Slice and Compare Surveys By Attributes

Objective

The Slice and Compare Surveys by Attribute function is used to compare Rock Art Class attributes from multiple surveys and highlight those attributes which have elements common to multiple surveys or unique to a single survey. One usage of this function is to compare rock art sites that are thought to have been occupied by the same cultures and verify there are no unexpected differences in rock art styles.

This function is similar to CompareSurveysByAttributes but has an additional feature. It splits the elements within a survey by the attributes of a selected attribute set. The intended usage is to compare older/younger elements within a survey. To start, a list of all exclusive choice attribute sets are displayed. Choose any set, the usual choice is General.Age.

A second usage of this function is to compare two sites thought to have been occupied by different cultures and identify differences in rock art styles.
