The Great Barrier Reef (GBR) land use mapping 2021 dataset is a digital land use map for the GBR catchment area. The dataset encompasses the 2021 update of land use mapping series for the six GBR Natural Resource Management (NRM) regions: Cape York, Wet Tropics, Burdekin, Mackay Whitsundays, Fitzroy, and Burnett Mary. The assignment of land use classes to the dataset was based on image interpretation of multi-temporal Landsat, Sentinel, Earthi and high spatial resolution SPOT and Pleiades satellite imagery, as well as ancillary datasets containing land use information and field observations. Attribution of land use classes is based on a modified Australian Land Use Management Classification (ALUMC) Schema, Version 8 (October 2016). The ALUMC schema was aggregated to thirty-one land use classes and mapped in the Great Barrier Reef (GBR) land use mapping 2021 dataset. A table showing the aggregation of ALUM codes used in this dataset can be downloaded from here:https://www.data.qld.gov.au/dataset/2021_great_barrier_reef_land_use/resource/51cca2d0-5d1f-4588-aa8b-e6a1f964fea2. Mapping was done predominantly at ALUMC ‘s secondary level classes but with some classes only to the primary and tertiary level. A diagram of the ALUMC aggregation can be downloaded from the following link https://www.data.qld.gov.au/ckan-opendata-attachments-prod/resources/3e72d679-8126-488a-bc7f-c2fbf42c0455/alumv8_qlump_2021classesmapped.pdf?ETag=6e34c948daa3b4b14bbf6a384a9c6bc1
