The Sampling check generates a set of features from one or more
layers that you can step through to visually inspect. The sample
is generated from the feature classes you choose to include
based on what is loaded in the map. You can also assign weights
to the feature classes, which increases or decreases the number
of features for the feature classes that are included in the
sample. A value of 1 is the highest weight; 5 is the lowest. The
sample is calculated based on one of the following methods: - A
fixed number of features - A percentage of all the features in
the specified extent - A number derived from a calculation based
on the confidence level, margin of error, and acceptance level -
A polygon grid that is loaded in the map or from a geodatabase
You can choose to run this check on any of the extents that are
usually available with checks, such as the selection set,
current extent, or the full database. Once you have defined the
criteria for the check, you can configure the notes and a
severity rating.
