CONSIDERATION AND EXPLORATION ON THE DEMAND CHANGES OF SURVEYING AND MAPPING GEOGRAPHIC INFORMATION

Abstract. This article primarily describes the nature of geoinformatics, including the role of each of its components as understood today, and illustrates how the change in demand and the progress in science and technology are the two driving forces for the development of this subject. The changes in popular needs are next analyzed in detail, focusing on four aspects: the user group, intended usage, medium, and service. Lastly, it points out that geoinformatics work should be conducted following the development of geographic information.
