介绍专题图可将GIS数据以丰富多彩的图表形式清晰地展示,是GIS表达空间数据的一种强有力方式.对GIS二次开发组件(OCX)制作专题图存在的不足进行了分析,主要包括专题图符号不能定量化、不能随机制作局部区域专题图、以及制作的多字段专题不便于用户的判断等.以抚州市综合水文管理信息系统的研发为例,选择MSChart与MSFlexGrid格网控件,结合可视开发语言VB,在ArcEngine平台下研究了Mschart支持的图形类型与水文专题图的制作,较好地解决了GIS二次开发组件制作专题图存在的问题.

Thematic map showed clearly GIS spatial data by a variety of charts which became a powerful way. The defects of using GIS component(OCX) to produce thematic maps were analyzed, including the thematic map cannot be quantitatived and can not product a random local area thematic map and can not be user judged by multi-fields producing thematic maps and so on. FuZhou City Comprehensive management information system for hydrological research and development set as an example, MSChart and MSFlexGrid grid control were choose, combining with visual development language VB, The producing process of graphic type and hydrology thematic map supported by Mschart were discussed at the platform of ArcEngine, which can better solve the problems in the using GIS component(OCX) to produced Thematic map.
