A runing measurement is the cumulative distance in a straight line from some fixed point of reference.
Running measurements refer to the accumulated distance measured along a linear survey alignment, typically recorded at regular intervals to track progress and location. These measurements help to monitor the actual distance covered and ensure accurate completion of the survey.
Survey poles are long, slender poles typically made of wood or metal that are used by land surveyors to mark specific points on the ground. They often have markings or measurements on them to help with accurate measurements and mapping.
The control line in a land survey is a reference line established through surveying techniques to control the positioning and orientation of survey measurements. It is typically a straight line connecting known points on the ground, used as a reference for conducting accurate measurements and creating an accurate map or plan of the surveyed area.
In chain surveying, a tie line is a straight line connecting two survey stations that helps in checking the accuracy of the survey measurements. It helps to ensure that the survey is properly oriented and that errors can be identified and corrected. Tie lines are important for maintaining the integrity and reliability of the survey data.
An Ordnance Survey Bench Mark is a surveying mark made by the Ordnance Survey to record heights above Ordnance Datum. They are typically found on buildings, bridges, or other structures and are used as reference points for altitude measurements.
In math, a survey typically refers to a set of questions or measurements conducted to gather information about a population or a sample. This data is then analyzed to draw conclusions or make inferences about the larger group.

In chain surveying, fieldwork is limited to taking linear measurements using a chain or tape to establish distances between survey points. This method is commonly used for measuring distances along roads, property boundaries, or other linear features. The accuracy of measurements in chain surveying depends on the precision of the equipment and the skill of the surveyor.
Linear snowball sampling is when the first responent recruits one more person for the survey, who in turn recruits one more person for the survey. Number of people surveyed will increase in a linear manner.Read more: What_is_linear_snowball_sampling
The measurements are taken at right angle to the survey line called perpendicular or right angled offsets. The measurements which are not made at right angles to the survey line are called oblique offsets or tie line offsets.

Think of 2 vessels both running a 3D seismic survey.
This is a non-random sampling technique where the initial respondents to a survey recruit others for a survey. Linear snowball sampling is when the first responent recruits one more person for the survey, who in turn recruits one more person for the survey. Number of people surveyed will increase in a linear manner. The related links provide good discussion of this form of surveying. It is a non-representative sample, but it is an effective means of surveying people with common traits who might otherwise be difficult to find. For example, I want a statistical profile of people that are "hackers" so every hacker I find, I would ask if I could interview his "fellow hackers." See related links.

"Quality terminate" means a respondent was removed from the survey due to not meeting quality standards. "Quota full" means the desired number of respondents for a specific demographic group has been reached, and no more participants from that group are needed.
Centering in theodolite surveying is necessary to ensure accurate measurements by aligning the theodolite's telescope with the survey point. This process helps eliminate errors caused by misalignment, which can lead to inaccurate readings and data. Proper centering ensures that survey points are measured precisely and the survey results are reliable.
