Title:
*
Change Requests for WCS to Support Error Propagation
Source:
*
OWS-6 SWE Georeferenceable Imagery thread
Work item code:
Category:
*
Reason for
change:
*
1. The metadata associated with a WCS are not specifically fit for the purpose of error propagation. They need to be profiled and extended to have named roles to indicate the source error and the newly-introduced error.
2. For the introduced error, a WCS may have different coverage processing, see subclause 10.3.3. Depending on the implementation of the WCS, the order of processing may result in introduction of
different errors. Depending on the user’s request, the processing may differ and therefore, the resulted error is different. This should be explicitly described in the output coverage.
Summary of
change:
*
Add the error propagation support in the WCS. Specifically, the following operations and responses are affected.
1. DescribeCoverage
2. Example clauses of requests and responses
3. GetCoverage
Consequences if
not approved:
Clauses affected:
*
1. Subclause 9.3.1.1 2. Subclause 9.5 3. Subclause 10.3.9
