ThreeDimensionalSurfaceType
urn:aero:airm:1.0.0:LogicalModel:DataTypes:GeometryTypes:ThreeDimensionalSurfaceType
Derived from GM_Surface and extended to include properties that represent the vertical position (elevation, datum, accuracy).
Properties | Definition | Type |
---|---|---|
elevation | The vertical distance of a point or a level, on or affixed to the surface of the earth, measured from mean sea level. | ValAltitudeType |
verticalResolution | A distance corresponding to the number of units or digits to which a measured or calculated value is expressed and used. | ValDistanceType |
verticalDatum | The set of reference points or a mathematical model of the Earth's surface (a datum) against which vertical position measurements are made as basis for measuring elevations. | CodeVerticalDatumType |
verticalConfidenceLevel | A statistical measure of the estimated confidence with which the data captured met its required accuracy. A required confidence level of 90% indicates that 90% of the measured point(s) should meet their respective accuracy requirements. |
Integer |
verticalAccuracy | The difference between the recorded elevation of an entity and its true elevation referenced to the same vertical datum expressed as a linear error at 95 percent probability. | ValDistanceType |
horizontalResolution | A distance corresponding to the number of units or digits to which a measured or calculated value is expressed and used. | ValDistanceType |
horizontalConfidenceLevel | A statistical measure of the estimated confidence with which the data captured met its required accuracy. A required confidence level of 90% indicates that 90% of the measured point(s) should meet their respective accuracy requirements. |
Integer |
horizontalAccuracy | The difference between the recorded horizontal coordinates of an entity and its true position referenced to the same geodetic datum expressed as a circular error at 95 percent probability. | ValDistanceType |
geoidUndulation | The distance of the geoid above (positive) or below (negative) the mathematical reference ellipsoid at the location of the surface. | ValDistanceType |
