Explore the spread of farming systems in Europe from 10,000-5,000 calBP using geostatistic modeling. Includes mapping biomes, space-time markers, gridding, directional derivatives, & integrating with diffusion equations. Contact JP Bocquet-Appel & S Naji for more info.

GEOSTATISTIC MODELING OF THE SPREAD OF FARMER SYSTEM IN EUROPE JP Bocquet-Appel* and S Naji (CNRS, Paris) *bocquet-appel@ivry.cnrs.fr
The maps • Definition of the geographical area (Europe, from Atlantic to Ural?) • Maps of Europe (raster), commun to all the participants, to facilitate thematic interactions and data exchanges • Maps reconstituted of biomes at different time-periods (10,000-5,000 calBP)
Geostatistic modeling: Kridging • The earliest space-time markers for the onset of the agricultural system at the locality (x,y): Data bases of 14C dates • Auditing the databases • Gridding: technique of research for the optimal informed grid (N-points)
Formation of the isochrones indicating the speed of spread • Mapping the direction of spread on the grid (directional derivatives) • Geostatistic modeling: Kridging • Kridging the sample of 14C dates on a grid
Integration of geostatistic modeling of spread of the farming system (speed and direction) with other modeling (diffusion equations 3D…).
