In this study, an in situ application for identifying neodymium (Nd) enriched surface materials that uses multitemporal hyperspectral images is presented (HySpex sensor). Because of the narrow shape and shallow absorption depth feature, a method was developed enhancing extracting necessary information from image spectra, even under illumination conditions are not optimal. For purpose, two following approaches were developed: (1) reducing noise analyzing changing by averaging scenes (2)...
Abstract Structural Health Monitoring (SHM) of civil engineering structures is experiencing an increasing progress in the last decades. The present work focuses on static behavior a highway bridge due to environmental temperature effects. goal study was test applicability satellite-based synthetic aperture radar interferometry (InSAR) for deformation monitoring large, curved and compare obtained results with alternative measurement techniques like classical geodesy surveying advanced...
Hyperspectral images are of increasing importance in remote sensing applications. Imaging spectrometers provide semi-continuous spectra that can be used for physics based surface cover material identification and quantification. Preceding radiometric calibrations serve as a basis the transformation measured signals into units such radiance. Pushbroom sensors collect incident radiation by at least one detector array utilizing photoelectric effect. Temporal variations characteristics differ...
As geothermal energy is of increasing importance as a renewable source, there high demand for comprehensive studies to prevent failure during implementation, the case in Staufen im Breisgau, Germany. The drilling seven wells heating city hall 2007 thought have disturbed existing hydro-geological system complex structured transition zone Upper Rhine Graben and Schwarzwald massif. This event has led uplift, related transformation anhydrite gypsum, which affects infrastructure centre via...
Abstract. Imaging spectroscopy is increasingly used for surface mapping. Therefore different expert systems are being utilized to identify cover materials. Those mainly rely on the spectral comparison between unknown and library spectra, but their performances were only limited qualified. This study aims comparative analysis of drill core samples from recently discovered maar system in Czech Republic. Drill surrounding area Mýtina analyzed by X-Ray diffraction (XRD) hyperspectral...
The city of Staufen im Breisgau in southwest Germany suffers from a localized land uplift, which has occurred the past six years relation to geothermal drilling activities 2007. So far, severe damages at 269 buildings have been recorded. chemical transformation anhydrite and water gypsum, resulting volume increase, attributed as cause uplift. Previous studies provide knowledge on spatio-temporal displacement evolution 2008 through 2011 using leveling spaceborne Synthetic Aperture Radar...
There has been growing interests in recent years for the safe underground storage of carbon dioxide (CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) as a potential technology preventing this greenhouse gas from entering atmosphere. As suitable locations geological may be diverse, applicability various geodetic and geophysical methods surveillance monitoring purposes must investigated. In paper, we evaluate ground surface...
The city of Staufen im Breisgau has been experiencing a strong uplift phenomenon since the end 2007, resulting in severe damages to more than 260 buildings. process attributed disturbance hydrogeological system region due drilling activities for geothermal heating and cooling management hall. This paper focuses on using InSAR time series methods Persistent Scatterer Interferometry (PSI) Small Baselines Subset (SBAS) derive displacement map from July 2008 till May 2011.

Hyperspectral rare earth elements detection in space borne and near-field acquired images becomes more important for global exploration. In comparison to classic exploration methods, the benefit of hyperspectral surveys is fast in-situ generation spatial information. Current investigations do include element mappings - one new tool mapping REEMAP algorithm. So far it trained five (erbium, dysprosium, holmium, neodymium thulium). Previous versions did not map samarium. The here presented...
