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...

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...

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...

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...
