Definition of Digital Route Survey
A route survey is a survey conducted across a narrow strip or ribbon-like area to identify and construct a travel and communication system.
Purposes of Digital Route Survey
- Roadways, highways, and railroads.
- Transmission lines for communications, fuel, chemical, water, and electrical needs.
- Canals, waterways, drainage ditches, and sewers.
- View easements, air space easements, and egress easements such as approach routes.
This is done on a larger scale and under different survey conditions (intended to isolate specific subjects). Sea ice conditions, river flood boundaries, and forest fires are made. Also surveys of air routes for specific purposes such as recording centers
The term route survey refers to surveys necessary for the location and construction of lines of transportation or communication that continue across the country for some distance, such as highways, railroads, open-conduit systems, pipelines, and power/telecom lines. Generally, the preliminary survey for this work takes the form of a topographic survey.
The ground-level route survey has been widely used for centuries for mapping remote areas.
In the final stage, the work may consist of the following:
- Locating the centerline, usually marked by stakes at the required interval called Stations.
- Determining elevations along and across the centerline for plotting profile and cross-sections.
- Plotting the profile and cross-sections and fixing the grades.
- Computing the volumes of earthwork and preparing a mass diagram.
- Staking out the extremities for cuts and fills.
- Determining drainage areas to be used in the design of ditches and culverts.
- Laying out structures, such as bridges and culverts.
- Locating right-of-way boundaries, as well as staking out fence lines, if necessary.
