Availability: If you are interested viewing or using either the THaW Mapping Dataset or the THaW Change Detection tool for non-commercial use, please contact Dr David Luscombe d.j.luscombe@exeter.ac.uk.
Following publication later in 2021, it is anticipated that this dataset and tool will both be available via an online open access repository, © 2021. licensed under a CC BY-NC-SA 4.0 license.
The THaW Mapping Toolbox
This Toolbox autonomously and rapidly generates high resolution, baseline THaW maps, across landscape extents, using 2m2 LiDAR Data and bespoke data processing approaches. See figure 1 for example outputs.

The THaW Change Detection Tool
Drawing on THaW mapping data and spaceborne radar data, this tool adds an online platform which can autonomously detect changes to the mapped THaW habitats, through time. Using Sentinel I synthetic aperture radar (SAR) data, this tool enables remotely sensed canopy change detection to be mapped for any calendar quarter selected by the user, enabling close to real time tracking of canopy loss and woodland management. See figure 2 for example outputs.
