A group of satellites working together in coordinated orbits to provide continuous global coverage and services.
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 distances measured on maps, plans, or in field surveys to their true ground dimensions or vice versa.
The level of detail or precision at which a scanner captures spatial data, typically measured in dots per inch (DPI) or points per unit distance.
The process of converting laser scan or photogrammetry data into Building Information Models for construction and facility management.
Software designed to create, manage, and render virtual 3D environments and digital scenes for various applications.
Structore from Motion (SfM) est une teknik imaging 3D ki photograft banyak-banyak dari obyek ambil dari angle berbeda para konstruk model 3D otomatis.
A digital file format used in Geographic Information Systems (GIS) to store geometric location and attribute information of geographic features.
A hydrographic surveying instrument that uses acoustic signals to create detailed two-dimensional images of underwater surfaces and features by transmitting sonar beams perpendicular to the vessel's direction of travel.
A hydrographic surveying instrument that emits a single acoustic beam to measure water depth by calculating the time delay of reflected sound waves from the seafloor.
A measurement of how sound speed varies with water depth, essential for accurate underwater positioning and bathymetric surveying.
The ability of a surveying instrument or system to distinguish between closely spaced objects or features on the Earth's surface.
The process of marking and establishing precise locations on the ground according to surveyed coordinates and design plans.
A surveying process that involves marking and locating specific points on the ground according to predetermined design coordinates and plans.
A measure of how spread out data points are from the average value in a dataset.
A system of map projections used in the United States that divides each state into zones with unique coordinate grids for accurate surveying and mapping.
A surveying technique that uses Global Navigation Satellite System receivers positioned stationary at survey points to determine precise three-dimensional coordinates.
A photogrammetric technique that reconstructs three-dimensional structures from a sequence of two-dimensional images taken from different viewpoints.
A geophysical instrument that uses acoustic waves to image sediment layers and subsurface geological structures beneath water bodies.
The division of a parcel of land into two or more smaller lots for purposes of development, sale, or transfer.
A senior surveying professional responsible for overseeing survey operations, quality control, and team coordination in major surveying projects.
A hydrographic surveying correction applied to acoustic depth measurements that accounts for variations in sound velocity through water layers of different temperatures, salinity, and pressure.
Consistent measurement errors that occur in the same direction and magnitude, caused by instrument calibration issues, environmental factors, or procedural flaws.
