DEM quality assessment for quantification of glacier surface change
Photogrammetric digital elevation models (DEMs) are often used to derive and monitor surfaces in inaccessible areas. They have been used to monitor the spatial and temporal change of glacier surfaces in order to assess glacier response to climate change. However, deriving photogrammetric DEMs of steep mountainous topography where the surface is often obscured by regions of deep shadow and snow ...
متن کاملassessment of the park- ang damage index for performance levels of rc moment resisting frames
چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
15 صفحه اولStatus of TanDEM-X DEM Calibration and Mosaicking towards the TanDEM-X DEM
With begin of 2013 DEM production started with the generation of the Intermediate TanDEM-X DEM (IDEM) for selected science and commercial test sites. This paper gives an overview of the Intermediate DEM production that took place from end of 2012 until July 2013. It describes the DEM production process and the lessons learnt by the IDEM phase. Since autumn 2013 the final DEM generation has begu...
متن کاملFast glacier volume change detection based on least squares 3D surface matching of DEM
In this paper, a new fast detection method on glacier volume changing has been adopted and analyzed to solve shortages of low precision and inefficiency in traditional algorithms. High-precision Digital Elevation Model (DEM) has been used in this method to improve the accuracy of the result. Besides, GCPs are unnecessary in this new method so that it can be widely applied in glacier districts w...
متن کاملImpact of resolution and radar penetration on glacier elevation changes computed from DEM differencing
Digital elevation models (DEMs) are now frequently used to calculate elevation changes and regional mass balances of glaciers, for example in the Alps (Berthier and others, 2004; Paul and Haeberli, 2008; Huss and others, 2010), Alaska and Canada (Larsen and others, 2007; Schiefer and others, 2007; Berthier and others, 2010), Patagonia (Rignot and others, 2003) or High Mountain Asia (Surazakov a...
