We are witnessing the exploding development of Mobile Geoinformation Services(MGS). However, MGS is a complex system engineering involving many different technological fields or disciplines. There are many problems still existing and deserving to be further clarified and studied. Based on the analysis of the derivation of MGS and different
related terms, a relatively universal concept of MGS is first defined in this paper. After that, this paper illuminates the present application level in China by summarizing the five modes that exist in all application related to MGS. In addition, five aspects of problems that hinder MGS from developing on a large scale are put forward. Finally the paper concludes that the implementation of MGS can be only performed on a limited basis in current China and there are still many barriers that prevent MGS from reaching its full potentials.
