WG-PSS - we need your nominations and proposals
Raphael.Vis...@csiro.au
Dear Colleagues,
During the 3rd Global Workshop on PSS in Potsdam, I mentioned that we need your nominations for:
(i) the new leadership of our WG for the term 2013-2017, and
(ii) proposals for hosting the 4th Global Workshop.
I now ask that you please send Slava and I (raphael.visc...@csiro.au, viachesla...@mcgill.ca) your nominations/proposal by Monday 2 September. We propose to distribute the ballot for both of these soon after.
Some details on these below.
1. Nominations for new leadership:
Currently we have three nominations for Chair and two for Vice Chair.
For the nominations, we have decided that the Chair should be a soil scientist while the Vice Chair need not necessarily have a soil science background and might, for instance, be an agricultural engineer, agronomist, chemometrician. For both positions however, it is essential that the candidates have a demonstrated interest in proximal soil sensing.
When nominating, please include a short sentence why you think they would make excellent Chair/Vice Chair of our WG.
The responsibilities for these positions are not particularly onerous, but we need enthusiastic and motivated leaders to help promote and guide the WG. Some of the responsibilities of the Chair and Vice Chair include coordination with the relevant IUSS commissions (e.g. Pedometrics) and working groups (e.g. DSM, Soil monitoring), help with the organising of special events and publications, coordination of workgroup activities and website support.
2. Proposals to host the next workshop:
Currently we have to proposals.
Proposals to host the next workshop need to be in writing (please no more than two pages) indicating the following details:
- Local organisers and contact details
- Current work being performed by host institutions - should be of interest to the WG-PSS
- Possible venues and field day demonstration - the field day is an important part of our meetings
- Additional courses? For instance, there was one in Potsdam on using R for PSS
- Location and logistics
- Social events
- Potential sponsors
For the current two proposals, please prepare the details as above in writing and send them to us. We will distribute these (with any others) when we send out the ballots so that people have the details needed to vote.
We look forward to hearing from you
Raphael and Slava.

We have a postdoc position available at Montpellier - France, with title : "Impact of the spectral resolution of Hyperspectral Vis-NIR data on soil properties mapping"
Context of the research
This research will contribute to the French HYPXIM hyperspectral space sensor definition. The postdoctoral position is hosted at INRA (UMR LISAH) in close collaboration with IRTSEA (UMR ITAP).
Job description
HYPXIM is a new French hyperspectral space sensor (0.4-2.5μm), planned to be launched in 2019, which will meet the needs of a wide community of users in the world, including in soil science. One of the HYPXIM missions will be the quantification of physico-chemical and bio-chemistry soil
properties and the study of their roles in the hydrological cycle and climate change. The choice of the spectral resolution is still under discussion (between 6 to 15nm). The aim of this post-doctoral research is to examine the possibilities of this new hyperspectral sensor to extract topsoil properties (Texture, Calcium Carbonate, iron...) under varying spectral resolutions.
Different tasks would have to be conducted including the following:
- Simulation of HYPXIM hyperspectral data at several spectral resolutions (6, 10 and 15nm), using Lab Vis-NIR spectra.
- Analysis of soil properties prediction performances at each spectral resolution, using PLSR models and HYPXIM data simulated from Lab spectra.
- Simulation of HYPXIM hyperspectral data with several spectral resolutions (at 6, 10 and 15nm), using HySpex airborne Vis-NIR spectra.
- Development of methods for soil properties estimation, adapted to each spectral resolution. (based on regression models or spectral absorption features study).
- Mapping of soil properties from HYPXIM data simulated from HySpex data and Analysis of uncertainties affecting predictions
The successful candidate will be expected to attend an international conference in 2014 and to publish his results in international peer-reviewed journals.
Avalaible data :
- Vis-NIR HYSPEX airborne data (acquired in 2013 in Mediterranean area in France).
- HYPXIM space data at 4, 8, 20 and 30m of spatial resolution, simulated from Vis-NIR HYSPEX airborne data.
- Around 200 soil samples with Lab Vis-NIR spectra (ASD FieldSpect III) and physico-chimical analysis (texture, CaCO3, iron, pH, CEC, organic matter...).
Qualifications:
The candidate must have skills in remote sensing and/or soil sciences, scientific programmation (Matlab, R or IDL), with notions of statistics and/or chemometrics.
Timing :
Duration : 12 months, Beginning : before end of 2013
Applications:
Candidates should submit, by email, a cover letter with a statement of research interests and a CV to Cécile Gomez (UMR LISAH, Montpellier, France)

With my best Regards,
Cécile Gomez.
A postdoctoral position is proposed by the Institut Agronomique et Vétérinaire (IAV) of Rabat (Morocco), in close collaboration with the Laboratoire d'étude des Interactions - Sol - Agrosystème - Hydrosystème (UMR LISAH, Montpellier, France).
The fellowship is awarded for an initial period of 12 months with a possibility for a second year. The fellowship will be located in IAV Rabat (Morocco) with large visiting periods in LISAH (Montpellier). The salary will be around 1000€ per month, with allowances for the visiting periods in France.
Job description :
The successful candidate will develop new procedures of high resolution mapping of the surface and deep soil properties that are required by the parametrizations of SWAT model and by Integrated Hydrological Processes Model. The methodology will include two steps:
i) extending the successful mapping of some topsoil properties obtained by using airborne hyperspectral images to larger areas by using remote sensing data at coarser spatial and spectral resolutions that are available at lower costs from spaceborne sensors (Ex: Advanced Land Imager (ALI), ASTER and LANDSAT sensors)
ii) merging the outputs of the previous step with legacy soil measured profiles to infer deep soil properties by means of spatial statistic procedures.
Methodologies will be developed in La Peyne and Lebna catchments where soil datasets have been already collected. Validation of the entire approach will essentially take place in the Tleta catchment (Northern Morocco) in which a validation dataset will be collected. Partial validations will also be performed in La Peyne and Lebna catchments where soil datasets have been already collected.
Applications: Candidates should submit, by email, a cover letter with a statement of research interests and a CV to Mohamed Chikhaoui (IAV, Rabat, Morocco, mchik...@gmail.com) and
Cécile Gomez (UMR LISAH, Montpellier, France, gomez....@supagro.inra.fr).
