NZLDD V1 QualityRanking

The QualityRankings table records the quality of each source dataset or reference. Where multiple references are given in the feature classes, the ranking of the highest overall quality record is assigned to the dataset. For example, if a previously-mapped dataset was updated by the Version 1.0 NZ Landslide Dam Database authors using more recent satellite imagery or terrain models, then the metadata record for the updated mapping is linked to the landslide DamSite points via the Metadata ID field. In Version 1.0 of the database, this table contains attributes that are specific to the quality of the whole source dataset, not individual landslide dams. This might be improved in future versions of the database.
