21st century land cover change across the major proglacial regions of West Antarctica and the McMurdo Dry Valleys
We present here the land cover change of the major proglacial regions in West Antarctica and the McMurdo Dry Valleys during the 21st century. We have used change vector analysis on Landsat-8 Operational Land Imager (OLI) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) images to an accuracy of 80 %.

- Statement
- First, we calculated the resubstitutuion error to assess the differences between the training data classes and predictions the classifier made. This shows the accuracy of the model based on the training data made available to it was 100.0 %. To validate the accuracy of our change maps, we reproduced the change detection analysis on Byers Peninsula with a 70/30 split of the training points between the classifier and validation. To ensure this split was unbiased, we randomly sorted the training points. This showed a total validation of accuracy of 80.1 %.
