BSRLC+: An annual land cover dataset for the Baltic Sea Region with crop types and peat bogs at 30 m from 2000 to 2022

(NEW) Baltic Sea Region Land Cover Urban (BSRLC-U) focusing on urban built-up types now available: https://zenodo.org/records/17413880 

Baltic Sea Region Land Cover Plus (BSRLC+) is annual land cover mapping (30 m) dataset in Europe from 2000 to 2022. The maps 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) / 9 (OLI+) and Sentinel 2 (A / B ) from 2000 to 2022. Data is processed to surface reflectance and tiled into datacube structure using Framework for Operational Radiometric Correction for Environmental monitoring - FORCE.

Mapping method: Maps are produced using data encoding and deep learning classification according to Pham et al. 2024

Validation: Maps have been rigorously validated using independent in-situ data The Land Use/Cover Area frame Survey (LUCAS). 

Traing data and validation data are available: https://zenodo.org/records/11073291
