HERRAULT Pierre-Alexis

Research activities

My current research include remote sensing for historical ecology and landscape ecology, image and point cloud processing for mapping ecological habitat. I am particularly interested in understanding how landscape changes affect biodiversity and how the exploration of old and current spatial data is relevant to solve this issue. I also conduct some works on uncertainty of spatial data and its propagation in environmental modeling. Collaborations with ecologists and paleoenvironmentalists are key in my research.
