BioSCape Processed Training Dataset

These data are collected for the NASA-funded BioSCape Project: “Impacts of Invasive Alien Species on Biodiversity and Ecosystem Functioning”. This particular dataset is curated for the alien tree classification of the NASA airborne remote sensing data. The dataset includes training data points of invasive alien trees and other classes for the three study sites in Cape Floristic Region (Figure 1). The dataset was prepared according to the following pre-agreed criteria:

• As many points as possible were collected
• The classes needed to be even (same number of training points) for the machine learning algorithms
• Points didn’t need to be paired (i.e. paired invasive alien tree and fynbos points)
• It was not necessary to collect training data in all sampling units, though a general effort to avoid bias and to sample across different sampling units was attempted
