The accumulation of evidences of the effects of intensive agricultural practices against wildlife fauna and flora, and biodiversity in general, has been largely published in scientific papers (Tildman, 1999). However, data serving as support to their conclusions are often kept hidden behind research institutions. This paper presents a data visualization system opened on the Web allowing citizens to get a comprehensive access to data issued from such kind of research institution, collected for more than 20 years. The Web Information System is based on a responsive design allowing access for various mobile devices, and has been thought in order to ease the comparison of data issues from various databases describing the same object, the agricultural landscape, but at different scales and through different observation devices. An interactive visualisation is proposed in order to check co-evolution of fauna and flora together with agricultural practices. It mixes aerial orthoimagery produced since 1950 with vectorial data showing the evolutions of agricultural parcels with those of a few sentinel species such as the Montagu's harrier. This is made through a composition of maps, charts and time lines, and specific tools for comparison which present the most expressive data aggregates. A particular concern is given to the observation effort bias in order to show meaningful statistical aggregates. The architecture of the system supporting this proposal tries to be efficient, based on a data-driven paradigm : it looks like a TJS Web service serving statistical summaries displayed through the use of D3.js and OpenLayers 3 libraries.

PhD Student
University of La Rochelle

Christine Plumejeaud-Perreau received her master degree in applied mathematics in
2000, a research master in 2006 at LIG laboratory at Grenoble, France, followed by a
PhD Thesis defended in 2011. She got a reward from the geomatics community through
the GDR MAGIS price honoring her PHD’s work on spatio-temporal databases for
making long-term and sustainable information systems for socio-economic statistics.
She works at CNRS in an interdisciplinary laboratory, mixing ecology,
biology, geography, history and geosciences disciplines. Her competences address the field
of computer science and geomatics, as well as the edge of data science analysis through
spatio-temporal analysis and statistics.

Kelleann Foster, RLA, ASLA is Associate Dean and Director of the Stuckeman School of Architecture and Landscape Architecture at Penn State University. She is a licensed landscape architect whose research focuses on designing sustainable communities. She has 30+ years of professional practice experience and over 25-years at Penn State. Her recent sabbatical, based at Esri, resulted in Penn State’s new online Geodesign graduate programs. Much of Kelleann’s work uses computer technologies to communicate alternative scenarios. Her work has received national and international recognition. Her expertise, highlighted in a recent publication in a special issue of Landscape and Urban Planning titled “Geodesign parsed: Placing it within the rubric of recognized design theories,” places her among leaders of the emerging field of geodesign.
