Data Quality

From OSGeo

For now this page is to discuss a proposal for a short project (4-7 months) looking at data quality approaches to collaborative online sources of information. This is something that could be an interesting fit for the geospatial strand of JISC funding call 15/10 on infrastructures for education and research.


  • INSPIRE does not mandate quality standards but Joint Research Commission recognises that not to consider quality, is an oversight.
  • The ISO standards regarding quality of geographic information are oriented towards quality assurance in the data production process
  • This means a lack of focus on the value of data quality information from the end-user's perspective - what problems are we helping to solve by publishing data quality information?
  • For example, OS Research has done extensive work on a "vernacular gazetteer" of shapes for social names, but data quality concerns prohibit its release, even for research.
  • Geodata world has its domain specific problems, can benefit from looking at lighter weight /

differently conceived quality approaches from other domains.

  • The aim should be to encourage and support the publication of more data of variable, knowably unknown quality.
  • Quality currently looks like a niche issue. New developments in data sharing over the internet will raise priority for machine-reusable descriptions of data quality (distributed databases; multiple copies of the same resource unsynchronised, or variably edited; more collaborative mapping projects along lines of OSM and OpenAddresses; lossy or transient datastores; linked data pollution)

Fit for 15/10?

See the briefing paper on the JISC geospatial strand for more context - up to 9 months duration between Feb and Dec 2011.

  • Briefing emphasises infrastructure development, re-use of tools and services, both those directly supported by JISC and others popular on the web


  • Starting with Nothing
  • Attestation
  • Edit-time quality reporting
