Description: This dataset was generated through an overlay analysis with the c.1800 pre-settlement wetland extent and represents the wetland distribution remaining in 2002. Pior to the overlay analysis land use categories in the 2002 SOLRIS dataset were standardized by collapsing related classes together. All natural features below 10 hectares were removed from the dataset to be consistent with the spatial accuracy constraints of the data, recognizing that the wetland extents would be underestimated. Standardized classes were then reclassified into 3 categories; natural cover, converted cover or no data. The reclassified data were then intersected with the c.1800 pre-settlement wetland. Features from the overlay that were below 10 hecatares were flagged as slivers. Where natural cover coincided with the pre-settlement wetland, the area was considered an existing wetland; where land cover was converted, the wetland was considered lost. This dataset contains only the existing wetland features.
