The uMRC_IAPs_2024_GCS_V1.0 feature class has been developed to characterise the many invasions of the uMngeni River Catchment by invasive alien plants (IAPs). This includes information regarding species, distribution patterns, accessibility and extent of riparian invasion. IAP information is captured against a wall-to-wall set of polygon features called segments. Segments were generated using the segment mean shift tool in ArcGIS and Sentinel 2A imagery of 10m spatial resolution. These were then manually adjusted to better fit the landscape. IAP information was captured for segments through interviews with local experts in a workshop setting, through field work and through extracting information from existing IAP mapping data products, predominantly data from the Working for Water programme and data from the SEBEI project.
