 Remote-sensing missions provide valuable data for accurately determining land use and tracking subtle changes in land management or intensity, but only 50 out of 112 studies specifically addressed land use analysis, with a majority focusing on land cover. Fusion of optical and radar data improved results compared to using single data sources in 28 out of 32 studies that assessed the advantages of fusion for land use analysis. However, study sites were small and there was a lack of comparison of results and accuracies across sites. The development of robust techniques for mapping land uses and changes and systematic procedures to assess the benefits of fusion over larger spatial scales is necessary for progress in this field of research.
