GIS Data ReViewer offers several data checks
that can be selected from the drop-down list on
the PLTS GIS Data ReViewer toolbar. These checks
allow you to perform geometric validation as
well as ensure data integrity. All the validation
checks can be applied to an entire feature class
or database, or only the selected set of features.
You can also use a SQL query to determine which
features to use for a particular check.
