Statistical relational learning of semantic models and grammar rules for 3D building reconstruction from 3D point clouds
(2016-11-04)
Formal grammars are well suited for the estimation of models with an a-priori unknown number of parameters such as buildings and have proven their worth for 3D modeling and reconstruction of cities. However, the generation ...
Consistently closing global and regional sea level budgets
(2022-11-17)
Nowadays, human-induced climate change is the major driver of global and regional sea level change threatening the well-being and livelihoods of hundreds of millions of people living close to the coast. Consequently, ...
Untersuchungen zur Beschreibung, Verwaltung und Auswertung von Benutzer- und Berechtigungsprolen für objektorientierte Geoinformationssysteme
(2003)
Zur Beschreibung komplexer, raumbezogener Phänomene sind objektorientierte Datenmodelle besonders gut geeignet. Die natürlichen Strukturen sowie die Zusammenhänge von Realwelt-Objekten können dabei homogen und semantiknah ...
Non-invasive monitoring of water and solute fluxes in a cropped soil
(2010-12-15)
Although the influence of root water uptake on solute transport is commonly recognized as important, it has barely been studied throughout the literature. However, plants take up a big amount of the infiltrating water and ...
A global drought monitoring framework using GRACE/-FO data assimilation
(2024-12-09)
Extreme climate phenomena like droughts can lead to a shortage of available water resources that in turn can cause serious consequences such as famines. Monitoring of extremes is extremely important, and past research ...
Alterations of the nutrient uptake depth as inferred from radiogenic strontium isotopes in two case studies: a forest ecosystem and an agricultural field
(2026-03-31)
Climate change and its associated effects, such as higher temperatures and atmospheric CO2 concentration, pose increasing challenges to both forest and agricultural ecosystems. Nutrient uptake from deeper soil ...
Interpretation of Aerial Images with Learned Graphical Models
(2016-02-16)
In this thesis we present a new approach for image interpretation of aerial images using learned graphical models.
The approach uses a region based hierarchical feature adjacency graph. This contains homogeneous ...

Separablity of deformations and measurement noises of GPS time series with modified Kalman filter for landslide monitoring in real-time
(2011-08-04)
The separation of the deformations and measurement noise of GPS coordinate time series and accuracy improvement of GPS real-time coordinates are major aspects of the thesis. In order to reduce the influence of the colored ...
The role of abiotic processes in the formation and degradation of gaseous nitrogen compounds in the soil
(2015-09-24)
Soils are a major source of nitrogen (N) trace gases, especially of nitrous oxide (N2O) and nitric oxide (NO). The two microbial processes nitrification and denitrification are considered the major contributors ...
Extrinsic Calibration and Ego-Motion Estimation for Mobile Multi-Sensor Systems
(2018-12-20)
Autonomous robots and vehicles are often equipped with multiple sensors to perform vital tasks such as localization or mapping. The joint system of various sensors with different sensing modalities can often provide better ...
