DB Table Name taxonAlt
Table Taxon Alt
Notes This table shows alternate taxa that are to be grouped for a taxonInterpretation.
Description When this table is used, the taxonInterpretation that is referenced here is interpreting the taxonObservation as the combination of all plantConcepts referenced in this table with the same taxonInterpretation_ID. TaxonInterpretation.groupType shows what type of group this is (one of, union, unknown).
Field DB Field Name Req'd? Data Type Misc Flag List? Definition
ID taxonAlt_ID no serial PK no Database generated number to uniquely identify this record, and thus taxonGroup.
Taxon Interpretation taxonInterpretation_ID required Integer FK no Links to the taxonInterpretation for which several plantConcepts are grouped to form an irregular taxon. The plantConcept referenced here is one member of the group.
Plant Concept plantConcept_ID required Integer FK no Links to the plantConcept that is part of the taxonGroup formed by all records in this table with the same taxonInterpretation_ID.
Taxon Fit taxonAltFit no varchar (50) n/a closed Indicates the degree of fit with the plant concept being assigned. Values derive from Gopal, S., and Woodcock, C. (1994), Theory and methods for accuracy assessment of thematic maps using fuzzy sets. Photogrammetric Engineering and Remote Sensing 60(2):181-188.
Taxon Confidence taxonAltConfidence no varchar (50) n/a closed Indicates the degree of confidence of the interpreter(s) in the interpretation made. This can reflect the level of familiarity with the classification or the sufficiency of information about the plot (e.g., High, Moderate, Low).
Taxon Alt Notes taxonAltNotes no text n/a no These are notes that the interpreter has included with the interpretation (generally, the reason for the interpretation).
