Classification.zip: This file contains landform classification maps (.tif) for the Bislak (16 January 2017), Laoag (10 July 2018) and Abra (21 November 2019) Rivers. The data were derived from Sentinel-2 imagery and the multi-temporal optimal classification model. Downscaling_data.zip: this file gives downscaled images (.tif) of three image downscaling approaches (ATPRK, super-resolution and nearest neighbour resampling) for the Bislak River on 1 January 2018. Segmentation.zip: Shapefiles in this file show the image segmentation results by using ATPRK downscaled imagery (1 Januray 2018), super-resolution downscaled imagery (1 January 2018) and nearest neighbour resampling downscaled imagery (1 January 2018) in the Bislak River. They are segmentated to geographic objects and saved in .shp format. SVM_learning.zip: this file gives the training/testing datasets for selecting the optimal downscaling approach among ATRPK, super-resolution and nearest neighbour resampling approaches. This file also includes the optimal training dataset for classifying the multi-temporal landforms in three rivers. All data in this file are in LibSVM format for reading in Python v3.7.
