VDOP (Vertical Dilution of Precision) is a measure of how satellite geometry affects the accuracy of vertical position measurements in GNSS surveying.
Spatial information represented using geometric primitives such as points, lines, and polygons to define geographic features.
An angle measured from the horizontal plane upward or downward to a distant point or object in surveying and astronomy.
The measurement of vertical angles using the vertical circle of a theodolite or transit instrument to determine elevation angles and heights.
A reference surface used to measure vertical distances and elevations in surveying and mapping.
The difference in elevation values between two different vertical reference systems or datums at the same geographic location.
Näkökenttä on maanmittauksessa käytetty termi, joka kuvaa aluetta, jonka mittauslaite tai silmä voi havaita kerralla ilman, että sitä liikutetaan.
A voxel is a three-dimensional unit of volume in digital space, analogous to a pixel in two-dimensional images, used to represent spatial data in surveying and mapping applications.
A data reduction technique that aggregates 3D volumetric pixels into larger units to decrease computational complexity while preserving spatial information.
VRS ay isang automated na system na gumagamit ng radio signals upang matukoy ang eksaktong lokasyon ng mga puntos sa lupa.
