BioSCape Invasive Alien Plant map for the Cape Floristic Region

BackgroundThis project was supported by the NASA BioSCape Project: “Impacts of Invasive Alien Species on Biodiversity and Ecosystem Functioning”. The training data used to produce this classification are also available. This dataset consists of a raw, unprocessed classification map of key woody invasive alien plant taxa (hereafter “trees”) within the Cape Floristic Region. This classification was generated using Sentinel-2 satellite imagery at a 10 m resolution using a Random Forest machine learning classifier. There has been no post-processing, and therefore it should be used with caution, especially in combination with the uncertainty layer provided.Dataset specificationsData type: Raster (tiff)Resolution: 10 mGeographic Coordinate System: WGS 1984Projected Coordinate System: Albers Equal Area projection (AEA)There is no EPSG for this, however the Well-Known Text (WKT) for this projected coordinate system is as follows:var wktAEA = 'PROJCS["AEA_RSA_WGS84",' +'GEOGCS["GCS_WGS_1984",' +'DATUM["D_WGS_1984",' +'SPHEROID["WGS_1984",6378137.0,298.257223563]],' +'PRIMEM["Greenwich",0.0],' +'UNIT["Degree",0.0174532925199433]],' +'PROJECTION["Albers"],' +'PARAMETER["False_Easting",0.0],' +'PARAMETER["False_Northing",0.0],' +'PARAMETER["Central_Meridian",25.0],' +'PARAMETER["Standard_Parallel_1",-24.0],' +'PARAMETER["Standard_Parallel_2",-33.0],' +'PARAMETER["Latitude_Of_Origin",0.0],' +'UNIT["Meter",1.0]]';PropertiesBands: This raster has two bands, the details of which are described in Table 1.Classes: Six classes of woody invasive alien plants were mapped in this classification (Table 2). This classification goes to genus level only and gives only presence/absence information together with information on uncertainty. Some classes were much harder to map than others and hence have higher uncertainty, such as Poplar and Hakea. A class was added for all the other invasive alien taxa which had large coverage though not enough for their own classes: “Other”.Training DataRebelo, AJ & Coertze, N. 2024.
