Soltani et al. present an automated workflow for transforming weakly annotated citizen science plant photographs into robust training data for drone-based remote sensing of vegetation. Their approach demonstrates that plant images collected by non-specialists can be effectively leveraged in machine learning models to improve the accuracy of species mapping using drones.

Short summary
We introduce an automated approach for generating segmentation masks for citizen science plant photos, making them applicable to computer vision models. This framework effectively transforms citizen science data into a data treasure for segmentation models for plant species identification in aerial imagery. Using automatically labeled photos, we train segmentation models for mapping tree species in drone imagery, showcasing their potential for forestry, agriculture, and biodiversity monitoring.
