Bounds Checking
Coordinate transformations may only be valid for prescribed regions
Both input and output should be checked for validity
For many coordinate frameworks, the mathematical formulation may exist everywhere even though the results may be nonsensical for some regions
Determining acceptable bounds requires an examination of distortion effects and, in some cases, computational accuracy
This is an emerging issue for SRM standardization efforts
The problem is multi-faceted:
- What are the acceptable bounds?
- For which applications?
- Who determines them?
