A Relief Dependent Evaluation of Digital Elevation Models on Different Scales for Northern Chile

Publikováno v: ISPRS International Journal of Geo-Information, Vol 8, Iss 10, p 430 (2019)

Many geoscientific computations are directly influenced by the resolution and accuracy of digital elevation models (DEMs). Therefore, knowledge about the accuracy of DEMs is essential to avoid misleading results. In this study, a comprehensive evalua

Accuracy Assessment of Landform Classification Approaches on Different Spatial Scales for the Iranian Loess Plateau

Autor: Tanja Kramm, Dirk Hoffmeister, Constanze Curdt, Sedigheh Maleki, Farhad Khormali, Martin Kehl

Publikováno v: ISPRS International Journal of Geo-Information, Vol 6, Iss 11, p 366 (2017)

An accurate geomorphometric description of the Iranian loess plateau landscape will further enhance our understanding of recent and past geomorphological processes in this strongly dissected landscape. Therefore, four different input datasets for fou

EVALUATION OF DIGITAL ELEVATION MODELS FOR GEOMORPHOMETRIC ANALYSES ON DIFFERENT SCALES FOR NORTHERN CHILE

Autor: Tanja Kramm, Dirk Hoffmeister

Publikováno v: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XLII-2-W13, Pp 1229-1235 (2019)

The resolution and accuracy of digital elevation models (DEMs) have direct influence on further geoscientific computations like landform classifications and hydrologic modelling results. Thus, it is crucial to analyse the accuracy of DEMs to select t

Assessing the influence of environmental factors and datasets on soil type prediction with two machine learning algorithms in a heterogeneous area in the Rur catchment, Germany

Autor: Tanja Kramm, Dirk Hoffmeister

Publikováno v: Geoderma Regional. 22:e00316

Machine Learning (ML) algorithms are a promising alternative to traditional acquisition methods for creating new or updating existing soil maps. This study analyses the suitability of three ML techniques for the prediction of 36 different soil types

First Exit of Brownian Motion from a One-sided Moving Boundary

Autor: Tanja Kramm, Frank Aurzada

Publikováno v: High Dimensional Probability VI ISBN: 9783034804899

We revisit a result of Uchiyama (1980):giv en that a certain integral test is satisfied, the rate of the probability that Brownian motion remains below the moving boundary f is asymptotically the same as for the constant boundary. The integral test f
