The box below illustrates in red attributes from the Corner Point Measured Coordinate entity of the Cadastral Data Content Standard which correspond with data commonly used by surveyors.
Corner Point Measured Coordinate - The Corner Point Measured Coordinate is a X,Y; X,Y,Z,; or Z value for a Corner Point.
X-Coordinate
- This is the X Coordinate value or easting for a coordinate
set.
Domain: numeric
Y-Coordinate
- This is the Y Coordinate value or northing for a coordinate
set.
Domain: numeric
Z-Coordinate
- This is the Z Coordinate value or elevation, which may occur
with or without associated X and Y values.
Domain: numeric
Horizontal Datum
- The horizontal datum is the identification given to the reference
system used for defining the coordinates of points. This definition comes
from the FGDC Digital Geospatial Metadata.
Domain: North American Datum of 1927, North American
Datum of 1983, free text
Vertical Datum
- The vertical datum is the identification given to the reference
system used for defining the elevation of points. This definition comes
from the FGDC Digital Geospatial Metadata. The vertical datum used in this
standard matches the Altitude Datum in the FGDC Digital Geospatial Metadata
Standard, which is the identification given to the surface taken as the
surface of reference from which altitudes are measured.
Domain: National Geodetic Vertical Datum of 1929, North
American Vertical Datum of 1988, free text.
Note: this example and the others
in the crosswalk illustrate correlations between commonly used surveying
information and attributes in the Cadastral Data Content Standard.
However, this example is not meant to cover every possible surveying situation.
Thus you may find, upon reviewing the crosswalk, that you can think of
instances when additional correlations can be found between the Standard
and information surveyors collect.
