Coherent Market Insights Interview Questions and Answers

Utilize the TBM efficiently by strategically connecting instruments

• Prioritize critical instruments for connection first

• Consider using multiplexers to connect multiple instruments to one TBM

• Implement a communication protocol to ensure smooth data transfer

• Ensure proper calibration and testing of connected instruments

• Have a backup plan in case of TBM failure

To check errors in a Total Station, perform a calibration check and ensure proper leveling and alignment.

• Perform a calibration check by measuring a known distance and comparing it to the Total Station's measurement.

• Ensure the Total Station is properly leveled and aligned before taking measurements.

• Check for any physical damage or obstructions that may affect the accuracy of the Total Station.

• Verify that the instrument is set to the correct units and coordinate system for the ...read more

Data can be imported in AutoCad using the 'Data Extraction' tool.

• Open the drawing in AutoCad

• Go to the 'Insert' tab and click on 'Data Extraction'

• Select the objects from which you want to extract data

Coordinates are sets of numbers used to determine the position of a point in a space or on a map.

• Coordinates consist of latitude and longitude values

• Latitude measures how far north or south a point is from the equator

• Longitude measures how far east or west a point is from the Prime Meridian

• Coordinates are commonly used in GPS systems to pinpoint locations

Transverse survey involves measuring distances and angles to determine the position of points on the ground.

• Set up the theodolite at a known point and measure a back sight to a benchmark.

• Take foresight readings to the points to be surveyed, recording both the horizontal and vertical angles.

• Measure the distances using a tape or EDM.

• Calculate the coordinates of the points using trigonometry and the measured angles and distances.

• Check the accuracy of the survey by closing the tr...read more
