Martin Desruisseaux created SIS-335:
---------------------------------------
Summary: CRS.findOperation(…) sometime slow
Key: SIS-335
URL: https://issues.apache.org/jira/browse/SIS-335
Project: Spatial Information Systems
Issue Type: Bug
Components: Referencing
Affects Versions: 0.7
Reporter: Martin Desruisseaux
Assignee: Martin Desruisseaux
Fix For: 0.8
Execution of {{CRS.findOperation(sourceCRS, targetCRS, areaOfInterest)}} is
slow when:
* A connection to the EPSG geodetic dataset is available (which is recommended)
* the given CRS have no EPSG identifiers, or their identifiers are wrong
In such case, {{IdentifiedObjectFinder}} search the right EPSG code for the
given CRS by scanning the EPSG database. Some conditions are put in the SQL
{{WHERE}} clause for reducing the amount of CRS to scan, but in Apache SIS 0.7
those conditions are not restrictive enough, resulting in way too many CRS
being scanned.
