Geographic information standardization is confronted with the urgent challenges of the rapid growth of geographic information industry in China. Although the past years witnessed great achievements in standardization of applications in this field, we still have no breakthrough work for some essential problems. In order to accelerate the standardization development,“12^th Five-Year Planning for surveying, mapping and geographic information standardization”took the construction of geographic information standard system and sub-systems as the top priority task. In this paper, we reviewed the progress in geographic information standardization system, and elaborated the importance of geographic information software standard system construction for geographic information industry. Based on the analysis of existing national geographic information standard system, we found three typical problems which greatly hindered development of geographic information software standardization, and discouraged participation from enterprises and institutions in further. The solution is building an independent geographic information software standard sub-system compatible with existing standard system. In pursuit of this objective, we first chose the geographic information software classification system as the base of standard system discreetly, then declared the objectives and principles of system construction, at last made the recommended draft of geographic information software standard system framework diagram and class table, which consists of six main classes, as (1) Basic Platform Software; (2) Data Acquisition and Production Software; (3) Data Management Software; (4) Data Analysis and Mining Software; (5) Application and Service Software; and (6) Application System. Finally, we made the conclusion of project status and prospected the future developments.
