Which description best defines a route survey in land surveying?

• A. Reconnaissance, preliminary survey and location survey for an alignment or linear feature such as a road, railroad, canal, pipeline or utility line
• B. Boundary determination and land ownership mapping
• C. Aerial photography interpretation and mapping
• D. Construction staking along a designed alignment

Answer: (B)

Route surveying is about defining the path for a linear project by gathering information and establishing the precise alignment for design. It involves three progressive steps: reconnaissance to identify feasible routes and general constraints; a preliminary survey to collect detailed topography, constraints, and right‑of‑way considerations; and a location survey to lay out the exact centerline and control needed for final design. The goal is to determine the best route for a road, railroad, canal, pipeline, or utility line, taking into account terrain, existing features, utilities, drainage, and legal or environmental limits, and to establish the data and controls that designers will use.

This focus makes it different from boundary surveys, which determine property lines and ownership; from aerial photography interpretation, which uses imagery to map features; and from construction staking, which places the designed alignment onto the ground during or after the design process.
