Correction: What is hydrographic datum? not "hydrography"
sorry but i don't think there is something as datum
Datum is singular. Data or datums is plural.
According to ASME Y14.5, a primary dimensioning datum requires at least 3 points of contact to establish the datum plane. Two points of contact are required for the secondary datum and 1 point of contact is required for the tertiary datum.
The datum is supported by thorough research.
The plural form for the singular noun datum is data.
Omne Datum Optimum was created in 1139.
Datum surfaces are reference surfaces used in engineering and manufacturing to establish a common point for measurements and alignments. They provide a consistent and uniform starting point for design and quality control processes. Examples include planes, lines, and points from which other measurements are made.
A datum peg in construction is a fixed reference point used to establish a baseline for measurements and elevations on a building site. It is typically a stake or marker placed at a known height, which helps ensure consistency in leveling and alignment throughout the construction process. Datum pegs are crucial for accurate site layout, preventing errors in the positioning of structures and ensuring compliance with design specifications.
To select a suitable datum, consider a stable reference point on the workpiece or surface. Mark the datum clearly and securely. When marking out, ensure all measurements and reference points are taken from this datum to maintain accuracy and consistency. Working from a different datum can lead to incorrect measurements, misalignments, and errors in the final product. It is crucial to avoid this by consistently using the established datum.
When utilizing the DAGR, the field that automatically displays the waypoint datum is the "Dat" field, which stands for datum. The datum represents the reference point used to define the location coordinates of the waypoint.
