FROM-GLC-Hierarchy (Yuetal.,2014) is land cover dataset with multi-resolution ( i.e. 30m, 250m, 500m, 1km, 5km, 10km, 25km, 50km, 100km ) to meet requirements for different resolutions from different applications. The 30m base map was improved from FROM-GLC-agg with additional coarse resolution datasets (i.e.,MCD12Q1 (Friedletal., 2010),GlobCover 2009 (Bontempsetal.,2010)etc.) to reduce land cover type confusion. Around 1.1% pixels were replaced by coarse resolution products.
