WANG Yandong WU Xiaodi GONG Jianya(State Key Laboratory of Information Engineering in Surveying,Mapping and Remote Sensing,Wuhan University,129 Luoyu Road,Wuhan 430079,China)  
In our study,Situation-Symbols were divided into three kinds:single-arrows,complex-arrows and multi-arrows,in order to set up different kinds of situation-symbol models.Such situation-symbol models were carried out by expending secondary development of ComGIS.These models include all arrows and could be developed.It is indicated by experiments that these arrows work well on the platform of ComGIS and accord with the demands of situation-map.
