gms-index-mediator: a R-tree-based in-memory index for fast spatio-temporal queries for the GeoMultiSens platform

Daniel Eggert, Mike Sips & Doris Dransch
Gms-index-mediator is a standalone index for spatio-temporal data acting as a mediator between an application and a database. Even modern databases need several minutes to execute a spatio-temporal query to huge tables containing several million entries. Our index-mediator speeds the execution of such queries up by several magnitues, resulting in response times around 100ms. This version is tailored towards the GeoMultiSens database, but can be adapted to work with custom table layouts with reasonable effort.

Data to Understanding soil and plant interaction by combining ground‐based quantitative electromagnetic induction and airborne hyperspectral data

Christian Von Hebel, Maria Matveeva, Elizabeth Verweij, Patrick Rademske, Manuela Sarah Kaufmann, Cosimo Brogi, Harry Vereecken, Uwe Rascher & Jan Van Der Kruk
This data set contains ground-based apparent electrical conductivity (ECa) of eight depth ranges of investigation. These were inverted for a three-layer electrical conductivity model. Five .dat files contain the depth-specific inverted electrical conductivity and respective layer thicknesses. Three dat-files correspond to airborne plant performance data. Additionally, six figures show the linear regressions between soil information (electrical conductivity property) and plant performance and one video shows the quasi-3D EMI inversion results.

Building monitoring and decentralized, on-site Earthquake Early Warning system for the Kyrgyz capital Bishkek. Several low cost sensors equipped with MEMS accelerometers have been installed in eleven buildings within the urban area of the city. The different sensing units communicate with each other via wireless links and the seismic data are streamed in real-time to data centres at GFZ and the Central Asian Institute for Applied Geoscience (CAIAG) using internet. Since each sensing unit has...

ACROSS Strong Motion Network in Central Asia

J. Lauterjung, M. Pittore, D. Bindi, T. Boxberger, K. Fleming, M. Haas, B. Moldobekov, S. Orunbaev, S. Parolai, B. Petrovic, M. Pilz, J. Stankiewicz & A. Zubovich
Earthquake Early Warning and Rapid Response Systems (EEWRRS) should be a viable complement to other disaster risk reduction strategies, particularly in economically developing countries. The „Early Warning and Impact Forecasting“ group (GFZ, section 2.6) is actively involved in the development of novel strategies to develop scientific and technological solutions that may be efficiently applied in countries with limited resources. The proposed solution includes a risk estimation module that extracts from a portfolio of precomputed impact...

The international consortium, representing academic, geothermal sites and industry, will utilize the latest developments in the use of hydraulic, chemical and thermal treatments for enhancing the productivity of geothermal reservoirs, with considerable interaction with various interests groups and the thorough...

MI-DAM - MultI-parameter monitoring and real-time risk assessment of hydroelectric DAMs in the Kyrgyz Republic

J. Lauterjung, M. Pilz, Y. Petryna, T. Boxberger, S. Orunbaev & B. Moldobekov
The MI-DAM project will develop a robust, low-cost, and adaptable system that includes an early warning element and time-variable fragility functions. The system will continuously monitor the health of hydroelectric dams and the surrounding slopes, undertake on-site processing of recordings by multi-parameter sensors, and forward the most relevant information to response centers (e.g., civil protection). As an example, the project will focus on the Toktogul dam in Central Kyrgyzstan. Waveform data are available from the...

Fibre-optic distributed acoustic sensing data from Reykjanes, Iceland

Philippe Jousset, Thomas Reinsch, Trond Ryberg, Hanna Blanck, Andy Clarke, Rufat Aghayev, Gylfi Páll Hersir, Jan Henninges, Michael Weber & Charlotte Krawczyk
Imaging the internal structure of faults remains challenging using conventional seismome-ters. Here, the authors use deployed fibre-optic cables to obtain strain data and identify faults and volcanic dykes in Iceland. Such fibre-optic networks are pervasive for telecommu-nication and could be used for hazard assessment. Natural hazard prediction and efficient crustal exploration requires dense seismic observa-tions both in time and space. Seismological techniques provide ground-motion data, whose accuracy depends on sensor characteristics and spatial distribution. In...

Smoothed global stress maps based on the World Stress Maps database release 2016

Oliver Heidbach & Moritz Ziegler
The World Stress Map (WSM) is the global compilation of information on the present-day stress field in the Earth's crust. The current WSM database release 2016 (Heidbach et al., 2016) has 42,870 data records, but the data are unevenly distributed and clustered.To analyse the wave-length of the crustal stress pattern of the orientation of maximum horizontal stress Shmax, we use so-called smoothed stress maps that show the mean SHmax orientation on regular grids. The mean...

Data supplement to "Pedogenic and microbial interrelations to regional climate and local topography: New insights from a climate gradient (arid to humid) along the Coastal Cordillera of Chile"

Bader, Karen Baumann, Friedhelm Von Blanckenburg, Jens Boy, Liesbeth Van Den Brink, Emanuel Brucker, Burkhard Büdel, Rafaella Canessa, Michaela A. Dippold, Todd A. Ehlers, Juan P. Fuentes, Roberto Godoy, Patrick Jung, Ulf Karsten, Moritz Köster, Yakov Kuzyakov, Peter Leinweber, Harald Neidhardt, Francisco Matus, Carsten W. Mueller … & Peter Kühn
The effects of climate and topography on soil physico-chemical and microbial parameters were studied along an extensive latitudinal climate gradient in the Coastal Cordillera of Chile (26° - 38°S). The study sites encompass arid (Pan de Azúcar), semiarid (Santa Gracia), mediterranean (La Campana) and humid (Nahuelbuta) climates and vegetation, ranging from arid desert, dominated by biological soil crusts (biocrusts), semiarid shrubland and mediterranean sclerophyllous forest, where biocrusts are present but do have a seasonal pattern...

Brittle models of fault-volcano interactions during extension

Ada De Matteo, Giacomo Corti, Benjamin Van Wyk De Vries, Bruno Massa & Giulio Mussetti
This dataset contains 11 top view photographs of fault pattern in sand surfaces from a series of analogue tectonic experiments run to investigate the interaction between faults and volcanic features in areas characterized by pure extension, such as in rift areas (de-Matteo_2018-004_datasets.zip: Fig 02 – Fig 12). Additionally, a figure with a sketch of the experimental setup is provided (Fig 01), a file describing experimental settings for analogue experiments (Table 1.pdf) and a file with...

psi-explorer: a visual-analytics approach for the assessment of persistent scatterer interferometry (PSI) data

Daniel Eggert, Patrick Köthur & Doris Dransch
The processing of Persistent Scatterer Interferometry (PSI) data and the estimation of displacement is a nonlinear and user-driven procedure that can introduce large errors for noisy backscatter points. Results may differ significantly depending on chosen thresholds, filter settings, constraints and final interpretation. Thus the identification of valid PS with rather low errors in the SAR data is a crucial step in the PSI workflow. PSI-Explorer is a scientific prototype of our visual-analytics (VA) approach supporting...
