The study utilizes Landsat 9 data (OLI-2 and TIRS-2 sensors) to create a geological map of Dak Nong province, Vietnam. By applying spectral analysis methods (PCA, band ratios), image classification techniques (SAM, CEM), and integrating field surveys, the research identified four main geological units: Quaternary sediments, Jurassic sedimentary rocks, basalt, and Cretaceous granite. The results demonstrate that Landsat 9 achieves high accuracy in geological mapping, particularly for basalt (with an error of only 0.68%). However, its ability to distinguish sub-units and areas with complex surface coverage remains limited, requiring support from field surveys to improve reliability
