Note: this example and the others in the crosswalk illustrate correlations between commonly used surveying information and attributes in the Cadastral Data Content Standard.  However, this example is not meant to cover every possible surveying situation.  Thus you may find, upon reviewing the crosswalk, that you can think of instances when additional correlations can be found between the Standard and information surveyors collect.
