QC Checks

GIS Geographic Information System. A computer application that involves storing and manipulating electronic maps and related data. Also, mapping software combining spatial information about where places and events are located with data attributes describing those places and events. Data Hub can perform quality control (QC Quality Control) checks on submitted GIS data to ensure addresses are synchronized, roads are connected, standards are met, errors are identified, and more. When executed, the application begins the process of running a series of quality control checks to ensure current, accurate data.

There are many QC checks that may be processed to ensure data quality. The following is a list of available QC check categories and links to the individual QC checks that may be processed depending on your specific needs.

These checks find errors at the feature level for attributes such as field comparisons, duplicate values, and unique IDs. See Attribute QC Checks.

These checks find errors in the data's geometry such as identifying gaps or overlaps in polygons or roads that are not split at boundaries. See Geometry QC Checks.

This check validates and modifies flagged information. See Ingest Validation QC Checks.

These checks find errors where the address data is mismatched and does not accurately synchronize some or all of the following: full street name, address number, address suffix, zone parity, block, and or address range. See Synchronization QC Checks.
