 Remote sensing missions provide a wealth of complementary data that can be used to accurately determine land use and quantify subtle changes in land use management or intensity. However, most studies have focused on land cover rather than land use, and few have assessed the benefits of fusion over larger spatial scales. Fusion techniques should be developed to map the intricacies of land uses and changes therein, and systematic procedures should be implemented to evaluate the efficacy of these techniques at larger spatial scales.
