Digital Government: National Large-Scale City True Orthophoto Mapping and Its Standard Initiative

EIA-0131893周国庆老自治领大学数字政府：国家大比例尺城市正射影像图及其标准该笔赠款将用于支持一项更大的提案，以调查在城市地区使用数字正射影像图的新三维算法的开发。 目前在城市地区使用这种高分辨率地图已经发现了透视位移、高层建筑物遮挡、几何不准确以及无法创建大图像的无缝拼接的问题。 这笔赠款还将使与美国地质调查局的合作伙伴关系得到更全面的规划，该调查局负责国家数字正射摄影计划。

EIA-0131893Guoqing ZhouOld Dominion UniversityDigital Government: National Large-Scale City True Orthophoto Mapping and Its StandardThis grant will support planning for a larger proposal to investigate the development of new 3D algorighms for use of digital orthophoto maps in urban areas. Current usage of such maps at high resolution in urban areas has identified problems with perspective displacements, occlusions by tall buildings, geometric inaccuracies, and an inability to create a seamless mosaic of large images. The grant will also allow more complete planning of a partnership with the US Geological Survey, which runs the NationalDigital Orthophoto Program.
