【摘要】 针对目前工程实践中存在的AutoCAD制图数据到ArcGIS关系数据的交换和管理,普遍存在着信息损失、效率低下、相对孤立、数据无法双向流动、难以更新等问题,进行了深入分析和研究,提出基于DwgDirect技术,辅助ArcEngine实现Auto-CAD数据到ArcGIS数据库的双向转换的方法,很好的解决了上述疑难问题,保证了CAD数据和GIS数据交换的高效性和严谨性。在实际的空间数据相关工程实践中带来了巨大变化。对实现空间数据建库和管理的真正一体化,本方法起着关键作用。更多还原

【Abstract】 In order to resolve the problem of data exchanging between ArcGis and AutoCad, which information lossless, isolated, difficult for update. A radical solution is presented which execute the exchange between ArcGis and AutoCad perfectly based on DwgDirect technology with ArcEngine technology. In this way, stumper are disentangled efficiently and rigorously. Great changes have taken place in practical projects on spatial database application. For the really spatial data manager continuum, this method is also a key point.更多还原
