Abstract

Digital Elevation Model represents elevation in two dimensional varying raster. It provides significant analysis of the terrain characteristics and planning. Availability of high-resolution satellites helps extraction of DEM at different global scales from the stereo imagery. Cartosat-1 is an along track sensor which acquire stereo data acquired continuously with fore and aft cameras. Stereo data including Rational Polynomial Coefficients (RPCs) is used to generate DEM based on standard Rational Polynomial Model. This paper evaluates the DEM generated from Ames Stereo Pipeline (ASP) for Carosat-1 stereo pair with Shuttle Radar Topography Mission (SRTM) DEM. The accuracy of the DEM extracted from ASP is tested with the standard SRTM DEM. The performance analysis shows that correlation of AMES DEM with SRTM shown 0.97 and RMSE of order 13.64m. The AMES DEM has shown high correlation and low RMSE values with the standard SRTM DEM.

由Cartosat-1立体对生成的DEM与SRTM DEM的比较——以印度Betul (M.P)为例

数字高程模型以二维变化栅格表示高程。它为地形特征和规划提供了重要的分析。高分辨率卫星的可用性有助于从立体图像中提取不同全球尺度的DEM。Cartosat-1是一种沿轨迹传感器，通过前后摄像头连续采集立体数据。利用包含有理多项式系数(RPCs)的立体数据，基于标准有理多项式模型生成DEM。本文将Ames立体管道(ASP)生成的DEM与航天飞机雷达地形任务(SRTM) DEM进行比较。用标准SRTM DEM对ASP提取的DEM精度进行了验证。性能分析表明，AMES DEM与SRTM的相关系数为0.97,RMSE为13.64m阶。AMES DEM与标准SRTM DEM具有较高的相关性和较低的RMSE值。
