BSRLC-U: A tri-annual urban built-up types for the Baltic Sea Region at 10 m from 2000 to 2021

Baltic Sea Region Land Cover Urban (BSRLC-U) is tri-annual land cover mapping (10 m) dataset in Europe from 2000 to 2021. The maps contain detailed information of urban built-up classes: 1) Residential buildings, 2) Industrial buildings, 3) Open spaces and 4) Non built-up. BSRLC-U is a complementary dataset to the existing Baltic Sea Region Land Cover Plus (BSRLC+) dataset, which contain detailed information of 18 land cover (LC) types, including 9 crop types and 2 peat bog types

Input data : Optical multi-temporal remote sensing imageries (Landsat 5 (TM) / 7 (ETM+) / 8 (OLI)  and Sentinel 2 (A / B ) from 1999 to 2022. Data is processed to surface reflectance and tiled into datacube structure using Framework for Operational Radiometric Correction for Environmental monitoring - FORCE.
