tblGeoLevel1, shared across files, continent or other major part of the world. This table and the next two tables are copied from Brummitt, R. K. 2001: World Geographical Scheme for Recording Plant Distributions. Plant Taxonomic Database Standards No. 2, Edition 2. International Working Group on Taxonomic Databases (TDWG). Hunt Institute for Botanical Documentation, Pittsburgh. [TDWG Standard] [Electronic version available under http://www.tdwg.org/geo2.htm.] NOTE: The row for no information (Level1ID = "0") has information for columns from MinL2AreaValue to Level2AllMask that applies to tblTaxa.Distribution1Flags, not to tblTaxa.Distribution2WFlags, Distribution2CFlags or Distribution2EFlags.
Level1ID, character, 1 byte, identifier for "continent" Name, text, 16 bytes maximum, name BitValue, integer, 4 bytes, value of the bit that indicates this level 1 area in tblTaxa.Distribution1Flags MinL2AreaValue, integer, 4 bytes, value of the lowest bit in tblTaxa.Distribution2WFlags, Distribution2CFlags or Distribution2EFlags that signifies a subarea within this level 1 area. Deleted in version 3.5. MaxL2AreaValue, integer, 4 bytes, value of the highest bit in tblDistribution.AreaFlags that signifies a subarea within this level 1 area Level2AreaMask, integer, 4 bytes, mask for all the bits in tblDistribution.AreaFlags Level2StatusFactor, integer, 4 bytes, value of the lower bit in tblTaxa.Distribution2WFlags, Distribution2CFlags or Distribution2EFlags for the status of information. Deleted in version 3.5. Level2StatusMask, integer, 4 bytes, mask for the two status bits (= 3 * Level2StatusFactor). Deleted in version 3.5. Level2AllMask, integer, 4 bytes, combined bit values for Level2AreaMask and Level2StatusMask. Deleted in version 3.5.
