GIS Lounge runs a short introduction to spatial data quality. A topic recently covered. From the article's introduction: "Data created from different channels with different techniques can have discrepancies in terms of resolution, orientation and displacements. Data quality is a pillar in any GIS implementation and application as reliable data are indispensable to allow the user obtaining meaningful results. Spatial Data quality can be categorized into Data completeness, Data Precision, Data accuracy and Data Consistency."

1Spatial is has announced the creation and provision of a new Data Quality Library, and is inviting contributions from others in the spatial data industry. From the www.geocomm.com website: "As a result of working in the geospatial arena for almost 30 years with a variety of prestigious and high profile customer and partner organisations, 1Spatial has identified the need for greater information access, sharing and awareness relating to spatial data quality. The library will house a collection of material and links relating to spatial data quality produced by 1Spatial, industry colleagues, independent analysts and academics, providing a free, centralised resource for all spatial data users. There is currently a vast amount of information relating to this topic available, but no single repository for industry access and sharing." Learn more below.
