Name: National Wetlands Confidence (NBA 2018)

Display Field: PROVNAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The confidence map was compiled to identify areas where wetland extent and hydrogeomorphic (HGM) units (which contributed to defining the inland wetland ecosystem types together with the regional setting) attained at a higher level of certainty compared to other areas. Higher levels of certainty are associated [code 5 in field Confidence_nr] with areas that have been visited in-field by a wetland specialist(s) over multiple seasons and cycles of the wetland hydroperiod, and are therefore more accurately represented in the dataset. Codes 4 to 1 indicate lower levels of confidence that the extent and HGM unit are represented well.Publication Date 2018Attribute DefinitionsOBJECTID_1 - System generated field object number.SQ4_ - Sub-quaternary catchment (SQ4) code generated for the NFEPA project.SQ4_ID - Sub-quaternary catchment (SQ4) identifier generated for the NFEPA project.SQ4HASH - Sub-quaternary catchment (SQ4) identifier generated for the NFEPA project.Wetlands_m - Indicative categories to show whether wetlands have been modelled, verified in full or partly or not at all. Types include:ModelPartValidatedYesSQ4_Ha - Original extent of the SQ4 (generated in the NFEPA project) in hectares before it was unioned with the province boundaries.Province - Abbreviation for province in which wetland occurs.PROVNAME - Name of the province.Area_ha - Updated area in hectares after union with provinces.Wetmap_cat - Category of details available as per published journal paper Van Deventer et al. (2018) in WaterSA.Confidence_nr - Confidence category to use in association with the NWM5. See van Deventer et al. (2018) SAIIAE report for more information.Shape_Length - Perimeter of polygon (m). This field was automatically generated within the geodatabase.Shape_Area - Area of polygon (m2 ). This field was automatically generated within the geodatabase.
