Automated quality controls with FME Anna Halvarsson and Johan Esko Metria

. How do I

know if the data meet my quality

demands?

Definition of quality

“The degree to which a set of inherent characteristics fulfills requirements”

ISO 9000:2000

Best quality?

Swedish Technology Journal

“Short wheelbase and minimal overhang at the front and

rear, combined with high ground clearance makes it extremely well suited to continue the drive where the road ends. Indeed the Niva outperform the Porsche Cayenne, which in comparison is clumsy as an elephant with a backpack in a supermarket”.

(Teknikens värld, 2006)

Comment: “If it is the terrain capabilities that is evaluated, the Niva

fulfils the quality requirements better than the Porsche.”

Best quality?

Which one of these view services delivers data with the highest positional accuracy?

How to manage quality in my SDI?

Data QC service - Pilot project

Objectives:

1. The QC service shall in a standardized and traceable way describe the quality of data

2. The QC service shall automatically perform the controls

3. The QC process shall be the link between the EPA:s manuals and the result published by the data host.

Applies to both cars and bikes

Finally

• During 2014 the validation service will be launched in version 1.0.

• In Sweden a number of agencies have started to work with Product specifications and quality controls according to ISO standards.

• Private companies are also showing much more interest in data quality issues than they did a couple of years ago.
