Surveying Glossary — Letter S

A coordinated group of satellites orbiting Earth in a planned arrangement to provide continuous global coverage for communications, navigation, or Earth observation.

SBAS ay isang satellite-based augmentation system na nagpapahusay ng accuracy ng GPS positioning para sa surveying at navigation applications.

A numerical multiplier used in surveying to convert ground distances to map distances or to adjust measurements for projection distortions.

The level of detail or precision at which a surveying instrument captures spatial data during scanning operations.

A surveying process that converts 3D laser scan data into a structured Building Information Model for design and construction documentation.

Scene software refers to digital tools and applications used to capture, process, and visualize spatial data from surveying measurements and observations.

Skurkja fotogrametrike mikste, ose sistemi i matjes tre-dimensionale permes fotografive dixhitale te marra nga kamera.

A digital vector data format used in geographic information systems (GIS) to store geometric location and attribute information of geographic features.

An acoustic imaging system that uses sonar transducers mounted on the sides of a survey vessel to create detailed two-dimensional images of the seafloor and underwater features.

A hydrographic surveying instrument that uses a single acoustic beam to measure water depth and seafloor characteristics by transmitting sound waves and recording their echo returns.

Skala peta adalah perbandingan antara jarak pada peta dengan jarak sebenarnya di permukaan bumi yang dinyatakan dalam bentuk rasio, pecahan, atau pernyataan verbal.

A graphical representation of how sound velocity changes with water depth, essential for accurate underwater distance and position measurements in hydrographic surveys.

The ability to distinguish between two closely spaced objects or features in a surveyed area, typically measured as the smallest distance that can be resolved.

The process of marking and establishing precise locations on the ground based on survey plans and design coordinates.

A surveying procedure that establishes and marks specific points on the ground to guide construction projects according to design plans.

A measure of how spread out data points are from the average value in a dataset.

Standarde të përcaktuara që përcaktojnë nivelet e pranueshme të gabimit dhe saktësisë në matjet dhe anketat gjeodezike.

A coordinate system used in surveying that divides the United States into zones with their own map projections to minimize distortion for local surveys.

A surveying method that uses stationary GNSS receivers to determine precise coordinates of fixed points on Earth's surface.

A photogrammetric technique that reconstructs three-dimensional structures from a sequence of two-dimensional images taken from different viewpoints.

A marine geophysical instrument that uses acoustic sound waves to image subsurface geological layers beneath the seafloor for bathymetric and geological surveying.

The process of dividing a larger parcel of land into smaller, legally defined lots for development or sale.

A correction applied to acoustic survey measurements accounting for variations in sound velocity through water columns of different temperatures, salinity, and pressure.

A consistent bias in measurements that causes results to deviate in the same direction from true values.
