摘　　要：本文根据同名像点存在的几何位置关系,提出一种利用POS数据进行像点坐标粗差检测的方法,用模拟数据验证了方法的正确性和有效性,并利用两组不同摄影比例尺的实际航摄资料进行了试验。试验表明,用该方法剔除像点坐标中的粗差后,立体像对相对定向精度得到很大提高。在保证POS数据内部相对精确的情况下,其整体系统误差对粗差检测结果没有影响。In the actual secondary development pattern of GIS, some problems still exist. For resolving them, this paper put forward a framework pattern of plug-in GIS secondary development which would be more prone to developing and applying. This application framework is based on ArcEngine and . NET development platform, using plug-in development techniques, according to the specification of ArcOhjeets interface, realizing the ArcOhjects interface, rewriting main framework class and forming encapsulation. To achieve the purpose of easily customizing the application, using XML Configuration Management, the application framework can dynamically create the menu, toolbar, floating panels and so on. In the end, an example of land GIS application was illustrated the technology route for realizing the framework.
