationships present in the captured imagery.

In the context of softcopy photogrammetry, digital manipulation encompasses several tasks, including image rectification, feature extraction, and automated point matching, which are facilitated by sophisticated algorithms and processing capabilities that are inherent in modern computing technology. This stands in contrast to traditional methods, which might rely on manual calculations, film-based imagery, or physical surveying equipment. Such advancements in softcopy techniques allow for enhanced precision and ease in handling complex datasets, making it a critical aspect of modern surveying and mapping practices.
