A negative sight in surveying occurs when the vertical line of sight from the instrument to the target is below the instrument's horizontal axis. This can result in incorrect measurements and lead to inaccuracies in the survey data. Negative sights should be avoided by ensuring that the instrument is properly leveled before taking measurements.

How do you use a surveyors compass?
A surveyor's compass, or a circumferentor is a device used in surveying to measure horizontal angles. It is used by directing the line of sight.
What is the obstacle of chain surveying?
One obstacle in chain surveying is the need for a clear line of sight between survey points, which can be challenging in areas with dense vegetation, buildings, or rough terrain. Additionally, inaccuracies can arise from errors in measurement and recording when using the chain and ranging rods.
Types of surveying in civil engineering?
Plain Surveying Geodetical Surveying
What are general classifications of surveying?
General classifications of surveying include geodetic surveying, plane surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large-scale measurements of the earth's surface, while plane surveying focuses on small-scale measurements on a flat surface. Topographic surveying involves mapping of the land's natural features, cadastral surveying deals with land parcel boundaries, construction surveying is used for building projects, and hydrographic surveying is for mapping bodies of water and their features.
Different types of compass in the field of surveying?
prismatic surveying and surveying compass.

What is the difference between land surveying and geomatics?
geomatics differ with surveying in that it encompasses a broad range of disciplines than surveying,let alone surveying is a discipline under geomatics
What is foresight in surveying?
Foresight in surveying refers to the sighting of a target or point that is ahead of the surveyor's current position. It helps determine the direction of the survey line and aids in maintaining alignment and accuracy during measurements. By focusing on foresights, surveyors ensure precise and reliable data collection for mapping and construction projects.
Explain types of surveying?
Land surveying is mapping out land for land development. Hydrographic surveying is mapping bodies of water. Engineering is a type of surveying that has to do with buildings roads and other man made things.
What is fly levelling?
Fly leveling is a leveling that is done to connect benchmark to the starting point of the survey line. In this leveling only back sight and fore sight readings are taken and auto level is moved strictly on the line joining benchmark and starting point of survey line.
