Use of the SRTM DEM as a Geo-referencing Tool by Elevation Matching
DEM Co-registration Digital Photogrammetry Matching Topographic Mapping
2015/12/3
The method was then used to geo-reference old topographic maps of former Portuguese colonies, which were in local geodetic datums not well related to WGS-84. The consistency of planimetric datum shift...
Orientation and DEM Extraction from ALOS-PRISM Images Using the SRTM-DEM as Ground Control
Three-Line Matching DEM/DTM Georeferencing Orthorectification Accuracy
2015/11/24
This paper presents a methodology of image orientation and DEM extraction from ALOS-PRISM stereopairs without the use of GCPs. It uses the approximate geo-location information derived from the sensor ...
An Evaluation on the Data Quality of Srtm DEM at the Alpine and Plateau area, North-Western of China
DEM Shuttle Radar Topographic Mission (SRTM) evaluation Inferometric SAR (InSAR) land cover
2015/11/23
This paper evaluates the quality of SRTM3 data for alpine and plateau areas in Northwestern (NW) China against DEM data extracted from topographic maps. These SRTM data were obtained from both the ESR...
Reconstruction of 30m DEM from 90m Srtm DEM with Bicubic Polynomial Interpolation Method
Reconstruction DEM SAR Radar Resolution Accuracy
2015/11/23
This work presents a methodology for the refinement of 90m digital elevation model (DEM) of Shuttle Radar Topographic Mission (SRTM) data. The SRTM DEM is publicly available through the Seamless Data ...

SRTM DEM Orthoimage
2015/8/28
In the present paper, the position and elevation accuracy assessment of SRTM C-band DEM (90 m resolution) has been evaluated.
An accurate aerial photogrammetric DEM and orthophoto have been used as r...
基于SRTM-DEM的阿尔泰山构造地貌特征分析
SRTM-DEM 阿尔泰山 构造地貌
2009/11/23
基于美国SRTM-DEM数据，利用彩色晕染、密度分割与GIS空间统计分析等技术，并结合地质资料，通过地形高程、地表坡度
及地形剖面等分析手段，对阿尔泰山的构造地貌特征进行初步分析。研究表明，阿尔泰山脉平均海拔约1 790 m，平均坡度约21°
，其高海拔与高坡度的现代地貌特征，主要与强烈的断裂构造活动有关； 山脉严格受到以北西向为主的断裂构造活动的影响与控
制，其发育的构造地貌单元基本上呈北...
基于SRTM-DEM区域地形起伏的获取及应用
地貌 区域地形起伏 DEM
2009/11/23
基于数字高程模型（DEM）空间分析方法，利用SRTM采集的DEM数据，提出两种获取区域地形起伏的关键技术，即高程条带法（Swath Profile）和高程阈值法（Threshold Value），并通过扩展区域地形起伏获取的技术方法，初步实现了黄土高原典型地区侵蚀量的定量化分析。
