Empty Geometry

The Empty Geometry quality control (QC Quality Control) check identifies features in a spatial feature class that contain an attribute Nonspatial information about a geographic feature in a GIS, usually stored in a table and linked to the feature by a unique identifier. For example, attributes of a river might include its name, length, and sediment load at a gauging station. record but no geometry.

Note: 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 supports empty geometry and complex geometry upon upload; however, empty geometry records are not transferred into the target dataset and complex geometry is simplified. As a result, Empty Geometry is only allowed to run on Source datasets. Please note this QC check does not modify data.

To run this check, a feature is required.

Configurations for QC check parameters contain filters to prevent selecting incompatible field types.

The following parameters can be specifically configured for the Empty Geometry QC check.

  • Run On: Non-configurable. This QC check inspects the source dataset.

  • Severity: Sets the importance level of this QC check’s fallouts. Critical fallouts prevent export package outputs but will still provide fallouts.

  • Layer Name: The name of the layer this QC check should inspect.

  • Reporting Unique ID: A unique identifier in the layer that can be used to uniquely identify a singular feature.

The following information is included for this QC check's fallout output.

  • QC check name
  • Description of the QC check
  • Number of fallouts detected when fallouts exceed GIS Data Hub reporting thresholds
  • Feature class where the fallout appears
  • Extended information providing more details about the fallout

This example shows possible error messages that may be received when a record fails the Empty Geometry QC check.
