Can we model the effect of observed sea level rise on tides?
(2018-06-07)
The link between secular changes in the lunar semidiurnal ocean tide (M2) and relative sea level rise is examined based on numerical tidal modeling and the analysis of long-term sea level records from Europe, Australia, ...
Development, Calibration and Evaluation of a Portable and Direct Georeferenced Laser Scanning System for Kinematic 3D Mapping
(2016-01-21)
In recent years, kinematic laser scanning has become increasingly popular because it offers many benefits compared to static laser scanning. The advantages include both saving of time in the georeferencing and a more ...
Analysis of Different Reference Plane Setups for the Calibration of a Mobile Laser Scanning System
(2017)
The discipline of engineering geodesy is currently subject to a paradigmatic change because the measuring of carefully selected single points is progressively replaced by an area-based acquisition of structures in form of ...
Dealing with systematic laser scanner errors due to misalignment at area-based deformation analyses
(2018-03-07)
The ability to acquire rapid, dense and high quality 3D data has made terrestrial laser scanners (TLS) a desirable instrument for tasks demanding a high geometrical accuracy, such as geodetic deformation analyses. However, ...
Empirical stochastic model of detected target centroids: Influence on registration and calibration of terrestrial laser scanners
(2019-03-22)
The target-based point cloud registration and calibration of terrestrial laser scanners (TLSs) are mathematically modeled and solved by the least-squares adjustment. However, usual stochastic models are simplified to a ...
Exact Optimization Algorithms for the Aggregation of Spatial Data
(2020-12-16)
The aggregation of spatial data is a recurring problem in geoinformation science. Aggregating data means subsuming multiple pieces of information into a less complex representation. It is pursued for various reasons, like ...
Konsistente Kombination von Schwerefeld, Altimetrie und hydrographischen Daten zur Modellierung der dynamischen Ozeantopographie
(2012-07-18)
Die dynamische Ozeantopograpie als Differenz zwischen Meeresoberfläche und dem Geoid reflektiert charakteristische Merkmale der Ozeanzirkulation und stellt als gemessene Größe somit eine bedeutende Eingangsgröße in ...
Attributierte Grammatiken zur Rekonstruktion und Interpretation von Fassaden
(2012-03-19)
Dem Bedarf und Nutzen hoch detaillierter 3D-Stadt- und Gebäudemodelle steht deren aufwendige Erfassung gegenüber. Ist die automatische Ableitung vereinfachter Dachstrukturen aus Luftbildern oder Laseraltimetrie weitestgehend ...
Role of termites for the distribution patterns of carbon and phosphorus fractions and the genesis of tropical soils, Brazil
(2012-07-27)
Tropical soil fertility is limited by low phosphorus (P) availability, limited accumulation of organic matter and by advanced stages of pedogenesis. Termites are well-known soil-engineers, which accumulate clay, organic ......
Die Bedeutung von Termiten für die Verteilungsmuster von Kohlenstoff- und Phosphor-Fraktionen sowie die Genese Tropischer Böden, Brasilien
Die Bodenfruchtbarkeit in den Tropen ist durch eine geringe ......
A fertilidade dos solos tropicais é limitada pela baixa disponibilidade de fósforo, a falta de acumulação de matéria orgânica, e por estados avançados de pedogênese. Os térmitas ou cupins são bem-conhecidos 'engenheiros ......

Wet Path Delay Corrections from Line-of-Sight Observations of Effelsberg’s Water Vapour Radiometer for Geodetic VLBI Sessions
(2012-08-01)
Water vapour induced excess path lengths in electromagnetic waves have been one of the most unmanageable errors in space geodesy, such as GPS and VLBI. The difficulty mainly comes from the highly variable distribution of ...
