Which surveying method is used for the centerline and right-of-way of transportation lines?

Route surveying is specifically used for determining the centerline and right-of-way of transportation lines, such as roads, highways, and railroads. This method involves the detailed examination and mapping of the proposed alignment of a transportation route, considering various factors such as topography, existing land usage, and environmental impact. The objective is to establish a clear and precise path for construction while ensuring compliance with legal and regulatory requirements.

In the context of transportation lines, route surveying provides valuable information that guides engineers and planners in designing a safe and efficient route. It assists in determining necessary adjustments for elevation changes, drainage issues, and the integration of the route with existing infrastructure. This focus on alignment and right-of-way makes route surveying distinct and essential for transportation projects.

The other methods listed, while relevant in broader surveying contexts, do not specifically address the requirements of determining transportation line alignments and right-of-way. For example, land surveying generally encompasses a wider array of property boundaries and land features rather than focusing solely on transportation routes.
