Automation of Civil Engineering Surveying with Distance Measuring Sensor and Wireless Technology

Objectives: To automate the surveying practices, which are done manually and are not highly accurate, by the assemblage of the distance measuring sensor, wireless technology, and computerized data processing.

Method: With the help of distance measuring sensor, various observations are obtained from the field based on the required objectives (area measurement, fly leveling etc), the data is transmitted from the field to the computer with the help of wireless technology and the data obtained is processed with the computer software to get the desired results.

Findings: This method completely eliminates the use of the equipment which is in practice and it overcomes various drawbacks in conventional methods such as poor accuracy, the necessity of skilled labors, less automation, no compaction in equipment etc. With this proposed idea/technique, all the methodology for various surveying practices have been proposed and a sample of fly leveling (taking a small ramp) has been carried out with this technique.

Applications: The main applications in civil engineering surveying are Measurement of horizontal distance, Measurement of vertical elevation, Measurement of area, Fly leveling, Grid Contouring, and Radial Contouring. Apart from these applications, it also includes secondary applications, such as using the sensor and add-on equipment, it can also be applied to ensure the verticality of the building, checking the RL of the roads, De-alignment in Railway tracks, Getting the profile of the bridges.
