Data Quality DWG

The mission of the DQ DWG to establish a forum for describing an interoperable framework or model for OGC Quality Assurance measures and Web Services to enable access and sharing of high quality geospatial information, improve data analysis and ultimately influence policy decisions.

The WG will attempt to define a framework and a grammar for the certification and communication of spatial DQ. This method to describe and communicate data quality measures will reference, but not be limited by, a number of categories:

  • Accuracy 
    • Positional accuracy
    • Temporal accuracy
    • Thematic accuracy
  • Completeness
  • Consistency and Integrity
  • Definition (for semantic interoperability)
  • Language
  • Projection
  • Scale 

Reference shall be made to the standards defined in ISO 19113, 19114, and 19138. ISO 19115 meta data standards are relevant in the storage of such measures and quality descriptors.
