Lineage |
Reef bioregions: See Technical Report on the Classification Phase of the Representative Areas Program by Kerrigan, Breen et al, 1999 (in progress) Bounding polygons: Thiessen polygons were constructed for all reefs, and then dissolved by bioregion. Reefs were buffered by 10 km, overlayed with the Thiessen coverage, and then dissolved by bioregion again. |
Positional Accuracy |
Generally +- 125 metres, as it relies partly on locational accuracy of other base GBRMPA datasets, namely REEFS, ISLANDS, COAST. |
|
Attribute Accuracy |
Attribute ‘bioregion’ came from nonreefbioregion in the non-reef coverage and reefbioregion in the reef coverage. Field bioregion relates to the unique id field (bioregion) in the lookup table bioregion.lut. The values correspond to the reefbioregion and nonreefbioregion attributes of the separate datasets. Final reef bioregion names are stored in the look up table in the field short_desc. Field Label is the short version of the final short_desc field for the purpose of processing |
|
Logical Consistency |
WHA boundary coincides with COAST, parts of GBRMP ZONING, GBRMP and WHAGBR. Reef bioregions are logically consistent with the REEFS coverage. |
|
Completeness |
The bioregions of the Great Barrier Reef World Heritage Area evolve as more accurate data becomes available. |
