Quality Assurance for Spatial Operations
Specifying the quality of spatial operations requires error determination.
The meaning of “error” depends on the context and application domain.
Potential sources of error in spatial operations include:
- formulation error, approximation error, round-off error, truncation error and other errors associated with implementing the spatial operation.
Errors of this nature should not be confused with errors arising from modeling the true shape of a celestial object (real or virtual) by an approximate shape.
In the SRM, the RDS used to approximate the shape of a celestial object, is assumed to be exact.
- How well a RDS approximates the shape of a celestial object is outside the scope of the SRM.
