Oxbow lakes from the DRDLR:NGI data issued in May 2016 for the purpose of indicating floodplain wetlands. These oxbow lakes are in some instances indicative of the floodplain depressions, however some artificial systems were also mapped as Lakes by DRDLR:NGI. The polygon features called 'Lakes' were extracted and converted to points. The data was used by data capturers to guide them in the typing of hydrogeomorphic units, and can also be used when modelling HGM units. Please see Van Deventer et al. (2018) for more information.

Thermal springs (Olivier and Jonker, 2013). A thermal springs xlsx file was obtained for the purpose of guiding wetland mapping for the National Biodiversity Assessment (NBA) 2018 project. These coordinates were converted to points.

Springs (DRDLR:NGI, 2006 and 2016). The springs data was extracted from the hydrological point shapefile data issued by the DRDLR-NGI in September 2015. Springs can indicate potential origins of seep wetlands or rivers, and were used by the data capturers to assess sources of wetlands. It also provides the location of inland aquatic features that were not assessed in the NBA 2018. Please see Van Deventer et al. (2018) for more information.

Waterfalls Waterfalls were extracted from the DRDLR:NGI point data and supplemented by Heidi van Deventer from known waterfalls and those indicated by experts across the country.

Artificial wetlands of the South African Inventory of Inland Aquatic Ecosystems (SAIIAE). This data set is part of the Inventory released with the launch of the NBA 2018. National Wetland Map 5 includes inland wetlands and estuaries, but are associated with river line data and many other data sets within the South African Inventory of Inland Aquatic Ecosystems (SAIIAE).
