What is Surveying?
Surveying is the process of analyzing and recording the characteristics of a land area span to help design a plan or map for construction.
Total Station is the currently preferred Surveying equipment in the industry. Find out
What is a Total Station? here and about Survey camp using Total Station workshop here.
Categories of Surveying are:
Surveys are carried out on a large scale with the help of control networks spanning over long distances.
Surveys are carried out to define land ownership and boundaries.
Surveys are carried out to determine land structure along with variation in land heights.
As Built Surveying:
Surveys are carried out after completion of a construction project to check variance from proposed design.
Photogrammetry (Aerial Surveying):
Surveys are carried out by taking photographs from elevated ground stations.
LiDAR (Aerial Surveying):
Surveys are carried out using remote sensors and light reflected by lasers to measure distances.
Fundamental techniques used for Surveying are:
In this technique numerous triangles are inter-connected and overlapped to measure angles from a surveying station.
It follows the same technique as in Triangulation with additional use of Electronic Distance Meter (EDM).
In this technique multiple lines of pre-measured lengths are inter-connected to measure angles and distances.
In this technique the difference in heights in a terrain are measured with the help of graduated rods.
In this technique radiating lines are drawn from a focal point to defined boundaries converted to a small scale surveying sheet.
Surveying finds multiple industrial applications across various domains. It is an integral part of Civil Engineering Discipline.
