Geodetic surveying is focused on measuring large areas of the Earth's surface while taking into consideration the curvature of the Earth. This type of surveying utilizes precise mathematical models and measurements to account for the Earth's shape and gravitational variations. By addressing the curvature, geodetic surveying ensures that the measurements are accurate over extensive regions, making it essential for tasks such as national mapping, boundary demarcation, and large infrastructure projects.

In contrast, the other options typically involve surveying methods tailored to smaller or more localized measurements. For very small areas, traditional surveying methods are often sufficient without the need for geodetic considerations. Areas affected by volcanic activity might require specialized geological assessments rather than a focus on geodetic principles. Urban development projects usually involve site-specific surveying for construction and planning, which is not based on the broader geodetic framework required for larger scales. Thus, the emphasis on Earth's curvature in geodetic surveying is what distinguishes its applicability to expansive areas.
