Evaluation and Normalization of Topographic Effects on Vegetation Indices [PDF]
Remote Sensing, 2020 The normalization of topographic effects on vegetation indices (VIs) is a prerequisite for their proper use in mountainous areas. We assessed the topographic effects on the normalized difference vegetation index (NDVI), the enhanced vegetation index (EVI), the soil adjusted vegetation index (SAVI), and the near-infrared reflectance of terrestrial ...

Topographic Effects in Geoid Determinations [PDF]
Geosciences, 2018 Traditionally, geoid determination is applied by Stokes’ formula with gravity anomalies after removal of the attraction of the topography by a simple or refined Bouguer correction, and restoration of topography by the primary indirect topographic ...

On the topographic effects by Stokes’ formula
Journal of Geodetic Science, 2014 Traditional gravimetric geoid determination relieson Stokes’ formula with removal and restoration of thetopographic effects. It is shown that this solution is in errorof the order of the quasigeoid-to-geoid difference, which ismainly due to incomplete ...

Dizhen xuebao, 2022 地表不规则地形的存在往往会引起地震波的散射，进而产生局部地震动放大或衰减的现象。虽然地形效应最早在异常地震记录中被发现，然而利用地形影响台阵记录到的地震动数据却少之又少。基于1992年在我国台湾翡翠河谷上观测到的六条地形影响台阵记录，利用线源SH波入射下非对称V形河谷地震波传播解析理论，模拟得到了河谷台阵各点的地震动，揭示了翡翠河谷地形效应对地震动影响的规律。与实测记录的对比结果表明利用笔者提出的地震波传播解析理论能够较好地反映河谷地形对地震动的影响。

Vegetation Growth Status and Topographic Effects in Frozen Soil Regions on the Qinghai–Tibet Plateau
Remote Sensing, 2022 The Qinghai–Tibet Plateau (QTP), which is known as Earth’s “Third Pole”, is a driver of global climate change, and long-term monitoring of QTP vegetation can reveal changes attributable to climatic and human influences.

The Effects of Hydration on the Topographical and Mechanical Properties of Corneocytes
Journal of the Mechanical Behavior of Biomedical Materials, 2023 It is well established that the biomechanical properties of the Stratum Corneum (SC) are influenced by both moisture-induced plasticization and the lipid content. This study employs Atomic Force Microscopy to investigate how hydration affects the surface topographical and elasto-viscoplastic characteristics of corneocytes from two anatomical sites ...
