Βασικοί όροι στη δημοσιογραφική τοπογραφία και τη γεωχωρική τεχνολογία.
A surveying technique that provides precise elevation and positioning data to automated construction machinery for real-time grade and alignment control during earthwork operations.
A mathematical method of representing the three-dimensional Earth's curved surface on a two-dimensional flat map or coordinate system.
Map scale is the ratio between distances on a map and their corresponding distances on the Earth's surface, expressed as a fraction, ratio, or graphic representation.
Marine survey is the systematic measurement and mapping of underwater and coastal features, including seabed bathymetry, obstructions, and maritime boundaries for navigation, construction, and resource management.
Mean Sea Level (MSL) is the average height of the sea surface across all tidal cycles, used as the primary vertical reference datum for surveying and elevation measurements worldwide.
A cylindrical map projection that represents the Earth's surface with constant bearing lines (rhumb lines) appearing as straight lines, widely used in marine navigation and modern web mapping applications.
A method of describing land boundaries using natural and artificial landmarks, distances, and directions rather than coordinates or geometric shapes.
MicroSurvey FieldGenius is a comprehensive field data collection and surveying software platform designed for surveying professionals using total stations, GNSS receivers, and other surveying instruments.
A compact optical reflector used with total stations and laser theodolites to measure distances and establish precise positioning in surveying operations.
A mobile mapping system is an integrated platform combining GNSS, IMU, and imaging sensors mounted on vehicles to rapidly collect geospatial data for surveying and mapping applications.
Multibeam sonar is a hydrographic surveying technology that emits multiple acoustic beams simultaneously to create detailed bathymetric maps of underwater terrain.
Multipath error mitigation refers to techniques and technologies used to reduce signal reflections and their distortive effects on surveying measurements in GNSS and other positioning systems.
Multi-View Stereo (MVS) is a 3D reconstruction technique that uses multiple overlapping photographs from different viewpoints to create dense point clouds and detailed 3D models for surveying and mapping applications.
