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

EIA-0131893国庆周老自治区大学数字政府：国家大型城市真实正射影像测绘及其标准这笔赠款将支持规划一项更大的提案，以调查城市地区使用数字正射影像地图的新3D算法线条的开发。目前在城市地区使用高分辨率这类地图发现了透视位移、高楼遮挡、几何不准确以及无法创建大图像的无缝马赛克等问题。这笔赠款还将允许更全面地规划与美国地质调查局的合作伙伴关系，后者负责运营国家数字正射影像计划。

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.
