EMS¶

The wiki for this project contains the following information:

1. Scope of the Edge Matching Service
2. User documentation for the Edge Matching Service
3. Developer documentation for the Edge Matching Service

This is the current development milestone plan:

M1:Released, 15.05.2009

• Test suite to ensure high quality edge matching and to show what quality of edge matching can be achieved with the JCS (Java Conflation Suite).
• Added DatasetCleaning operation
• Find stable GML implementation
• Revisions and improvements supporting GML 2.1.2

M2:Released, 30.06.2009

• CoverageAligner implementation supporting "align-to-reference" mode
• CoverageAligner implementation supporting "distribute-errors" mode

M3:Released, 31.07.2009

• Added Lineage documentation to the metadata of the processed data sets
• Automatic decission on align-to-reference or distribute-errors mode given the scale or the positional accuracy.
• Hosting server offering the EMS

M4:Released, 30.10.2009

• Coverage Aligner bug in align-to-reference mode fixed -no result changes after align-to-reference processing.
• Fixed bug obtaining data inputs.
• Improvement of the Coverage Aligner process by adding a new algorithm for a better performance aligning borders.
• Calculate the maximum distance and average distance points were moved during the EMS process.
• Shapefile format supported as input.

Long Term Milestones

• Implementation of the GeometryTranslation operation
• Readers for other supported input formats (GML 3.1)
• Extend the CoverageAligner and the GeometryTranslation operations in order to support n-candidate data sets.
