Abstract The main purpose of the mineral resources potential assessment research based on the remote sensing method in Tibetan region is to extract abnormal remotely sensed information， make several kinds of geological maps，and provide basic maps and data for other cooperating research groups. Four typical problems have appeared in the project because of vast area， multi-temporal remote sensing images，too much software，complex processes and technical differences in technicians’ professional background and experience. The first problem is the incorrect understanding of the datum and map projection and the ignoring of the remote sensing image map projection distortion； the second problem is deleting too much or too little interference information and incomplete spatial topological relations during the anomaly information extraction； the third problem is the inappropriate strategy of remote sensing image mosaicking and color balancing； the fourth problem is low accuracy in the interpretation of geological features of mineral resources. Focused on these four problems，this paper proposed a practical solution which ensures the successful completion of the remote sensing project.
