NASA/NGA穿梭雷达地形任务（SRTM）收集了干涉雷达数据，该数据已被喷气推进实验室使用，以生成小于60度的纬度的Neor-Global地形数据产品。任务的主要目标之一是产生一个在全球范围内且量化错误的数据集。为了实现这一目标，NGA和NASA开展了广泛的全球基础运动，以收集地面真理，这将允许全球验证此独特的数据集。本文使用此全局数据集记录了此SRTM验证工作的结果。下面显示的表概述了我们的结果（所有数量代表90％的错误米）。[图形]在本文中，我们介绍了如何获得该表中的结果的详细说明，我们还提供了高度和计划的详细特征误差的组成部分，它们的幅度，地理分布和空间结构。
The NASA/NGA Shuttle Radar Topography Mission (SRTM) collected interferometric radar data which has been used by the Jet Propulsion Laboratory to generate a neor-global topography data product for latitudes smaller than 60 degrees. One of the primary goals of the mission was to produce a data set that was globally consistent and with quantified errors. To achieve this goal, an extensive global ground campaign was conducted by NGA and NASA to collect ground truth that would allow for the global validation of this unique data set. This paper documents the results of this SRTM validation effort using this global data set. The table shown below summarizes our results (all quantities represent 90 percent errors in meters).[GRAPHICS]In the paper, we present a detailed description of how the results in this table were obtained, We also present detailed characterizations of the height and planimetric components of the error, their magnitudes, geographical distribution, and spatial structure.
