The GOLM-database standard- a framework for time series data management based on free software

Mareike Eichler, Till Francke, David Kneis & Dominik E. Reusser
Monitoring and modeling projects usually involves time series data originating from different sources. Often, file formats, temporal resolution, and metadata documentation rarely adhere to a common standard. As a result, much effort is spent on converting, harmonizing, merging, checking, resampling, and reformatting these data. Moreover, in work groups or during the course of time, these tasks tend to be carried out redundantly and repeatedly, especially when new data becomes available. The resulting duplication of data...

Soil moisture estimation under vegetation from PALSAR FBD data by means of polarimetric decomposition techniques

Christian N. Koyama, Peter Fiener & Karl Schneider
The disturbing effects caused by vegetation and surface roughness are major impediments to accurate quantitative retrievals of soil moisture from Synthetic Aperture Radar (SAR). With most of the operational spaceborne systems it is not possible to separate the different scattering contributions of the soil and vegetation components. In this study we use the coherent-on-receive dual-pol standard acquisitions (FBD343) of Phased Array type L-band Synthetic Aperture Radar (PALSAR) aboard the Advanced Land Observing Satellite (ALOS 'Daichi')...

In the same period, the demand for local high resolution data in a spatial, temporal, and...

Airborne Remote Sensing for High Throughput Phenotyping of Wheat

Maria Tattaris, Matthew Reynolds, Julian Pietragalla, Gemma Molero, Mariano C. Cossani & Marc Ellis
High resolution remote sensing (RS) of light spectra reflected from plants allows for non-intrusive monitoring of physiological characteristics such as canopy temperature, hydration status, and pigment composition, as well as permitting estimates of agronomic traits such as biomass and yield. While satellite mounted RS platforms have proven efficient at measuring some of these characteristics at a field scale, their spatial resolution is too low for accurate data retrieval at plot level in a plant breeding...

Improving estimation of woody aboveground biomass in drylands by accounting for disturbances and spatial heterogeneity

Liana Kindermann, Magnus Dobler, Daniela Niedeggen & Anja Linstädter
Existing methodologies for estimating woody aboveground biomass and carbon stored therein have been developed for forests but are not tailored to the vast dryland ecosystems where vegetation is heterogenous and highly disturbed. Still, those methods are widely applied with questionable results and possible problematic implications, not only for biomass quantification but also for disturbance ecology, biodiversity research, and ecosystem service assessments. We hereby propose a new methodology especially designed to encompass small, disturbed, and irregular...

Sensor and data fusion technologies in archaeology

Jay K. Johnson & Bryan S. Haley
Remote sensing in prehistoric archaeological research in North America has come to rely on geophysical techniques. This paper reviews their application and efficiency in exploring a group of late prehistoric sites in northern Mississippi. While most archaeologists agree that the use of multiple instruments enhances a geophysical survey, there has been little work done on exploring the potential of using multivariate statistics to integrate the resultant data. Two approaches to this challenge are explored.

Dirk Hoffmeister, Juliane Bendig & Guido Waldhoff
Full-Waveform airborne laser scanning (ALS) is a novel method for observing the earth surface. It is suitable for the extraction of digital elevation models (DEM) and for estimating, for example buildings, single trees, and wooded areas, as 3D information. In this contribution, the processing of data from a flight survey with Riegl’s LMS-Q560 on 30 July 2008 is described. The accuracy of the extracted data was determined by comparison with official geodata and remote sensing...

Remote Sensing of Plant Pigments in Coastal Aquatic Systems

Natascha Oppelt
In coastal aquatic systems, marine macroalgae provide food and habitat for wildlife. Analysis of their occurrence and socialization therefore enables an estimate the state of coastal marine environment and provides evidence for environmental changes. To identify different macroalgae at family or species level, we have to identify their specific pigment composition. Hyperspectral sensors with their narrow band widths enable the detection of local absorption features of pigments and increased the number of possibilities to determine...

Millimeter Wave SAR for UAV-based Remote Sensing

Michael Caris & Stephan Stanko
The airborne monitoring of civilian and military scenes (using unmanned aircraft) is becoming increasingly important. Several types of airborne sensors in the optical, infrared or millimeter wave spectrum - are available for the different platforms. Beside the all-weather suitability of the sensors, the recent deployment scenarios, often in deserts or arid environments, also demand for the ability to look through dust clouds and sandstorms. The only sensor, which is capable to cope with such...

Living at the lakeshore. Early Nubian Complex site associated with a lacustrine environment

Karin Kindermann, Philip Van Peer, Felix Henselowsky & Olaf Bubenzer
By analysing satellite images of the area around Sodmein Cave numerous well-preserved surface remnants (terraces) could be documented. Surveys on these old terraces, showing mainly a dark desert pavement, yielded preferentially Pleistocene artefact concentrations. Hence, it became clear that these terraces represent parts of the former Pleistocene surface of the area. During surveying activities on such terraces a new archaeological site – preliminary named as “Sodmein Playa” 14/01 – was discovered around 3 km south-west...
