• Applying QA/QC Procedures to Quantitatively Measure the Quality of NCDOT GIS Data

    NCDOT Research Project Number: 2014-02

Executive Summary

  • The current state of the NCDOT Roads GIS database is unknown. While adequate metadata does exist to explain various descriptive, structural and administrative information about the data, it is very general at best and does not include specific revisions and updates that have occurred throughout the life of the data. As a result, a need exists to explore various dimensions of data quality within this robust database. While verifying each of the individual features and accompanying attributes is an impossibility within the scope of this research project, this research looked to explore various QA/QC (Quality Assurance/Quality Control) assessment techniques and integrated procedures within the framework of accepted QA/QC standards. This goal of this research project was to explore the integrity of the NCDOT GIS database at various scales. A result of this research was to give the NCDOT a snapshot of their database and if it is sub-standard, a direction to dictate data development or re-development efforts as part of later in-house or contract work.
