GBIF Data Quality Requirements and Documentation

Official GBIF documentation on data quality requirements for publishing occurrence, checklist, and sampling-event datasets. Describes over 50 automated data quality flags that GBIF applies during data ingestion, covering taxonomic validation (name matching against the GBIF backbone taxonomy), spatial validation (coordinate range checks, country centroid detection, zero-coordinate flagging), temporal validation (date parsing, future-date detection), and logical consistency checks. Includes links to the GBIF Data Validator tool for pre-publication review of Darwin Core Archives, IPT Excel templates, and CSV files. Essential reference for data managers preparing freshwater biodiversity datasets for publication — helps identify and fix common issues before data reaches the GBIF network.
