The Habitat Classification Tool
This tool enables consistent, and annually repeatable, mapping of habitats across the extent of Dartmoor National Park, not possible by previous field survey methods. It improves on current data provision by providing time series data that is easily updated and delivers a comprehensive baseline habitat data against which change can be detected.
The tool uses pixels of known habitat class to train a random forest classifier, with freely available Sentinel-2 satellite imagery combined with LiDAR data products (slope, aspect and elevation), to predict the most likely habitat class for each pixel across the mapped Dartmoor National Park area. It also provides measures of accuracy which enables the user to acknowledge the uncertainties within the map and therefore have an appropriate level of confidence in the mapped habitats.

The Habitat Change Detection Tool
This tool is designed to detect and map change over time in the habitat classes within Dartmoor National Park. It identifies and maps pixels where change has occurred in the mapped habitat class between two timeframes. It also provides a means to assess the accuracy of the mapped habitat change.
