Count QC flags set.
qcflags(qc, id)The QC value as returned from the occurrence method.
The QC flag ids.
Number of QC flags set.
At the moment there are 27 QC flags, numbered from 1 to 30 with disabled flag (qc 8, 9 and 20).
1. OBIS data format: are the required fields from the OBIS Schema completed?
2. Taxonomy: is the taxon name matched to WoRMS?
3. Taxonomy: is the taxon level genus or lower?
4. Geography (lat/lon): are the latitude/longitude values different from zero?
5. Geography (lat/lon): are the latitude/longitude values within their possible boundaries? (world coordinates)
6. Geography (lat/lon): are the coordinates situated in sea or along the coastline (20 km buffer)?
7. Completeness (date/time): is the sampling year (start/end) completed and valid?
10. OBIS data format: is the 'Basis of Record' documented, and is an existing OBIS code used?
11. Completeness (date/time): is the sampling date (year/month/day; start/end) valid?
12. Completeness (date/time): if a start and end date are given, is the start before the end?
13. Completeness (date/time): if a sampling time is given, is this valid and is the time zone completed?
14. Completeness (presence/abundance/biomass): is the value of the field 'ObservedIndividualCount' empty or >0?
15. Completeness (presence/abundance/biomass): is the value of the field 'Observedweight' empty or >0?
16. Completeness (presence/abundance/biomass): is the field 'SampleSize' completed if the field 'ObservedIndividualCount' is >0?
17. OBIS data format: is the value of the field 'Sex' empty or is an existing OBIS code used?
18. Geography (depth): is minimum depth <= maximum depth?
19. Geography (depth): is the sampling depth possible when compared with GEBCO depth map (incl. margin)?
