Konzept zur Harmonisierung und Präsentation von Nutzungsdaten auf Grundlage des 3A-Modells
(2010-06-04)
Mit dem AFIS®-ALKIS®-ATKIS®-Anwendungsschema hat die AdV ein modernes Konzept zur integrierten Führung der Geobasisdaten des amtlichen Vermessungswesens geschaffen. Die verschiedenen Grunddatenbestände des Liegenschaftskatasters, ...
Zur Entwicklung und Bewertung der absoluten GNSS-Antennenkalibrierung im HF-Labor
(2010-07-09)
Bei der relativen Positionsbestimmung mit GNSS-Verfahren stellen die Antenneneinflüsse, die sich durch eine richtungsabhängige Empfangscharakteristik auszeichnen, einen der die Genauigkeit begrenzenden Faktoren dar. Durch ...
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 ...
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 ...
Analyse der Konfiguration bei der Approximation ungleichmäßig abgetasteter Oberflächen auf Basis von Nivellements und terrestrischen Laserscans
(2015-07-30)
Seit einigen Jahren unterliegt der Bereich der Ingenieurgeodäsie einem starken Wandel, da sich diese Disziplin generell den stetig weiterentwickelnden, anwendungsbezogenen Problemstellungen widmet. Unter diesen Aspekten ...
Convex Optimization for Inequality Constrained Adjustment Problems
(2015-10-14)
Whenever a certain function shall be minimized (e.g., a sum of squared residuals) or maximized (e.g., profit) optimization methods are applied. If in addition prior knowledge about some of the parameters can be expressed ...
Interpretation of L-band brightness temperatures of differently tilled bare soil plots
(2015-12-03)
The structure of the surface soil layer is strongly influenced by soil tillage practices with important consequences for the soil hydraulic properties and soil moisture dynamics in the top soil layer. In this study, an ...
The Impact of Sensor Characteristics and Data Availability on Remote Sensing Based Change Detection
(2014-12-04)
Land cover and land use change are among the major drivers of global change. In a time of mounting challenges for sustainable living on our planet any research benefits from interdisciplinary collaborations to gain an ...
Assessment of health-related risks associated with domestic water uses in the Mekong Delta of Vietnam
(2015-02-27)
The Mekong Delta in the South of Vietnam is characterized by its intensive agricultural production. Access to safe and clean water supplies for drinking and domestic services is poor, especially for rural communities. ...
Experimental and numerical description of rapid granular flows and some baseline constraints for simulating 3-dimensional granular flow dynamics
(2014-07-25)
Accurate prediction of rapid granular flow behavior is essential to optimize protection measures from hazardous natural granular flows like snow avalanches and landslides and to design efficient production facilities for ...
