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

数字政府：国家大尺度城市真正射影像测绘及其标准这项资助将支持一个更大的提案的规划，以研究在城市地区使用数字正射影像地图的新3D算法的发展。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、高层建筑遮挡、几何不准确以及无法创建大图像无缝拼接的问题。这笔拨款还将允许更完整地规划与美国地质调查局的合作关系，后者负责国家数字正射影像计划。

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.
