This interpretation leads to a generalisation of the FRFT to more dimensions by stating the question, which unitary operators in the more dimensional Wigner-Ville plane stem from a unitary operator in the space of functions, which are square integrable. It turns out that the more dimensional FRFT can be imbedded in a Lie group of unitary operators on this space, that are related to the symplectic group by means of a Lie group homomorphism. Modern approaches like precision agriculture and integrated pest and disease management rely on the use of models. GIS is indispensable to combine sources of data and to visualize important spatial information. In all, modern production ecology leads to decisions that are better supported by the most recent agricultural knowledge, and hence to more sustainable use of land.
Spatial statistics is important in aspects of production ecology.
Spatial statistics quantifies uncertainty and supports problem solving in issues of scale and spatial modeling. Examples include interpolation of agricultural models to field or regional scales, quantification of uncertainty in GIS, upscaling, and use of remote sensing images for decision support. In association with the International Statistical Institute and sponsored by the Netherlands Academy of Sciences we organize the international conference of Spatial Statistics for Production Ecology. This building has excellent conference facilities with all modern equipments for presentations. It now also hosts the Wageningen UR Geoinformation Centre that is responsible for teaching programmes of geoinformation, takes part in research projects and is a service centre for geodata .
