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

To close travers error calculation, use the formula 2n-4.

• To close travers error calculation, substitute the value of n into the formula 2n-4.

• For example, if n=3, the calculation would be 2(3)-4 = 6-4 = 2.

The tolerance of subgrade top refers to the acceptable deviation from the specified elevation of the subgrade surface.

• Tolerance of subgrade top is typically specified in project plans or specifications.

• It is important to measure and ensure that the subgrade top meets the specified tolerance to ensure proper construction of the pavement layers.

• For example, a typical tolerance for subgrade top may be +/- 0.1 feet from the specified elevation.

Level work involves using a level instrument to determine the elevation of points on the ground.

• Set up the level instrument at a known benchmark point

• Take readings at various points to determine their elevations

• Use the leveling rod to measure the height difference between the instrument and the ground

• Calculate the elevation of each point based on the readings

• Ensure the instrument is properly calibrated for accurate results

Some software related to GIS surveying include ArcGIS, QGIS, and AutoCAD Civil 3D.

There are no 'leescount' in an auto level. It seems like a typo or misunderstanding of terminology.

• There is no concept of 'leescount' in auto level surveying equipment.

• It is possible that the interviewer meant to ask about something else related to auto levels.

• It is important to clarify any confusion or misunderstanding with the interviewer.

Camber is the curvature of the road surface while gradient is the slope of the road surface.

• Camber refers to the curvature of the road surface, typically used to aid in water drainage.

• Gradient refers to the slope of the road surface, indicating the rate of incline or decline.

• Camber is measured in percentage or ratio, while gradient is measured in degrees or percentage.

• Example: A road with a positive camber will slope slightly towards the center, while a road with a positive g...read more
