Classify functions - ObjectVision/GeoDMS GitHub Wiki

Classify functions are used to classify the values units of data items to class units. This can be useful, e.g. to present data in a map view.

• classify

• ClassifyEqualCount

• ClassifyEqualInterval

• ClassifyUniqueValues

• ClassifyJenksFisher

• ClassifyNonzeroJenksFisher

• ClassifyNonzeroEqualCount - ClassifyEqualCount on the nonzero values only

• ClassifyNonzeroEqualInterval - ClassifyEqualInterval on the nonzero values only

• ClassifyLogInterval

• weeded_counts - the value-count table these functions classify

Since GeoDMS 20.20.0 each of the classify functions also has a three argument form that takes such a value-count table, calculated once with weeded_counts, instead of the data item itself. See weeded_counts for when that is useful and for how the two forms can differ.
