摘要
为了充分共享利用已有数据成果,MapGIS地图数据经常需要向ArcGIS格式转换。然而现有的转换方法常出现属性、投影、注记丢失,图面无法渲染,其结果不能达到制图质量要求。文章通过对MapGIS6X和ArcGIS平台下的图件数据结构组织、渲染方式等进行分析研究,并结合两个平台的二次开发技术,提出了一套半自动化实现转换的技术流程,开发了地图数据转化的相关软件工具和扩展插件,在实践中有效地解决了转换过程中信息丢失、任务繁重等问题。
In order to fully use and share the existed data, it＇s a very common demand to convert a large number of map data from MapGIS format to ArcGIS format. However, the attributes, projections, annotations are usually lost and the features cannot be rendered with previous methods, the result cannot meet the quality requirements. Based on the analysis of the data structure organization and rendering expression of the MapGIS6X and ArcGIS platforms, this paper summarized a set of semi-automatic technology process of conversion, and developed some software tools and extension plugins for the data convention by using secondary development technology, which could effectively solve the problems of heavy workload, information lost and others in the conversion process.
