Almarai Land Surveyor Interview Questions and Answers for Experienced

The least count of a total station is the smallest measurement that can be accurately read or recorded by the instrument.

• The least count is determined by the precision of the instrument's internal components.

• It is typically expressed in units of distance, such as millimeters or seconds of arc.

• For example, if the least count of a total station is 5mm, it means that the instrument can measure distances accurately to the ...read more

The height of a mini prism varies depending on the manufacturer and model.

• Mini prisms are used in surveying to measure distances and angles.

• The height of a mini prism is typically between 25mm to 50mm.

• The height of a mini prism can affect the accuracy of the surveying measurements.

• It is important to use the correct height of mini prism for the specific surveying task.

• Manufacturers usually provide the height of their mi

The least count of an auto level is the smallest measurement that can be read on the instrument.

• The least count is determined by the size of the divisions on the instrument's scale.

• It is usually expressed in millimeters or fractions of an inch.

• For example, if the least count is 0.5 mm, the instrument can measure differences in elevation of 0.5 mm or greater.

• The least count can vary depending on the make and model of th

Laying out coordinates involves marking specific points on the ground based on their x, y, and sometimes z values.

• Use a total station or GPS device to accurately measure and record coordinates

• Mark points with stakes, flags, or paint for future reference

• Ensure coordinates are recorded in the correct datum and projection for accurate mapping

Auto level is a surveying instrument used to measure height differences in the field.

• Auto level uses a compensator to ensure accurate readings even on uneven terrain.

• It is commonly used in construction, land development, and road building projects.

• The instrument is set up on a tripod and the surveyor looks through the eyepiece to read the height difference on a graduated staff.

• Auto levels are preferred for their ease o...read more

Trivers for target point refers to the process of using trigonometry to calculate the coordinates of a specific point on a surveying site.

• Trivers formula involves using angles and distances to calculate the coordinates of a target point.

• It is essential for accurate land surveying and mapping.

• Example: If you have the angle and distance measurements from two known points, you can use Trivers formula to calculate the coor

A point for set out is a reference point used by surveyors to mark the location of specific points on a site.

• Set out points are typically marked with stakes, nails, or paint on the ground.

• These points are used to guide construction workers in accurately placing structures or boundaries.

• Surveyors use measurements and calculations to determine the exact coordinates of set out points.
