from Van der Plas, Geikie, Alexander and Simms, upcoming publication titled Multi-stage semantic segmentation quantifies fragmentation of small habitats at a landscape scale

This data set contains the RGB image data and human land cover annotation for 1027 patches of 512 pixels x 512 pixels ( 64 m x 64 m spatial resolution). 

For more information on how the data can be used, the land cover schema and other details, please see our paper. For code examples of how to use the data, please see the github repository at https://github.com/pdnpa/cnn-land-cover

The data is given in two formats: python and tiff. The Python format can be directly loaded by the code in the repository into Pytorch DataLoaders. The tiff format is independent of  progamming language and application.
