Methods, Maps and Uses of Contours in Surveying
- contour survey services are cost effective and can be customized to suffice the client specifications. Primary objective of conducting these surveys is to identify any noticeable difference in elevation of the existing land. Slopes matching the same height are joined using imaginary lines that are known as contours. Contour map highlights details of the existing land condition. Based on the findings of contour survey, the design team can decide on cutting, filling, widening, and leveling the land..
- Contour Survey Meaning
- Contouring in surveying is the determination of elevation of various points on the land and fixing these points of same horizontal positions in the contour map.
Purposes of Contouring
- A contour map is very useful since it provide valuable information about the land. Contour survey is carried out at the starting of any engineering project such as a road, a railway, a canal, a dam, a building etc.
Methods of Contouring
- 1. Direct method
- 2. Indirect method
1. Direct Method of Contouring
- In this method, the contours to be located are directly traced out in the ground by locating and making a number of points on each contour. These points are then surveyed and plotted on plan and the contours drawn through them. Direct method of contouring is the most accurate but very slow and tedious as a lot of time is wasted in searching points of the same elevation for a contour. Direct Method of Contouring is suitable for small areas and where great accuracy is required.
2. Indirect Method of Contouring
- In Indirect Method of contouring, levels are taken at some selected points and their levels are reduced. Hereby in this method horizontal control is established first and then the levels of those points found. After tracing the points on the plan, reduced levels are marked and contour lines are interpolated between the selected points.
