An Audit Of Some Filtering Effects In Aggregated Occurrence Records

These files include original and processed data from a study of data filtering by the Atlas of Living Australia (ALA) and the Global Biodiversity Information Facility (GBIF). The study has been submitted for publication on 2018-03-04 as the paper "An audit of some filtering effects in aggregated occurrence records" and details of data sources and processing are in that manuscript. ALA and GBIF sourced occurrence records from the Australian Museum (AM) [Malacology], Museums Victoria (MV) [Entomology] and the New Zealand Arthropod Collection (NZAC). The unprocessed ALA and GBIF data are in the zipped files AM-ALA_download.zip, MV-ALA_download.zip, AM-GBIF_verbatim.download.zip, AM-GBIF_occurrence.download.zip, MV-GBIF_verbatim.download.zip, MV-GBIF_occurrence.download.zip, NZAC-GBIF_verbatim.download.zip and NZAC-GBIF_occurrence.download.zip. The processed data are in a single zip file name_change_tables_and_data_notes.zip. The processed data are my own work and are here made available under a CCA 4.0 licence.
