A post-doctoral position is available at the Centre for Sustainable Forestry and Climate Change at Forest Research, Farnham, England (https://www.forestresearch.gov.uk) to work jointly with the Computer Graphics & Geometry team at the University of Strasbourg, France (http://icube-igg.unistra.fr/en/). The two teams have been working together with colleagues worldwide on Terrestrial Laser Scanner (TLS)-based methods of data collection and post-processing for several years (https://www.youtube.com/watch?v=jjtVhjx8-3Q); in order to produce more accurate, harmonized and timely information that can be fed into national and international forest information systems.
Terrestrial laser scanning technologies are being used by forest scientists, in a non-destructive way, to provide precise and reproducible information on above-ground wood volume and biomass of trees. This capability will benefit assessments of how much carbon forests absorb and how they might respond to climate change. However, the performance of these technologies still must be challenged when applied to large ranges of both forest stand area and structural complexity, where the level of signal occlusion is one of the key factors which may influence its resolving power.
The objectives of the selected candidate will be to: 1) deliver a TLS simulator for realistic 3-D point cloud computations from virtual forest stands; 2) computer generate 3-D virtual forest stands of contrasting structural complexities from a large collection of tree and shrub Quantitative Structure Models (QSMs, see https://www.isprs-ann-photogramm-remote-sens-spatial-inf-sci.net/II-3-W4/189/2015/isprsannals-II-3-W4-189-2015.pdf) and 3) recommend optimal TLS survey plans (e.g., number, position... etc.) by considering effects of signal occlusion levels on tree volume estimates as quantified from this study.
The position is a one-year contract with the University of Strasbourg and it is open to citizens from all nationalities. Candidates will be subject to UK immigration requirements as well as to Civil Service nationality rules. Gross salary will be around 2900 € per month. We are seeking a highly motivated and independent scientist with a PhD in computer science, applied mathematics or a related field. Previous experience or a strong interest in laser technologies and forestry will be appreciated, as well as good inter-personal skills. Applications must include a CV, a cover letter describing previous research experience and motivations for the position (one A4 max), and names and e-mail addresses of three referees. Applications must be sent by e-mail to Franck Hétroy-Wheeler (firstname.lastname@example.org) and Eric Casella (email@example.com) before the 1 st of July 2019 for an expected start in September 2019. The position will remain opened until filled.
