Scale Factor

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

Scan to BIM

Процесс преобразования трёхмерных облаков точек, полученных лазерным сканированием, в информационные модели зданий.

Scene Software

A specialized computer application designed to create, manage, and visualize complex spatial environments and three-dimensional landscapes for surveying and mapping purposes.

Spatial Resolution

The ability of a surveying instrument or system to distinguish between two closely spaced points or features on the Earth's surface.

Stakeout

The process of marking and establishing precise points on the ground according to surveyed locations and design plans.

stakeout survey

A surveying process of marking and establishing precise locations on the ground according to predetermined coordinates and design plans.

standard deviation

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

State Plane Coordinates

A coordinate system used in surveying and mapping that divides the United States into zones with unique projections to minimize distortion over specific geographic areas.

Static GNSS

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

Structure from Motion

A computational technique that reconstructs three-dimensional models of objects and environments from a sequence of two-dimensional images taken from different viewpoints.

Subdivision

The process of dividing a tract of land into smaller parcels for development or sale.

systematic error

A consistent, predictable error that occurs in the same direction and magnitude during repeated measurements in surveying.
