Route surveying lays out transportation systems with the four basic operations.
1. Reconnaissance survey - done to familiarize the engineer on the terrain involved. This survey is for collecting information about the topography of the area in order to select a narrow band along which the route can be located.
2. Preliminary survey - the survey where accurate control traverse is conducted to identify the narrow strip with its longitudinal and cross sections.
3. Location survey - prepares papers for location of route and transfers the alignment on site.
4. Construction survey - Survey involved in setting out details of the route on ground.
Any transport system (railroads, highways, waterways, electric transmission lines, pipelines, and linear transportation or utility routes) can be drawn and aligned with these basic
operations.
