Spatially representing of the confidence we have that the location, extent and HGM units of the inland wetland ecosystem types of South Africa are well represented.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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.</SPAN></P><P><SPAN /></P><P><SPAN>Publication Date 2018</SPAN></P><P><SPAN STYLE="font-weight:bold;">Attribute Definitions</SPAN></P><P><SPAN>OBJECTID_1 - System generated field object number.</SPAN></P><P><SPAN>SQ4_ - Sub-quaternary catchment (SQ4) code generated for the NFEPA project.</SPAN></P><P><SPAN>SQ4_ID - Sub-quaternary catchment (SQ4) identifier generated for the NFEPA project.</SPAN></P><P><SPAN>SQ4HASH - Sub-quaternary catchment (SQ4) identifier generated for the NFEPA project.</SPAN></P><P><SPAN>Wetlands_m - Indicative categories to show whether wetlands have been modelled, verified in full or partly or not at all.
