Surveying Glossary — Letter M
Nyckelbegrepp inom professionell mätning och geospatial teknik.
Automated systems that guide heavy equipment to precise grades and slopes using real-time positioning data and design specifications.
The ratio between distances on a map and corresponding distances on Earth's surface.
A comprehensive measurement and assessment of coastal and ocean environments to map underwater topography, identify hazards, and support navigation.
The average height of the ocean surface calculated over a specific time period, used as the reference datum for measuring elevations.
A specialized surveying methodology that captures precise spatial data of Mechanical, Electrical, and Plumbing systems for integration into Building Information Modeling platforms.
A cylindrical map projection that preserves angles and compass directions, making it useful for navigation but distorting areas, especially near the poles.
Data about data that describes the characteristics, origin, and context of information in a surveying project.
A system of describing land by measuring distances and directions from identifiable physical features or landmarks.
A small reflective prism used in surveying and geodetic measurements to reflect laser signals back to their source for distance calculations.
Mobile mapping is a surveying technique that uses vehicles equipped with sensors and cameras to rapidly collect geospatial data across large areas.
A systematic and continuous measurement process used to track changes in physical features, structures, or environmental conditions over time.
A permanent marker or structure established at a surveying point to mark its location and preserve its position for future reference.
A hydrographic surveying instrument that uses multiple acoustic beams simultaneously to map underwater bathymetry and seafloor characteristics with high resolution and coverage.
A sonar system that emits multiple acoustic beams simultaneously to map the seafloor and detect underwater objects across a wide swath.
The phenomenon where GNSS signals reach a receiver via multiple paths due to reflection off nearby surfaces, causing measurement errors.
Techniques used in surveying to reduce errors caused by signal reflections bouncing off nearby surfaces before reaching the receiver.
Mvs ay isang mahalagang sistema sa surveying na ginagamit upang masukat at magrehistro ng mga spatial data sa pamamagitan ng modernong teknolohiya.
