地图投影变换是ArcGIS的基础功能,其种类在ArcGIS 10软件中十分丰富,但其完整性、通用性及可扩充性有所不足,缺少适用于我国编制世界地图的重要投影(不等分纬线多圆锥投影)。为了解决这一问题,本文利用ArcGIS 10提供的Add-In技术,开发... 地图投影变换是ArcGIS的基础功能,其种类在ArcGIS 10软件中十分丰富,但其完整性、通用性及可扩充性有所不足,缺少适用于我国编制世界地图的重要投影(不等分纬线多圆锥投影)。为了解决这一问题,本文利用ArcGIS 10提供的Add-In技术,开发实现了不等分纬线多圆锥投影变换功能。 展开更多

Recently, double projection methods for solving variational inequalities havereceived much attention due to their fewer projection times at each iteration. In this paper, weunify these double projection methods within two unified frameworks, which contain the existingdouble projection methods as special cases. On the basis of this unification, theoretical andnumerical comparison between these double projection methods is presented. 展开更多
